Description of corresponding document: US4734119
The present invention relates to novel acylated hydrazinomethylphosphonates,
hydrazinomethylphosphinates and hydrazinomethylphosphine oxides which, as herbicide antagonists,
are able to protect cultivated plants from the phytotoxic action of herbicides, in particular of
chloroacetanilide herbicides, to compositions containing an acylated hydrazinomethylphosphonate,
hydrazinomethylphosphinate or hydrazinomethylphosphine oxide, and to compositions which, in
addition to containing such an antagonist (also called antidote or safener), already contain the
herbicide, and to a method of selectively controlling weeds, which comprises the use of a herbicide and
said safener. The invention also relates to the preparation of novel acylated
hydrazinomethylphosphonates, hydrazinomethylphosphinates and hydrazinomethylphosphine oxides.

It is known that herbicides belonging to a very wide range of compound classes such as triazines, urea
derivatives, carbamates, thiocarbamates, haloacetanilides, halophenoxyacetic acids etc., when
employed in an effective concentration, often also damage cultivated plants to a certain extent in
addition to the weeds which it is desired to control. Too high concentrations are often applied
unintentionally and randomly whenever peripheral zones overlap on zonal spraying, whether as a
consequence of the action of wind or through miscalculating the sweep of the spray device employed.
The climatic conditions or the nature of the soil may be such that the concentration of herbicide
reommended for normal conditions acts as an overdose. The quality of the seeds may also be a factor in
the tolerance of the herbicide. To counteract this problem, different compounds have already been
proposed which are able specifically to antagonise the harmful action of the herbicide on the cultivated
plant, i.e. to protect the cultivated plant without noticeably influencing the herbicidal action on the
weeds to be controlled.
However, it has been found that the proposed antidotes very often have a species-specific activity both
with respect to the cultivated plants and to the herbicide and also, in some cases, contingent on the
mode of application, i.e. a specific antidote is often suitable only for a specific cultivated plant and a
few classes of herbicides.
The direct pre- to postemergence treatment of certain useful plants with antidotes as antagonists of
specific classes of herbicides in a crop area is disclosed in German Offenlegungsschrift specifications
Nos. 2 141 586 and 2 218 097 and in U.S. Pat. No. 3,867,444.
Further, German Offenlegungsschrift No. 2 402 983 discloses that maize plants can be effectively
protected against damage by chloroacetanilides by adding an N-disubstituted dichloroacetamide as
antidote to the soil.
The compounds of the present invention are able to protect cultivated plants such as cereals, maize,
rice, sorghum or soybeans from the phytotoxic action of herbicides belonging to different chemical
classes.

Halogen is fluorine, chlorine, bromine and iodine, with chlorine being preferred.
Effective safeners are such compounds of formula I, wherein
R1 and R2 are each C1 -C4 alkoxy (phosphonates),
R1 is C1 -C4 alkoxy and R2 is C1 -C4 alkyl (phosphinates),

hydrazino-N-methoxycarbonyl-N'-chloroacetyl-N'-methyl-O,O-diethylphosphonat e,
hydrazino-N-methoxycarbonyl-N'-dichloroacetyl-N'-methyl-O,O-diethylphosphon ate,
hydrazino-N-t-butyloxycarbonyl-N'-chloroacetyl-N'-methyl-O,O-diethylphospho nate,

hydrazino-N-benzyloxycarbonyl-N'-dichloroacetyl-N'-methyl-O-ethylmethylphos phinate and
hydrazino-N-benzyloxycarbonyl-N'-dichloroacetyl-N'-methyl-O-ethylethylphosp hinate.
The preparation of the novel acylated hydrazinomethylphosphonates, hydrazinomethylphosphinates
and hydrazinomethylphosphine oxides of formula I is effected in a manner known per se.
The synthesis steps may be illustrated for example by the following equations: ##STR3##
The derivative of the respective phosphorous, phosphonic or phosphinic acid is condensed with an
alkylidenehydrazine which is protected by a carbonic acid radical thus affording an acylated
hydrazinomethylphosphonate, hydrazinomethylphosphinate or hydrazinomethylphosphine oxide.
If R1 and R2 are alkyl radicals, an acylated hydrazinomethylphosphine oxide is also obtained as
follows: ##STR4##
The halomethylphosphine oxide is condensed with a carbazate.
These condensation reactions are carried out in an inert organic solvent.
The protective group --COOR7 can, if desired, be removed ##STR5##
This removal is effected by simple hydrolysis in alkaline or acidic medium or also by hydrogenolysis
in acidic medium with hydrogen and a catalyst such as palladium on activated carbon if R7 is benzyl.
The above mentioned hydrazinomethylphosphonyl, hydrazinomethylphosphinyl and
hydrazinomethyloxophosphino derivatives can be acylated with 1 or 2 molar equivalents of
haloalkanoyl halide or haloalkenoyl halide. ##STR6##
These reactions are carried out at low temperature in the range from -20 DEG C. to +50 DEG C. in an
inert organic solvent in the presence of at least an equimolar amount of an acid acceptor.
If R4 or R5 is an alkyl, alkenyl, alkynyl or aralkyl radical, said radicals may be introduced into a
compound of formula I by alkylating an acylated hydrazinomethylphosphonate,
hydrazinomethylphosphinate or hydrazinomethylphosphine oxide of the formula below with X--R8
##STR7##
These reactions are also carried out in an inert organic solvent in the presence of at least an equimolar
amount of an acid acceptor.
4/612
In the above equations R1, R2, R3, R5, R6, R9 and R10 are as defined for formula I, Hal is halogen,
preferably chlorine or bromine. The process of the present invention for the preparation of a compound
of formula I comprises reacting a hydrazinomethylphosphonate, hydrazinomethylphosphinate or
hydrazinomethylphosphine oxide of formula II ##STR8## wherein R1, R2, R4, R5, R9 and R10 are as
defined for formula I, in an inert organic solvent in the presence of at least an equimolar equivalent of
an acid acceptor with an acyl halide of formula III
R3 --Hal
(III),
wherein R3 is as defined for formula I and Hal is chlorine or bromine.
Suitable inert organic solvents for these reactions are in particular halogenated hydrocarbons such as
chloroform, methylene chloride, ethylene chloride and also aromatic compounds such as benzene,
toluene or xylene. Further suitable inert organic solvents are ethers such as diethyl ether, dioxane or
tetrahydrofuran, higher boiling hydrocarbons such as cyclohexane or dimethylformamide, as well as
mixtures of such solvents.
The reaction is carried out in the temperature range from -20 DEG to the boiling point of the solvent.
When the condensation reactions exotherm, it is convenient to cool the reaction mixture initially, so
long as hydrogen halide evolves, and, at the conclusion of the reactions, after all has been added, to stir
the mixture further with heating.
Depending on the end use, the safener or antidote of the formula I can be used for pretreating seeds of
the cultivated plant (dressing of the seeds or cuttings) or it can be added to the soil before or after
sowing. However, it can also be applied pre- or postemergence by itself alone or together with the
herbicide. The treatment of the plant or seeds with the safener can therefore in principle be carried out
irrespective of the time of application of the phytotoxic chemical. It can, however, also be carried out
by simultaneous application of phytotoxic chemical and safener (tank mixture). The pre-emergence
treatment includes both treatment of the crop area before sowing (ppi=pre-plant incorporation) and
treatment of the crop areas after sowing but before emergence of the plants.
The rates of application of the safener with respect to the herbicide depend largely on the mode of
application. Where a field treatment is carried out, either simultaneously as tank mixture or with
separate application of herbicide and safener, the ratio of safener to herbicide is in the range from 1:100
to 5:1. Full protective action is usually obtained at a ratio of safener to herbicide of 1:5 to 1:50. When
dressing seeds and taking similar specific protective measures, however, much lower amounts of
safener are required compared with e.g. the amounts of herbicide later employed per hectare of crop
area. For seed dressing, 0.1 to 10 g of safener per kg of seeds are normally required. Full protection is
usually obtained with 0.1 to 2 g of safener per kg of seeds. If it is desired to apply the safener shortly
before sowing by seed soaking, antidote solutions which contain the active ingredient in a
concentration of 1 to 10,000 ppm are used. Full protective action will normally be obtained with
safener concentrations of 100 to 1000 ppm.
As a rule there is a substantial interval of time between protective measures such as seed dressing and
treatment of seedlings with a safener of the formula I and the possible later field treatment with
agricultural chemicals. Pretreated seeds and plants can later come in contact with different chemicals in
agriculture, horticulture and forestry. Accordingly, the invention relates to plant protection
compositions which contain a safener of the formula I as active ingredient, together with conventional
carriers. If appropriate, such compositions may be additionally mixed with the chemical from whose
effects it is desired to protect the cultivated plant.
Cultivated plants within the scope of this invention are all plants which, in any form, can be harvested
(seeds, roots, stalks, tubers, leaves, blossoms) and from which extracts can be obtained (oils, sugar,
starch, protein) and which are cultivated for this purpose. These plants comprise e.g. all species of
cereals such as wheat, rye, barley, oats and, in particular, rice, sorghum, maize, and also cotton, sugar
beet, sugar cane, soybeans, beans, and peas.
The safener can be employed wherever it is desired to protect a cultivated plant of the kind indicated
above from the harmful effects of an agricultural chemical. As already mentioned, possible agricultural
5/612
chemicals are primarily herbicides of the most widely varying compound classes, in particular
haloacetanilides and thiocarbamates.
Numerous haloacetanilides whose harmful effects on cultivated plants can be antagonised with the
novel hydrazinomethylphosphonates, hydrazinomethylphosphinates and hydrazinomethylphosphine
oxides of the formula I are known in the art (q.v. German patent applications Nos. 2 305 495, 2 328

preferably chlorine or bromine, each of R4 and R5 independently of the other is hydrogen, halogen,
lower alkyl, alkoxy, alkylthio, haloalkyl, alkoxyalkyl or alkylthioalkyl, Z is hydrogen, halogen, lower
alkyl, alkoxy, alkylthio, haloalkyl, alkoxyalkyl or alkylthioalkyl, which radicals Z are preferably in the
3-position with respect to the nitrogen atom, n is 0 to 3, A is alkylene, preferably methylene, 1,1ethylene, and 1,2-ethylene which may be substituted by 1 or 2 lower alkyl groups, and R6 is lower

Other suitable herbicides are .alpha.-(phenoxyphenoxy)propionic acid derivatives and .alpha.-(pyridyl2-oxyphenoxy)propionic acid derivatives.
The concentration of safener, provided it is not used for seed dressing, varies from about 0.01 to 5 parts
by weight per part by weight of herbicide. The most suitable ratio for achieving optimum effects in the
particular cultivated plant is determined from case to case, i.e. depending on the type of herbicide
employed.
The compounds of formula I are used in unmodified form or, preferably, as compositions, together
with the adjuvants conventionally employed in formulation technology, and are therefore formulated in
known manner to emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions,
wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymeric
substances. As with the nature of the compositions, the methods of application such as spraying,
atomising, dusting, scattering or pouring are chosen in accordance with the intended objectives and the
prevailing circumstances.
The formulations, i.e. the compositions containing the compound of the formula I and, where
appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g. by homogeneously mixing
and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where
appropriate, surface-active compounds (surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms,
e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl
phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their
ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether,
ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone,
dimethylsulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils such as
epoxidised coconut oil or soybean oil; or water.
The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such
as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it
8/612
is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable
granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or
bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. In additon, a great
number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite
or pulverised plant residues.
Depending on the nature of the compound of the formula I to be formulated, suitable surface-active
compounds are nonionic, cationic and/or anionic surfactants having good emulsifying, dispersing and
wetting properties. The term "surfactants" will also be understood as comprising mixtures of
surfactants.
Suitable anionic surfactants can be both water-soluble soaps and water-soluble synthetic surface-active
compounds.
Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted
ammonium salts of higher fatty acids (C10 -C22), e.g. the sodium or potassium salts of oleic or stearic
acid, or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tallow oil.
Mention may also be made of fatty acid methyltaurin salts.
More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty
sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or
unsubstituted dor substituted ammonium salts and contain a C8 -C22 alkyl radical which also includes
the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of ligonsulfonic acid, of
dodecylsulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids. These
compounds also comprise the salts of sulfuric acid esters and sulfonic acids of fatty alcohol/ethylene
oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and
one fatty acid radical containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium,
calcium or triethylanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid
or of a naphthalenesulfonic acid/formaldehyde condensation product. Also suitable are corresponding
phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of
ethylene oxide, or phospholipids.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols,
or saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether
groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the
alkyl moiety of the alkylphenols.
Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with
polypropylene glycol, ethylenediamine propylene glycol and alkylpolypropylene glycol containing 1 to
10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and
10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units
per propylene glycol unit.
Representative examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil
polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol,
polyethylene glycol and octylphenoxyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan and
polyoxyethylene sorbitan trioleate are also suitable non-ionic surfactants.
Cationic surfactants are preferably quaternary ammonium salts which contain, an N-substituent, at least
one C8 -C22 alkyl radical and, as further substituents, lower unsubstituted or halogenated alkyl, benzyl
or lower hydroxyalkyl radicals. The salts are preferably in the form of halides, methylsulfates or
ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium
bromide.
The surfactants customarily employed in the art of formulation are described e.g. in the following
publications:

Ash, "Encyclopedia of Surfactants", Vol. I-III, Chemical Publishing Co., New York, 1980-81.
The herbicidal compositions usually contain 0.1 to 95%, preferably 0.1 to 80%, of a compound of the
formula I, 1 to 99.9%, of a solid or liquid adjuvant, and 0 to 25%, preferably 0.1 to 25%, of a

Whereas commercial products will be preferably formulated as concentrates, the end user will normally
employ dilute formulations. The formulations can be diluted to a concentration as low as 0.001% The
rates of application are normally from 0.01 to 10 kg a.i./ha, preferably from 0.025 to 5 kg a.i./ha.
The compositions may also contain further ingredients such as stabilisers, antifoams, viscosity
regulators, binders, tackifiers, as well as fertilisers and other compounds for obtaining special effects.
The invention is illustrated by the following Examples in which the temperatures are indicated in
degrees Celsius ( DEGC.) and the pressures in millibars (mbar).

Preparation of hydrazino-N-benzyloxycarbonyl-N'-methyldiethylphosphonate (intermediate)
##STR10##
15 g of N-methylenebenzyl carbazate are mixed with 12.2 ml of diethyl phosphite at room temperature
and heated with stirring to 110 DEG. 1 ml of boron trifluoride etherate is added and stirring is
continued for 11/2 hours at 110 DEG-115 DEG, the mixture is cooled and then taken up in methylene
chloride at room temperature. The solvent is removed by evaporation and the residue dried under high
vacuum affording 23.4 g of an orange-brown oil which crystallises on standing.
10/612
Melting point: 56 DEG-57 DEG.
Analysis calculated: C, 49.37%; H, 6.69%; N, 8.86%; P, 9.79%; found: C, 48.6%, H, 6.6%; N, 9.0%; P,
9.8%.
Instead of boron trifluoride ethereate, gaseous hydrochloride acid, tin chloride or an alkali metal
alcoholate can be used as catalyst. The reaction can also be carried out without a catalyst but in that
case at a higher temperature. Instead of methylene chloride, an aromatic solvent such as benzene,
toluene or xylene can be used.
The N-methylenebenzyl carbazate used as starting material was prepared as follows:
A mixture of 102.3 g of benzyl carbazate and 20.3 g of paraformaldehyde in 800 ml of methanol is
heated to 50 DEG. 11.06 ml of triethylamine are added and the mixture is stirred for 2 hours reflux.
The solvent is removed by rotary evaporation. The viscous residue is dissolved in methanol, treated
with activated carbon and filtered and the filtrate is concentrated. The residue is dried under a vacuum
of 1 mbar and at 50 DEG affording 105 g of the title compound as a white powder with a melting point
of 87 DEG-91 DEG. According to the NMR spectrum the product is obtained as monomer. It contains
0.03% water of crystallisation.
Analysis calculated: C, 60.51%; H, 5.68%; N, 15.68%; found: C, 60.5%; H, 5.8%; N, 15.6%.
20 g of benzyl carbazate hydrochloride are dissolved in 200 ml of water. 15 ml of a 37% formaline
solution are stirred in dropwise at circa 15 DEG. After 2 hours the precipitate is filtered with suction,
stirred in two 300 ml portions of water and each time filtered with suction. The precipitate is then
dissolved in methylene chloride, the solution is dried over sodium sulfate and filtered. The solvent is
distilled off and the residue is dried in vacuo affording 15.9 g of N-methylenebenzyl carbazate which
melts at 125 DEG-127 DEG. According to the NMR spectrum the product is obtained as trimer.
Analysis calculated: C, 60.67%; H, 5.66%; N, 15.72%; found: C, 60.2%; H 5.5%; N, 15.8%. Nmethylenecarbazoyl methylester (CH2 .dbd.N--NHCOOCH3), N-methylenecarbazoyl ethylester (CH2
.dbd.N--NHCOOC2 H5) and N-methylenecarbazoyl t-butylester (CH2 .dbd.N--NHCOO t-C4 H9) can
be obtained in similar manner.
The following N-phosphomethylhydrazino compounds can be obtained in the manner described in

BIOLOGICAL EXAMPLES
The ability of the compounds of formula I to protect cultivated plants from the phytotoxic effects of
potent herbicides can be inferred from the following Examples. The compounds of formula I are
referred to as safeners in the test procedures.
EXAMPLE 9
Test with herbicide and safener in maize. Preemergence application of herbicide and safener as tank
mixture
Plastic containers measuring 25 cm.times.17 cm.times.12 cm are filled with sandy loam and LG 5
maize seeds are sown therein. After the seeds have been covered, a dilute solution of the safener to be
tested and the herbicide is sprayed as tank mixture onto the surface of the soil. The protective action of
the safener is evaluated (in %) 21 days after application. Plants treated with herbicide alone (no
protective action) and completely untreated control plants (100% protective action) are used for
reference purposes. The results are reported below.
Herbicide: 2-Chloro-2',6'-dimethyl-N-(ethoxymethyl)acetanilide.

B e s c h r e i b u n g "Verfahren zur Bekämpfung von Pilzkranzheiten bei Pflanzen" Die Erfindung
bezieht sich auf ein Verfahren zur Bekämpfung von Pilzkrankheiten bei Pflanzen und auf
Zusammensetzungen, die sich fUrdieses Verfahren eignen Gemäss der Erfindung wird ein Verfahren
zur Bekämpfung von Pilz- krankheiten bei PfLanzen vorgeschlagen, welches dadurch ausge-führt
wird, dass man auf die Pflanzen, die mit Pilzkrankheiten befallen sind oder bei denen die Gefahr eines
Befalls durch Pilzkrankheiten besteht, ein disubstituiertes Pyrimidinderivatder Formel
EMI2.1
worin -A, -B und -C, Mir -R, -OR, -SR, Halogen, Nitro oder Amino Gruppen stehen; -Y für eine -R, Or, -SR oder eine Halogen-Gruppe steht, vorausgesetzt dass Y Wasserstoff, substituiertes Alkyl, Aryl
oder BB ist, wenn B Wasserstoff ist; und R für Wasserstoff oder eine Kohlenwasserstoff- oder
substituierte Kohlenwasserstoffgruppeateht; oder ein Salz oder einen Ester eines
solchenpyrimtdinderivats aufbringt.
Mit dem Ausdruck "disubstituiertesPyrimidinderivat1, ist eine Verbindung gemeint, in der mindestens
zwei der vierWasserstoff- atome im Pyrimidinring durch andere Gruppen ersetzt worden sind; d.h.
dass mindestens zwei der vier Gruppen A, B, C und YfUr andere Radikale als Wasserstoff stehen. In
den Ausdruck "Amino" sei auch substituiertes Amino eingeschlossen; es wird auch darauf
hingewiesen, dass dieOruppen B und C unter Bildung eines Rings verknüpft sein können. Wenn R
32/612
eine Kohlenwasserstoffgruppe ist, dann enthält sie in zweckmässiger Weise 1 bis 12 Kohlenstoffatome.
Insbesondere Icann sieetne Alkylgruppe mit 1 bis 5 Kohlenstoffatomen sein.
Durch daserfindung,sgemässe Verfahren knnen unter anderem folgende Pilzerkrankungen bei Pflanzen
behandelt werden
Puccinia recondita (Rost) an Weizen
Phytophthora infestens (späte Trockenfäule) an Tomaten
Sphaerotheca fuliginea (pulvriger Mehltau) am Kürbis
Erysiphe graminis (pulvriger Mehltau) an Weizen und Gerate
Podosphaere leucotricha (pulvriger Mehltau) am Apfel
Uncinula necator (pulvriger Mehltau) am Rebstock
Plasmopara viticola (flaumriger Mehltau) am Rebstock
Piricularia oryzae (Brand) am Reis
Venturia inaequalis (Schorf) am Apfel Im allgemeinen ist diefungizide Aktivität dererfindungsgemäss
verwendeten Verbindungen vorbeugend; d.h., wenn die Verbindungen auf gesunde Pflanzen vor einer
Infektion aufgebracht werden, dann verhindern sie eine nachfolgende Infektion solcher Pflanzen.
In einigen Fällen wird diese vorbeugende Aktivität verlagert, wobei beispielsweise der chemische Stoff
inStaubform oder in flüssiger Form auf dieWurzeln der Pflanze aufgebracht wird und von diesen
aufgenommen wird, so dass das Laubwerk eine vorbeugende Aktivität zeigt. Manchmal teigen die
Verbindungen auch eine heilende Aktivität, wobei sie die Krankheit von infizierten Pflanzen
beseitigen.
Bevorzugte Klassen von Pyrimidinderivaten,die gemäss der Erfindung verwendet werden kannen, sind
die folgenden s Derivate, die in 5-Stellung substituiert sind;und Derivate, tn denen -Y für-5t steht.
Verbindungen, die besondersbeim erftndungsgemässen Verfahrenbrauchbar sind, sind die folgenden:
2,5,6-Trihydroxypyrimidin (besonders aktiv gegen Erysiphe graminis bei Weizen); 2,4,6-Trihydroxy5-nitropyrimidin, 2-Mercapto-4,6-dimethylpyrimi din, 2-Chloro-4-amino-5-nitropyrimidin, 6-Bromo4-hydroxy-chinazolen (alle besonders aktiv gegen Plasmoparavitioola); die Hydrochloride von 2Hydroxy-4,6-dimethylpyrimidin, (2-Methylthio-4-methyl-5-n-propyl-6-pyrimidinyl)-benzoat, Diäthyl(4-methyl5-n-propyl-2-n-propylthio-6-pyrimidinyl)-phosphat, (alle besonders aktiv gegen Venturia
inaequalis); 2-Carbamoylmethyal-4,6-dihydroxypyrimidin (besonders aktiv gegen Uncinula
necator);Diäthyl-(2n-propylthio-4-methyl-5-n-propyl-6-pyrimidinyl)-phosphat und die entsprechende
(2-Benzylthio-) verbindung (beide aktiv gegen Piricularia oryzae); 2-Mercapto-4-benzyl-6hydroxypyrimidin, 2-Methylthio-6-dimethylcarbymoyloxypyrimidin, 2-Methylthio-4,5dimethyl-6dimethylcarbamoyloxypyrimidin, diäthyl-(2-methylthio4-methyl-5-n-propyl-6-pyrimidinyl9-phosphat,
2-Äthylthio-4-methyl6-hydroxypyrimidin und 2,4-Dimethyl-5-n-butyl-6-hydroxypyrimidin (alle
besonders aktiv gegen Podsphaera leucotricha).
Die Erfindung betrifft auch fungizide Zusammensetzungen, die als aktiven Bestandteil
Pyrimidinderivate der oben angegeben Formel oder deren Salze enthalten. Diese Zusammensetzungen
kannen zusätzlich feste Verdünnungsmittel, wiez.B. Kaolin, Bentonit oder Talcum; flüssige
Verdünnungsmittel wie z.B. Wasser oder Erdöle, die vorzugsweise ein Netzmittel oder
Dispergiermittel enthalten, insbesondere der kationischen,anionischen oder nichtionischen Type, wie
quaternäre Ammoniumverbindungen, Alkylphenol/ Xthylenoxyd-Kondensate unddgl.; und andere
biologisch aktive Verbindungen enthalten.Wennsie flüssig sind, dann können die
ZusammensetzungenLdeungen, Suspensionen,Emulsionen oder Disperatomen sein, und sie können
auf die Pflanzen durch Bespritzen des Laubwerks, oder, wennzweckmässig, durch Trinken der
Wurzeln derPflanse aufgebracht werden.Leiste Zusammensetzungen kennen, wenn zweckmässig, auf
dem Boden in der Nähe der Basis der Pflanze zur Aufnahme durch die Wurzelnaufgebracht werden,
oder sie können auf das Laubwerk der Pflanze aufgestäubt werden.
Die Zusammensetzungen, die in Porm von wässrigen Lösungen, Suspensionen, Dispersionen oder
Emulsionen verwendet werden sollen, werden im allgemeinen in form eines Feststoffs oder eines
flüssigenKonzentrats, das einen hohen Anteil des aktiven oder der aktiven Bestandteile enthält,
geliefert, wobei das genannteKonzen- trat vor demGebrauch in Wasser dispergiert wird. Diese
Konzentrate müssen oft längere Zeiten einer lagerung standhalten und nach einer solchen Lagerung mit
Wasser verdUnnt werden können, um wässrige Präparate herzustellen, die eine ausreichende Zeit
33/612
homogen bleiben, so dass sie durch eine herkömmliche Spritzeinrichtung angewendet werden
können.Im allgemeinen enthalten Konzentrate inzweckmässiger Weise 10 bis 85 Gew.-% des aktiven
Bestandteils oder der aktiven Bestandteile und im allgemeinen 25 bis 60Gew.-% des aktiven
Bestandteils oder deraktiv standteile. Wenn sie zur Herstellung wässriger Präparate vei werden, dann
könnensolche Präparate dieverschiedensten Mengen des aktiven Bestandteils oderder aktiven
Bestandteile enthal u was von demZweck abhängt, für den sie verwendet werden sollen, aber
einwässriges Präparat, das zwischenO,OOl und 1,0Gew.- des aktiven Bestandteils oder der aktiven
Bestandteile enthalt,wird gewöhnlich verwendet.
Die erfindungsgemäss au verwendenden Pyrimidine können durch Ln der Technik ansich bekannte
Standardverfahren hergestellt werden.Verbindungen, die Substituenten -SR in der 2-Stellung
enthalten, können durchKondensation von Thioharnstoff oder dessen Derivate mit geeigneten ssKetoestern oder ähnlichen Verbindungen hergestellt werden.Beispielsweise kann 2-Mercapto- 4,6dimethylpyrimidin durch Kondensation von Acetylaceton mitThioharnstoff hergestellt werden. In
ähnlicher Weise können 2-Hydroxyverbindungen durch ähnlicheXondensat ionen hergestellt werden,
wobei Harnstoff anstelle von Thioharnstoff verwendet wird.
Halogenverbindungenkönnen durch Halogenierung der entsprechenden Hydroxyverbindungen
hergestellt werden. Aminoverbindungen können durch Umsetzung derentsprechenden
Halogenverbindungen mit einemtiberschuss des entsprechenden Amins hergestellt werden.Nitroverbindungen kennen durchverschiedene Methoden hergestellt werden, beispielsweise kann 2,4,6Trihydroxy-5-nitropyarimidin durch Behandlung von Barbitsäure mit rauchender Salpetersäure
hergestellt werden.
Salze von Verbindungen kennen dadurchhergettellt werden, dass man die Verbindungen mit
konzentrierten starken Säuren, wiez..B.
HCl, behandelt; Salze von Hydroxy- oder Mercaptoverbindungen können auch durch Behandlung mit
starken Alkalien , wie z.B.
NaOH, hergestellt werden. Ester von Verbindungen, wie z.B.Benzoate, Phosphate und Carbamate,
können durch Standardverfahren aus den entsprechenden -OH oder -SH-Ve:tindungen
hergestelltwerden Die Erfindung wird durch diefolgenden Beispiele näher erläutert, Beispiele 1 - 41
Erfindungsgemässe Zusammensetzungen wurden in der forlgenden Weise hergestellt und gegen
verschiedene Pilzkrankheiten bei Pflanzen getestet. DieZusammensetzungen wurden auf vorbeugende,
heilende und verlagerte Aktivität geprüft, und die Resultate sind in der folgenden Tabelleangegeben.
Bei den Vorbeugungstests wurden Pflanzen mit einer Lösung oder Suspension der aktiven Verbindung
in Wasser mit der angegebenen Konzentration (gewöhnlich 500ppa) derart bespritzt, dass die Blätter
nass waren. Das Wasser enthielt 0,1 Gew.-% eines Netzmittels, wie z.B. Äthylenoxyd/OctylphenolKondensat. 24 Stunden nach dem Bespritzen wurden die Pflanzen mit der Testkrankheit geimpft, und
am Ende des Tests wurde das Ausmass der Krankheitvisuell bestimmt.Die Verlagerungstest wurden
in ähnlicher Weite ausgeführt, mit dem Unterschied, das der Boden, in dem die Pflanzen wuchsen,
entweder durch Durchnässen mit der Lösung des aktiven Bestandteils oder durchEinarbeitung einer
festen Zusammensetzung, die denaktiven Bestandteil enthielt, behandelt wurde. 1Bei heilenden
Testswurden die Pflanzen mit der Krankheit geimpft und dann nacheiner Reihe von Tagen, was von
der Krankheit abhing, mit eine Lösung oder Suspension solcher Art, wie sie beim vorbeugenden Test
verwendet wurde, bespritzt (so dass die Blätter nass waren). Die Resultate sind in der Tabelle in
Einstufungen angegeben,welche dasprozentuale Ausmass der Krankheit wie folgtangeben:

schädigend wirkten, wie z.B.
quecksilberorganische oderarsenorganische Verbindungen, bei der Bekämpfung von
ernstenKrankheiten des Reises wie piricularia oryzae und hypochnus sasakii, wegen ihres
ausgezeichneten fungiziden Effekts und aus ökonomischen Gründen verwendet.
Vor kurzem wurde jedoch die Anwendung von organischen Quecksilberverbindungen
alsAckerbauchemikalien während der Wachstumsperiode der Reispflanzen ausGesundheitsgrnden
verboten, da diese eine direkte,bzw0 indirekte Toxizität gegenüber dem menschlichen Körper
41/612
aufweisen0 Dementsprechend war die Entwicklung von billigen und gegen die oben erwähnten
Reiskrankheiten wirkungsvollen Chemikalien, die trotzdem auf Mensch und Haustier weniger toxisch
wirken, ingrossem Stil erforderlich.
Aus der deutschenpatentschrift Nr.1 039 528 ist es bekannt, dass organische Phosphorsäureester der
folgenden allgemeinene Formel insektizide Wirkungaufweisen:
EMI2.3
Darin bedeuten R3 einen niedrigen Alkylrest und R4 ein Wasserstoffoder Chloratom oder einen
Methylrest.
In dieser Patentschrift wird jedoch nichts davon erwähnt, dass man von diesen Verbindungen
fungizide und herbizide Eigenschaften erwarten kann.
Es wurde nun überraschend gefunden, dass die Verbindungen der allgemeinen Formel I
ausgezeichnete fungizide und herbizide Eigenschaften haben.
Verbindungen gemäss der vorliegenden Erfindung sind bei der Bekämpfung von Pflanzenkrankheiten,
die durch verschiedene Pilzarten, wie Archimyceten, Phycomyceten, Ascomyceten, Basidiomyceten
und Fungi imperfectihervorgerufenuerden, wirksam. Spezielle Verbindungen, die Substituenten wie
Methyl-, Äthyl-, n-Propyl-, i Propyl-, n-Butyl-, i-Butyl-, sec.Butyl- oderGyclohexylreste ie- wels für
R1 und R2, Sauerstoff und Schwefel für X, Wasserstoff oder den Methylrest für Z, den Benzylrest,
Phenylrest, chlor-, dichloroder methylsubstituierten Benzyl- oder Phenylrest für Y in der allgemeinen
Formel I aufweisen, haben hervorragende fungizide Wirkung, speziell bei der Bekämpfung von
schweren Krankheiten der Reispflanze, wiez.B. von piricularia oryzae, cochliobalusmvabeanus und
hypochnus sasakii.
Die Verbindungen gemäss der vorliegenden Erfindung zeigen ihre ausgezeichnete Wirkung auch in
Form herbizider Kompositionen.
Sie zeigen eineselll gute selektive herbizide Wirkung, wenn gewisse Mengen vor dem Keimen des
Unkrautes auf den Boden aufgebracht werden. Diese Verbindungen werden sehr wirkungsvoll bei der
Bekämpfung von Unkraut jeglicher Art in den Reisfeldern, wie von Unkräutern der Familie Graminae
von breitblätterigen und vonmehrjähri gen Unkräuternverwendet, ohne dass sie irgendeine
Phytotoxizität für die Kulturpflanzen, speziell für Reispflanzen, besitzen.
Diese Verbindungen töten alles Unkraut, zeigen dann aber keinen selektiven herbiziden Effekt, wenn
sie in grossen Mengen angewendet werden. Der AusdruckUnkraut" bezieht sich im weitesten Sinne
auf alle Pflanzen, die an Stellen wachsen, wo sie unerwünscht sind..
Die Verbindungengemäss der vorliegenden Erfindung besitzen ein weites Spektrum von guten
biologischen Wirkungen. Sie können zur Bekämpfung von Pflanzenkrankheiten speziell Krankheiten
von Reispflanzen, wie oben erwähnt? eingesetzt werden, wenn sie als Fungizide dienen sollen, aber sie
können ebenso zur Bekämpfung von Unkräutern in Reisfeldern gemäss einer anderen
Anwendungsmethode verwendet werden Diese Verbindungen haben vom Standpunkt der
Wirtschaftlichkeit der im agrarischen Produktionsbereich nötigen Arbeit grossen praktischen Wert, wie
auch infolge ihrer produktionssteigernden Wirkung.Ausserdem haben diese Verbindungen einen
grossen Vorteil alsAckerbauchemikalien, da sie keine Schwierigkeiten bezüglich der Resttoxizität von
Anbauprodukten bereiten, zumal sie keine schädlichen Schwermetalle wie die oben genanntenQuecksilberverbindungen enthalten.

eines Zerkleinerungsgerätes in Körner von 0,75 bis 0,38 mm Durchmesser feingeschnitten. Diese
Körner werden dann bei 40 bis 500C getrocknet und es wird ein Granulat erhalten.
Arbeitsbeispiel 4: 2 Teile der Verbindung 9 gemäss der vorliegenden Erfindung und 98 Teile einer
Mischung von Talk und Ton, werden gemischt, gemahlen und in Form einer
Verstäubungsformulierung verwendet.
Im folgenden werden die Ergebnisse der Wirksamkeitstests der Verbindungen gemäss dieser
Erfindung als Agrikulturchemikalien gezeigt.
Testbeispiel 1: Test gegen piricularia oryzae von Reispflanzen (Topf-Test). Reispflanzen (JukkokuArt) werden in Töpfen mit 12 cm Durchmesser kultiviert. Eine Verbindung der vorliegenden Erfindung
in Form des entsprechenden emulgierbaren Konzentrats, das nach der in Arbeitsbeispiel 2
beschriebenen Methode hergestellt wurde? wurde zur vorgeschriebenen Konzentration von 500 ppm
verdünnt. Die Lösung wurde auf Reispflanzen im Sprossstadium aufgesprüht. Dieses Aufsprühen
wurde durchgeführt, indem man die Töpfe auf einem drehbaren Tisch montiert hatte, der sich in
Verbindung mit der aus der Düse der Sprühkanone abgegebenen Chemikalienmenge bewegte. Die
Chemikalienlösung wurde in einer Menge von 50 cm3/ 3 Töpfe, bei einem Druck von 1,5 kg/cm2
aufgesprüht, so dass die Blätter tropfnass wurden.Die so besprühten Reispflanzen wurden am
nächsten Tag in eine Kammer gegeben und dort bei einer relativen Feuchtigkeit von 100 % und einer
Temperatur von 250C zwei Tage lang belassen. In dieser Zeit wurde eine wässrige Sporensuspension
47/612
von gezüchteter piricularia oryzae durch zweimaliges Sprühen zur Infektion der Reispflanzen
aufgebracht.
7 Tage nach der Besprühung wurde der Infektionsgrad von piricularia oryzae pro Topf ausgewertet
und nach dem folgenden Standard eine Gradeinteilung getroffen, die von 0 bis 5 reicht. Gleichzeitig
wurde auch die Phytotoxizität für die Reispflanzen ermittelt.

Testbeispiel 2: Test gegen hypochnus sasakii von Reis (Topf Test). Reispflanzen (Kinmaze-Art)
werden in unglasierten Töpfen mit einem Durchmesser von 12 cm aufgezogen. Auf diese Reispflanzen
wurde bei Beginn des Sprossstadiums eine verdünnte Lösung einer Verbindung gemäss der
vorliegenden Erfindung, die nach dem Testbeispiel 1 hergestellt wurde, aufgesprüht.
Am nächsten Tag wurde das Sclerotium von hypochnus sasakii, welches auf Gerstenkörnern zehn
Tage lang gezüchtet worden war, am Unterteil der Test-Reispflanzen aufgebracht. Die behandelten
Pflanzen wurden in einer Kammer bei einer relativen Feuchtigkeit von 95 % oder mehr und
Temperaturen von 28 bis 300C acht Tage lang stehen gelassen, um die Krankheit sich entwickeln zu
lassen.
Der Grad der Entwicklung dieser Krankheit wurde ausgewertetwird auf Grund des Ausmasses der
Krankheitsflecken vom Fuss der Reispflanzen her, wo die Infektion stattfand, klassifiziert. Die
Schädigungsrate wurde nach der folgenden Formel berechnet: Schädigungsrate = ############## x
100 .
Darin bedeutet N die Gesamtzahl der behandeltenStengel,"0 die Zahl der Stengel, an denen keine
Entwicklung der Krankheit beobachtet werden konnte,nl die Zahl derStengel, auf welchen die
Krankheit bis zur erstenBlattscheide vom Boden her beobachtet wurde, n2 die Zahl der Stengel, auf
denen die Entwicklung der Krankheit vom Boden bis zur zweiten Blattscheide Blattscheide beobachtet
wurde und n3 die Zahl der Stengel, auf denen die Entwicklung der Krankheit vom Bo- den bis zur
dritten Blattscheide beobachtet werden konnte.

Description of DE2022524
Fungizides und herbizides Mittel für Acker- und Gartenbauzwecke
Die Erfindung bezieht sich auf fungizide und herbizide Mittel für Acker- und Gartenbauzwecke, die
dadurch gekennzeichnet sind, dass sie organische Phosphorsäureester der allgemeinen Formel
EMI2.1
worin R1 und R2 je einen Alkylrest mit 1 bis 6 Kohlenstoffatomen 6der einen Cycloalkylrest mit 1 bis
6 Kohlenstoffatomen, X ein Sauerstoff- oder Schwefelatom, Z ein Wasserstoffatom oder einen
Methylrest und Y-einen Aralkylrest oder einen Rest der allgemeinen Formel
EMI2.2
worin W ein Wasserstoff- oder Halogenatom oder einen Nitro- oder einen Alkylrest mit 1 bis 4 CAtomen bedeutet, als wirksamen Bestandteil enthalten.
Bisher wurden Verbindungen mit einem Gehalt an Schwermetallen, diefür Menschen und Haustiere
schädlich sind, wie z.B. organische Quecksilberverbindungen und organische Arsenverbindungen, auf
breiter Basis angewendet, vor allem zur Bekämpfung ernster Reiskrankheiten, wie hypochnus sasakii
und piricularia oryzae, sowohl wegen ihrer ausgezeichneten fungiziden Wirkung als auch aus
ökonomischen Gründen.
Vor kurzem jedoch wurde die Verwendung von organischen Quecksilberverbindungen als
Ackerbauchemikalien während der Wachstumsperiode der Reispflanzen aus Gründen der öffentlichen
Gesundheit verboten, da diese eine direkte bzw. indirekte Toxizität gegenüber dem menschlichen
Körper aufweisen. Dementsprechend war die Entwicklung von billigen Chemikalien, die sowohl
wirkungsvoll auf die oben erwähten Reiskrankheiten sind als auch weniger toxisch auf Mensch und
Haustier wirken, dringend erforderlich.
Es wurde gefunden, dass organische Phosphorsäureester der alLgemeinen Formel
EMI2.3
51/612
worin R1 und R2 jeweils einen Alkylrest mit 1 bis 6 C-Atomen oder einen Cycloalkylrest mit 1 bis 6
C-Atomen, X ein Sauerstoff- oder Schwefelatom, Z ein Wasserstoffatom oder einen Methylrest und Y
einen Aralkylrest oder einen Rest der allgemeinen Formel
EMI3.1
worin W ein Wasserstoff- oder Halogenatom, einen Nitro- oder einen Alkylrest mit 1 bis 4 C-Atomen
und n die Zahlen 1 oder 2 darstellt, bedeuten, fungizide und herbizide Wirkungen aufweisen.
Als Ergebnis weiterer Studien wurde überraschend gefunden, dass Verbindungen der allgemeinen
Formel1, welche Derivate der Verbindungen der allgemeinen Formel II sind, also Verbindungen, die
man durch Transformation des Thioäthers der Verbindung II in den Sulfoxid-Typ der Verbindung I
erhält, stärkere fungizide und herbizide Wirkungen besitzen.
Die vorliegende Erfindung betrifft Verbindungen der allgemeinen Formel1 mit fungiziden und
herbiziden Eigenschaften, Kompositionen, die diese Verbindungen als wirksamen Bestandteil enthalten
sowie die Verfahren zum Schutz von Kulturpflanzen gegen Krankheiten und Unkräuter unter
Verwendung dieser Kompositionen.
Verbindungen gemäss der vorliegenden Erfindung sind bei der Bekämpfung von Pflanzenkrankheiten,
die durch verschiedene Pilzarten, wie Archymyceten,Phycomyceten, Ascomyceten, Basidiomyceten
und Fungi imperfecti hervorgerufen werden, wirksam. Insbesondere Verbindungen, die Substituenten
wie Methyl, äthyl, n-Propyl,i-Propyl, n-Butyl, i-Butyl,sec.-Butyloder Cyclohexylreste für R1 bzw.R2,
Sauerstoff und Schwefel für X, Wasserstoff oder den Methylrest für Z, den Benzylrest, Phenylrest,
chlor-, methyl-, äthyl-, n-propyl-, i-propyl-, n-butyl-,i-butyl-, sec.butyl- oder nitro-substituierten
Benzyl- oder Phenylrest für Y in der allgemeinen Formel I aufweisen, haben hervorragende fungizide
Wirkung, speziell bei der Bekämpfung von schweren Krankheiten der Reispflanze, wie z.B. piricularia
oryzae,cocbliobolus mVabeanus und hypochnus sasakii,
Die Verbindungen gemäss der vorliegenden Erfindung zeigen ihre ausgezeichnete Wirkung auch in
Form herbizider Kompositionen. Sie zeigen sehr gute selektive herbizide Wirkung, wenn gewisse
Mengen vor dem Keimen des Unkrautes auf den Boden aufgebracht werden.Diese Verbindungen
werden sehr wirkungsvoll bei der Bekämpfung von Unkraut jeglicher Art in den Reisfeldern, wie von
Unkräutern der Familie Graminae, von breitblättrigen und von mehrjährigen Unkräutern verwendet,
ohne dass sie irgendeine Phytotoxizität für die Kulturpflanzen, speziell die Reispflanzen, zeigen.
Diese Verbindungen töten alles Unkraut, zeigen dann aber keinen selektiven herbiziden Effekt, wenn
sie in grossen Mengen angewendet werden. Der Ausdruck "Unkraut" bezieht sich im weitesten Sinne
auf alle Pflanzen, die an Stellen wachsen, wo sie unerwünscht sind.
Die Verbindungen gemäss der vorliegenden Erfindung besitzen ein weites Spektrum von guten
biologischen Wirkungen. Sie können bei der Bekämpfung von Pflanzenkrankheiten, speziell
Krankheiten von Reispflanzen, wie oben erwähnt, eingesetzt werden, wenn sie als Fungizide dienen
sollen, aber sie können ebenso'zur Bekämpfung von Unkraut in Reisfeldern verwendet werden, wenn
sie gemäss einer anderen Anwendungsmethode verwendet werden. Diese Verbindungen haben vom
Standpunkt der Wirtschaftlichkeit der im agrarischen Produktionsbereich nötigen Arbeit grossen
praktischen Wert, wie auch infolge ihrer produktionssteigernden Wirkung. Ausserdem haben diese
Verbindungen den grossen Vorteil als Ackerbauchemikalien, da sie keine Schwierigkeiten bezüglich
der Resttoxizität von Anbauprodukten bereiten, zumal sie keine schädlichen Schwermetalle wie die
oben genannten Quecksilberverbindungen enthalten.
Beispiel für Verbindungen gemäss der Erfindung sind in der folgenden Tabelle 1 angeführt: T a b e l

Diese Verbindungenkönnenerfindungsgemäss leicht nach einem Verfahren, das durch das folgende
Reaktionsschema charakterisiert wird, hergestellt werden:
EMI8.1
worinRl, R2, X, Y und Z dieselbe Bedeutung, wie in der allgemeinen Formel I besitzen.
Die Reaktion wird in niedrigen aliphatischen Carbonsäuren z.B.
in Essigsäure, vorzugsweise unter Anwendung eines säurebindenden Mittels, z.B. einer 30 bis 40 eigen
wässrigen Wasserstoffperoxidlösung, durchgeführt. Obwohl diese Reaktion in einem verhältnismässig
weiten Temperaturbereich durchgeführt werden kann, ist es von Vorteil, die Umsetzung zwischen 0
und50 C vorzunehmen.
Als weitere Methoden, die Phosphorsäureester des Sulfoxidtyps herzustellen, seien die folgenden
Verfahren aufgezählt:
1. Sobald die erforderliche Menge eines Halogens zu der wässrigmethanolischen Lösung, die den
Phosphorsäureester enthält, zugegeben wird, bildet sich ein entsprechender Sulfoxidester.
2. Ein Phosphorsäureester, der in Wasser suspendiert ist (ohne Verwendung eines Lösungsmittels)
wird mit der erforderlichen Menge Halogen-Hypochlorit oder -Hypobromit oxidiert.
3. Ein Phosphorsäureester, der in Wasser unlöslich ist, wird in einem geeigneten Lösungsmittel gelöst.
Dazu wird die erforderliche Menge Wasser und säurebindendes Mittel zugegeben und danach die
erforderliche Menge Halogen.
54/612
Als oxidierende Substanzen sind speziell Chlor und Brom wirksam, obwohl auch allgemeine
oxidierende Substanzen, wie Wasserstoffperoxid verwendet werden können. Als säurebindende Mittel
eignen sich Alkalicarbonate, Alkaliacetate und Alkalicyanate. Als Lösungsmittel eignen sich
chloriertes Methylen, Tetrachlorkohlenstoff, chloriertesäthylen und Tetrachloräthylen.
Die so erhaltenen Phosphorsäureester des Sulfoxidtyps sind in Wasser leicht löslich, während die
Thionophosphorsäreester des Sulfoxidtyps in Wasser nur schwer löslich sind.
Im folgenden sind einige experimentelle Beispiele zur Erläuterung des Verfahrens zur Herstellung der
erfindungsgemässen Ver- bindungen angeführt:
Experimentelles Beispiel 1:
EMI9.1
17,5 gO,O-Diisoptopyl-S- (phenylthio)äthyl~/phosphordi- thioat werden in 60 ml Eisessig gelöst.7,5
g 30%iges wässriges Hydrogenperoxid wird dann tropfenweise unter Rühren zugegeben, wobei die
Temperatur der Reaktionsmischung unter 30 C gehalten wird.
Das Rühren wird dann noch 2 Stunden bei Raumtemperatur fortgesetzt, nachdem das
Wasserstoffperoxid zugegeben wurde. 200 ml Wasser wur- den dann zu der Reaktionsmischung
zugegeben und die sich dabeibil- dende ölige Schicht abgetrennt. Das Öl wurde dann inlOO ml
BenzOl gelöst und nacheinander mit Wasser, 1%iger Natriumcarbonatlösung und Wasser gewaschen
und dann über wasserfreiem Natriumsulfat getrocknet. Nach dem Abdampfen des Benzols wurden 14,7
g farbloses O,O-Diisopropyl-S-[-(phenylsulphinyl)äthyl]phosphordithioat erhalten.n2D0= 1,5612.
Wenn diese Verbindungen erfindungsgemäss als Agrikulturchemikalien verwendet werden, werden sie
entweder direkt mit Wasser bzw.
in Mischung mit Trägermaterialien verdünnt, und in flüssige Form übergeführt, oder als benetzbare
Pulver, emulgierbare Konzentrate, Stäube, Granulate, Öle, Tabletten, Pasten usw. nachVerfahren, die
bei den herkömmlichen Agrikulturchemikalien angewendet werden, verwendet. Als feste Träger
eignen sich inaktive Mineralmaterialien, wie z.B. Talk, Ton, Kaolin, Montmorillonit, Diatomeenerde,
Calcium carbonat usw., als flüssige Verdünnungsmittel sowohl Lösungsmittel wie auch
Nichtlösungsmittel, in denen die Chemikalien durch Hilfsmittel dispergiert oder gelöst werden, z.B.
Wasser, Alkohole, Benzol, Xylol, Dimethylnaphthalin, aromatischeNaphtha, Dimethylformamid usw.
Sie können, um ihre Wirksamkeit zu sichern, in Mischung mit solchen Hilfsmitteln der
Agrikulturchemie wie Spreitmitteln, Emulgierern, benetzenden Substanzen, adhäsiven Substanzen usw.
angewendet werden. Weiters können sie angewendet werden in Mischung mit Insektiziden,
Akariziden, Nematoziden, z.B. organischen Phosphorverbindungen, Carbamatverbindungen,
Organochlorverbindungen, Dinitroverbindungen, weiters mit Fungiziden, wie
Organophosphorverbindungen,Organoschwefelverbindungen, Dithiocarbamatverbindungen,
Dinitroverbindungen; mit Antibiotika, Herbiziden, wie Phenoxyverbindungen, Carbamatverbindungen,
Harnstoffverbindungen, Triazinverbindungen, Chlorphenolverbindungen, substituierten

Abstract:
Abstract of EP0190105
There is described a selective herbicidal agent which contains, besides inert additives, a) the
herbicidally active sulphonylurea N-(2-methoxycarbonyl-1- phenylsulphonyl)-N'-(bisdifluoromethoxypyrimidin-2-yl)-urea of the formula I and b) to increase the tolerance of the crop, a
non-phytotoxic amount of a dichloroacetamide of the formula II where Ra and Rb independently of one
another are in each case hydrogen, an unsubstituted or substituted alicyclic hydrocarbon radical, or one
of the two radicals is an amine, or the two radicals together with the nitrogen atom to which they are
bonded are also a 5-12-membered heterocyclic radical. The composition is suitable for controlling
weeds in crops of useful plants, for example cereals, maize, rice, millet, etc.Description:
Description of EP0190105
Herbizides Mittel Die Erfindung betrifft ein selektiv wirkendes Mittel, welches als herbiziden
Wirkstoff den SulfonylharnstoffN-(2-Methoxycarbonyl)- phenylsulfonyl-N-(4s6-bisdifllJoromethoxy-pyrimidin-2-yl)-harnstoff der Formel I enthält
EMI1.1
zusammen mit einem antagonistisch wirkenden Amid der Dichloressigsäure (Antidote), der Formel II
EMI1.2
worin Ra undRb unabhängig voneinander je Wasserstoff einen unsubstituierten oder substituierten
alicyclischen Kohlenwasserstoffrest oder eines davon einen Aminorest oder beide zusammen mit dem
Stickstoffatom, an das sie gebunden sind auch einen 5-12-gliedrigen heterocyclischen Rest bedeuten,
welche die Toleranz der Kulturpflanzen gegenüber der phytotoxischen Wirkung erhöht, ohne dass
deswegen die Herbizidwirkung gegenüber den Unkräutern merklich abfällt.Die Erfindung betrifft
ebenfalls die Verwendung dieses Mittels zur Unkrautbekämpfung in Nutzpflanzenkulturen.
Der Sulfonylharnstoff als Herbizid ist bekannt, siehe beispielsweise die EP-A 84 020, ZA 127/83, USP
4,478,635.
61/612
N-(2-MethoxyCarbonyl)phenylsulfonyl-N'-(4,6-bis-difluormethoxy-pyri- midin-2-yl)-harnstoff ist ein
Herbizid mit recht starker Wirkung.
Dies bringt die Gefahr schädigender Ueberdosierung mit sich.
Schadwirkungen sind nicht nur auf Ueberdosierung zurückzuführen, sie können auch auftreten wegen
abnormalen klimatischen Verhältnissen oder wegen Vorbehandlung des Bodens.
Es hat sich deshalb als wünschenswert erwiesen, die Resistenz oder Toleranz der Kulturpflanzen
gegenüber der phytotoxischen Wirkung der Sulfonylharnstoff-Herbizide zu erhalten. Im US Patent No.
4 343 649 wird beschrieben, dass die bekanntenHerbizid-Antidoten 1,8-Naphthalinsäureanhydrid,
N,N-Diallyldichloracetamid sowiea-Cyano-methoxi- imino-2-phenylacetonitril diese Aufgabe
erfüllen, wenn man sie in Nutzpflanzenkulturen gleichzeitig mit-dem Sulfonylharnstoff-Herbizid
verwendet. Hingegen ist die Toleranz dieser bekannten Herbizid Safener-Mischungen speziell in
Maiskulturen für einen praktischen Einsatz ungenügend.
Ueberraschenderweise wurde nun gefunden, dass sich die Toleranz von Kulturpflanzen speziell Mais
gegenüber der phytotoxischen Wirkung des obigen Sulfonylharnstoff-Herbizides stark erhöht, ohne
dass dadurch die Herbizidwirkung auf die Grosszahl der Unkräuter und Ungräser beeinträchtigt wird,
wenn man das Sulfonylharnstoff Herbizid zusammen mit einem Amid der Dichloressigsäure verwendet
welches als Herbizid-Antagonist oder Antidot wirkt.
Die Herstellung desN-(2-Methoxyzarbonylphenylsulfonyl)-N'-(4,6-bis- >; difluormethoxy)-pyrimidin2-yl-harnstoffes der Formel I geschieht nach an sich bekannten Methoden und ist z.B. in der
veröffentlichten Europäischen Patentanmeldung EP-A 84 020 beschrieben.
Man setzt beispielsweise in einem inerten organischen Lösungsmittel 2Methoxycarbonylphenylsulfonylamid mit dem 2-Phenoxycarbamat des 4,6-bis(difluoromethoxy)pyrimidins um gemäss dem Reaktionsschema:
EMI3.1
Ferner kann man ebenfalls in einem inerten organischen Lösungsmittel das 2Methoxycarbonylphenylsulfonylisocyanat mit 2-Amino-4,6bis(difluoromethoxy)pyrimidin umsetzen,
gemäss dem Reaktionsschema
EMI3.2
Ebensogut kann man in einem inerten organischen Lösungsmittel2-Methoxycarbonyl-phenylsulfonamid mit 2-Isocyanato-4,6-bis(difluormehoxy)pyrimidin umsetzen gemäss dem
Reaktionsschema
EMI3.3
Schliesslich kann man in einem inerten organischen Lösungsmittel, das Phenoxycarbamat des 2Methoxycarbonylphenylsulfonamides mit dem2-Amino-4, 6-bis(difluoromethoxy)pyrimidin umsetzt,
gemäss dem Reaktionsschema
EMI3.4
Die Umsetzungen werden vorteilhafterweise in aprotischen, inerten, organischen Lösungsmitteln
vorgenommen wie Methylenchlorid, Tetrahydrofuran, Acetonitril, Dioxan, Toluol.
Die Reaktionstemperaturen liegen vorzugsweise zwischen-20' ; und+1200C. Die Umsetzungen
verlaufen im allgemeinen leicht exotherm und können bei Raumtemperatur durchgeführt werden.
Zwecks Abkürzung der Reaktionszeit oder auch zum Einleiten der Umsetzung wird zweckdienlich für
kurze Zeit bis zum Siedepunkt des Reaktionsgemisches aufgewärmt. Die Reaktionszeiten können
ebenfalls durch Zugabe von äquimolaren oder katalytischen Mengen von Basen verkürzt werden.
Als Basen können sowohl organische Basen wie Amine, wieTriathyl- aminsChinunlidin, Pyridin etc.
als auch anorganische Basen wie Hydride wie Natrium- oder Calciumhydrid, Carbonate wie Natriumund Kaliumcarbonat verwendet werden.
Das Endprodukt kann durch Einengen und/oderVerdpfen des Lösungsmittels isoliert und durch
Umkristallisieren oder Zerreiben des festen Rückstandes in Lösungsmitteln in denen es sich nicht gut
62/612
lösten, wie Aether, aromatischen Kohlenwasserstoffen oder chlorierten Kohlenwasserstoffen gereinigt
werden.
Die Wirkstoffe der Formel I sind stabile Verbindungen. Ihre Handhabung bedarf keiner vorsorglichen
Massnahme.
Die Zwischenprodukte zur Herstellung desN-(2-Methoxycarbonyl-phenyl- sulfonyl-N'-[4,6-bis(difluoromethoxy)pyrimidin-2-yl]-harnstoffes sind bekannt oder können nach bekannten Methoden
hergestellt werden.
Als Gegenmittel oder Antidot zum Sulfonylharnstoff der Formel1 werden erfindungsgemäss Amide
der Dichloressigsäure der Formel II verwendet.
Eine grössere Anzahl dieser Verbindungen sind als Safener oder Antidotes für Herbizide mit anderer
als Sulfonylharnstoff-Struktur beschrieben worden. Solche Herbizide müssen in vielen Fällen in
höheren Aufwandmengen angewendet werden. Ueberraschenderweise hat es sich nun gezeigt, dass sie
auch ganz besonders den Sulfonylharnstoff der Formel I, welcher eine sehr starke herbizide Wirkung
aufweist, kulturspezifisch speziell in Maiskulturen zu antagonisieren vermögen.
Die Verbindungen der Formel II bis XVI sind zum Schützen von Kulturpflanzen gegen die
schädigende Wirkung desSulfonylharn- stoffes geeignet und können daher in bezug auf ihre
Anwendung in Kombination mit dem vorgenannten Herbizid als Gegenmittel,1:Antidote11 oder auch
als "Safener" bezeichnet werden.
Ein solches Gegenmittel oder Antidote kann je nach Anwendungszweck zur Vorbehandlung des
Saatgutes der Kulturpflanze (Beizung des Samens oder der Stecklinge) eingesetzt oder vor oder nach
der Saat in den Boden gegeben werden. Es kann aber auch für sich allein oder zusammen mit dem
Herbizid vor oder nach dem Auflaufen der Pflanzen appliziert werden. Die Behandlung der Pflanze
oder des Saatgutes mit dem Antidote kann daher grundsätzlich unabhängig vom Zeitpunkt der
Applikation der phytotoxischen Chemikalien erfolgen. Die Behandlung der Pflanzen kann jedoch
durch gleichzeitige Applikation des Sulfonamides der Formel I und des Gegenmittels (Tankmischung)
erfolgen. Die preemergente Behandlung schliesst sowohl die Behandlung derAnbaufläche vor der
Aussaat (ppi- pre plant incorporation) als auch die Behandlung der angesäten, aber noch nicht
bewachsenen Anbauflächen ein.
Die Aufwandmengen des Gegenmittels im Verhältnis zum Herbizid richten sich weitgehend nach der
Anwendungsart. Bei einer Feldbehandlung, bei der Herbizid und Gegenmittel entweder gleichzeitig
(Tankmischung) oder separat appliziert werden, liegt das Verhältnis der Mengen von Gegenmittel zu
Herbizid im Bereich von 1:100 bis 5:1.
In der Regel wird bei einem Mengenverhältnis von Gegenmittel zu Herbizid von 1:5 bis 1:50 die volle
Schutzwirkung erreicht. Bei der Samenbeizung und ähnlichen gezielten Schutzmassnahmen werden
jedoch weit geringere Mengen Gegenmittel im Vergleich mit den später pro Hektar Anbaufläche
verwendeten Mengen an Herbizid benötigt. Im allgemeinen werden bei der Samenbeizung pro kg
Samen 0,1 - 10 g Gegenmittel benötigt. In der Regel wird mit 0,1 - 5 g Gegenmittel pro kg Samen
bereits die volle Schutzwirkung erreicht. Falls das Gegenmittel kurz vor der Aussaat durch
Samenquellung appliziert werden soll, so werdenzweckmässig Lösungen des Gegenmittels verwendet,
welche den Wirkstoff in einer Konzentration von 1 - 10'000 ppm enthalten. In der Regel wird mit
Konzentrationen des Gegenmittels von 100 - 1'000 ppm die volle Schutzwirkung erreicht.
-In der Regel liegt zwischen protektiven Massnahmen, wie Samenbeizung und Behandlung von
Stecklingen mit einem Gegenmittel der Formel II und der möglichen späteren Feldbehandlung mit
Agrarchemikalien ein längerer Zeitraum. Vorbehandeltes Saat- und Pflanzengut kann später in der
Landwirtschaft, im Gartenbau und in der Forstwirtschaft mit unterschiedlichen Chemikalien in
Berührung kommen.
Erfindungsgemässe Mittelkönnen gegebenenfalls zusätzlich jene Agrarchemikalien enthalten, vor
deren Einfluss die Kulturpflanze geschützt werden soll.
63/612
Als Kulturpflanzen gelten im Rahmen vorliegender Erfindung alle Pflanzen, die in irgendeiner Form
Ertragsstoffe, wie Samen, Wurzeln, Stengel, Knollen, Blätter, Blüten, ferner Inhaltsstoffe, wie Oele,
Zucker, Stärke, Eiweiss usw., produzieren und zu diesem Zweck angebaut werden. Zu diesen Pflanzen
gehören beispielsweise sämtliche Getreidearten, wie Weizen, Roggen, Gerste und Hafer, daneben vor
allem Reis, Kulturhirse, Mais, Baumwolle, Zuckerrüben, Zuckerrohr, Soja, Bohnen und Erbsen.
Das Gegenmittel kann überall dort eingesetzt werden, wo eine Kulturpflanze der vorgenannten Art vor
der phytotoxischen Wirkung desN-(2-Methoxyearbonylphenylsulfonyl)-N'-(4,6-bis-difluoromethoxypyrimidin-2-yl-harnstoffes der Formel I geschützt werden soll.
Als Antogonisten oder Gegenmittel werden erfindungsgemäss Dichloracetamide entsprechend der

Die Verbindungen der Formel II sindgrösstenteils aus der Literatur bekannt oder können nach
bekannten Methoden hergestellt werden.
Die Dichloramide der Formel II werden z.B. hergestellt, indem man ein Dichloressigsäurehalid, z.B.
das Chlorid oder Bromid in einem inerten organischen Lösungsmittel, mit einem Amin der
FormelHNR ,Rb umsetzt entsprechend dem Reaktionsschema
EMI12.1
Ac steht für ein Halogenatom oder einen Rest -OCOCHClz.
Die Reaktion wird zweckmässigerweise in einem reaktionsinerten Lösungsmittel bei Normaldruck
durchgeführt. Als Lösungsmittel eignen sich beispielsweise aliphatische oder aromatische
Kohlenwasserstoffe wie Benzol, Toluol, Xylole, Cyclohexan, Petroläther; halogenierte
Kohlenwasserstoffe wie Chlorbenzol, Methylenchlorid, Aethylenchlorid, Chloroform; Aether
undätherartige Verbindungen wie Diäthyläther, Diisopropyläther, t-Butylmethyläther,Dimethoxyäthan,
Dioxan, Tetrahydrofuran, Anisol; Ketone wie Aceton, Methyläthylketon; Ester wie Aethylacetat,
Butylacetat und Gemische solcher Lösungsmittel untereinander.
Als säurebindende Mittel sind Basen, insbesondere tertiäre Amine wie Trimethylamin, Triäthylamin,
Chinuclidin,1,4-Diazabicyclo-(2,2,2)- octan, 1,5-Diazabicyclo(4,3,0)non-5-en oder 1,5Diazabicyclo(5,4,0)undec-7-en geeignet. Es können aber auch anorganische Basen wie Hydride wie
Natrium- oder Calciumhydrid, Hydroxide wie Natrium- und Kaliumhydroxid, Carbonate wie Natriumund Kaliumcarbonat oder Hydrogencarbonate wie Kalium- oder Natriumhydrogencarbonat verwendet
werden.
Die Dichloracetamide der Formel II sind grösstenteils bekannt und in vielen Publikationen beschrieben.
Sie können nach bekannten Methoden hergestellt und entsprechend ihrer chemischen Struktur
verschiedenen Untergruppen zugeordnet werden: Eine erste Gruppe wird durch die Verbindungen der
Formel II verkörpert,

Wirkung vonN-( 2-Methoxycarbonylphenylsulfonyl)- N'-(4',6'-bis-difluormethoxypyrimidin-2-yl)harnstoff zu schützen, wurde gemäss Beispiel 1 geprüft. Die Resultate sind in der Tabelle la
zusammengefasst.
Beispiel 1: Tankmischung Vorauflauf in Mais Plastiktöpfe (oberer Durchmesser 11 cm. Inhalt 500
ccm) werden mit sandig toniger Lehmerde gefüllt. Acht Maissamen der Sorte 'LG-11' werdeneingesät
und mit Erde bedeckt und anschliessend angegossen.
Die Testpflanzen werden im Gewächshaus kultiviert und im 2- bis 3-Blattstadium mit den
Prüfsubstanzen behandelt. Die als Safener zu prüfende Substanz wird in Wasser gelöst und zusammen
mit dem Herbizid der Formel I in der gegebenen Aufwandmenge auf die Pflanzen gesprüht. 21 Tage
nach der Applikation wird die Schutzwirkung des Safeners in Prozent bonitiert. Als Referenz dienen
dabei mit Herbizid allein behandelte Pflanzen (keine Schutzwirkung) sowie die vollständig
unbehandelte Kontrolle (100X Wachstum). Die Resultate sind in der Tabelle la zusammengefasst.

In einem 750 ml Vierhalskolben gibt man 126 gN-(3,4-Dimethoxy- benzyl)-N-isopropyl-amin
(dargestellt durch hydrierende Kondensation von 3,4-Dimethoxy-benzaldehyd mit Isopropylamin, Kp.
77,5 -78,5 /0,03 mbar) und 250 ml Toluol undrührt bis sich das Amin gelöst hat. Dazu gibt man 120 g
20 %ige Natronlauge und rührt unter Kühlen des Kolbens in Alkohol/CO2-Bad bis die Temperatur der
Reaktionslösung-100 bis-150C beträgt. Dann tropft man langsam in die gerührte Aminlösung eine
solche von 89 g Dichloressigsäurechlorid in 100ml Toluol. Dabei fällt sofort ein weisser Niederschlag
aus.
Nachdem alles zugetropft ist, was ca. 1 1/2 Stunden in Anspruch nimmt, wird das Kühlbad
weggenommen und das Reaktionsgemisch weitergerührt, bis es Raumtemperatur erreicht. Dann wird
auf Eis/Wasser gegossen und die organische Phase im Scheidetrichter mit Toluol extrahiert. Die
Toluolphasen werden gesammelt, je zweimal mit 1 N Salzsäure und Wasser gewaschen, getrocknet und
eingedampft. Es verbleiben 176 g(91,7 % der Theorie) Titelprodukt als helles zähes Oel mit
BrechungsindexnD22 1.5495, welches schliesslich erstarrt.

20%ige Natronlauge und rührt unter Kühlen des Kolbens inAlkoholJCOz-Bad bis die Temperatur der
Reaktionslösung-100 bis-150C beträgt. Dann tropft man langsam in die gerührte Aminlösung eine
solche von 14,8 g Dichloressigsäurechlorid in 10 ml Toluol. Dabei fällt sofort ein weisser Niederschlag
aus.
Nachdem alles zugetropft ist, was ca. 1112 Stunde in Anspruch nimmt, wird das Kühlbad
weggenommen und das Reaktionsgemisch weitergerührt, bis es Raumtemperatur erreicht. Dann wird
aufEis/Wasser gegossen und die organische Phase im Scheidetrichter mit Toluol extrahiert. Die
Toluolphasen werden gesammelt, je zweimal mit 1 N Salzsäure und Wasser gewaschen, getrocknet und
eingedampft. Es verbleiben 20,6 g Titelprodukt als helles zähes Oel.

In einem Sulfierkolben wird eine Lösung von 22,3 g N-(3,4-phenyläthyl)-N-isopropyl-amin vorgelegt.
Dazu gibt man unter Rühren 20 ml 20%ige wässrige Natronlauge. Dann wird das Reaktionsgemisch
mit einem Kühlbad auf eine Temperatur von-10 bis-150 gekühlt, zu dem man unter Rühren langsam
eine Lösung der berechneten Menge Dichloracetylchlorid in 10 ml Toluol tropft. Nachdem alles
zugegeben ist, nimmt man das Kühlbad weg und rührt während 2 Stunden bei Raumtemperatur weiter.
Dann wird das Reaktionsgemisch auf EislWasser gegossen, mit Toluol extrahiert und die gesammelten
organischen Phasen je einmal mit verdünnter Natronlauge, verdünnter Salzsäure und zweimal mit
Wasser gewaschen, über Natriumsulfat getrocknet und am Rotationsverdampfer eingedampft. Man

TECHNICAL FIELD
[0001] The present invention relates to aromatic diamide derivatives or salts thereof; an agricultural
and horticultural chemical, in particular, an agricultural and horticultural insecticide, which contains
said compound as an active ingredient; and a usage of the chemical.

BACKGROUND ART
[0002] JP-A-11-240857 discloses a compound analogous to the aromatic diamide derivative of the
present invention but does not describes working examples, physical properties and the like with
respect to the compound of the present invention.
DISCLOSURE OF THE INVENTION
[0003] The production of agricultural and horticultural crops and the like is still badly damaged by
insect pests and the like, and the development of a novel agricultural and horticultural chemical, in
particular, agricultural and horticultural insecticide is desired because of, for example, the appearance
of insect pests resistant to existing chemicals. In addition, because of the increased population of aged
farmers, and the like, various labor-saving application methods are desired and the development of an
agricultural and horticultural chemical having properties suitable for the application methods is desired.
[0004] The present inventors earnestly investigated in order to develop a novel agricultural and
horticultural chemical, and consequently found that the aromatic diamide derivative represented by the
general formula (I) of the present invention is a novel compound not known in any literature, and the
present inventors found a novel use of said derivative as an agricultural and horticultural chemical, in
particular, an agricultural and horticultural insecticide and their effective usage, whereby the present
invention has been accomplished.
[0005] That is, the present invention relates to an aromatic diamide derivative represented by the
general formula (I):

wherein R>;1;, R>;2;, R>;3;, A>;1;, B, Q>;1; through Q>;5;, X, n, Y, m, Z>;1; and Z>;2; are as
defined above.
[0013] An aromatic diamide derivative of the general formula (I-1) can be obtained by allowing an
aromatic carboxylic acid anhydride derivative of the general formula (II) to react with an aromatic
amine of the general formula (III) in the presence of an inert solvent to obtain an aromatic imide
derivative of the general formula (IV), and allowing said aromatic imide derivative (IV) to react with
an amine of the general formula (V) after or without isolation of the aromatic imide derivative (IV).

[0014] As the inert solvent usable in this reaction, any inert solvent may be used so long as it does
not markedly inhibit the progress of the reaction. There can be exemplified inert solvents including
aromatic hydrocarbons such as benzene, toluene, xylene, etc.; halogenated hydrocarbons such as

dimethylacetamide, etc.; acids such as acetic acid, etc.; dimethyl sulfoxide; 1,3-dimethyl-2imdazolidinone; and the like. These inert solvents may be used singly or as a mixture thereof.
[0015] Since the reaction is an equimolar reaction, it is sufficient that the reactants are used in
equimolar amounts, though either of them may be used in excess. If necessary, the reaction may be
carried out under dehydrating conditions.
[0016] As to the reaction temperature, the reaction can be carried out at room temperature to the
reflux temperature of the inert solvent used. Although the reaction time is varied depending on the
scale of reaction, the reaction temperature, etc., it may be properly chosen in the range of several
minutes to 48 hours.

[0017] After completion of the reaction, the desired compound is isolated from the reaction system
containing the desired compound by a conventional method, and if necessary, purified by
recrystallization, column chromatography, etc., whereby the desired compound can be produced. The
desired compound can be subjected to the subsequent reaction step without isolation from the reaction
system.
[0018] The aromatic carboxylic acid anhydride derivative of the general formula (II) can be produced
by any of the processes described in J. Org. Chem., 52, 129 (1987), J. Am. Chem. Soc., 51, 1865 (1 to
29), ditto 63, 1542 (1941), etc. The aromatic amine of the general formula (III) can be produced by any

[0020] Since the reaction is an equimolar reaction, it is sufficient that the reactants are used in
equimolar amounts, though the amine of the general formula (V) may be used in excess.
[0021] As to the reaction temperature, the reaction can be carried out at room temperature to the
reflux temperature of the inert solvent used. Although the reaction time is varied depending on the
scale of reaction, the reaction temperature, etc., it may be properly chosen in the range of several
minutes to 48 hours.
[0022] After completion of the reaction, the desired compound is isolated from the reaction system
containing the desired compound by a conventional method, and if necessary, purified by
recrystallization, column chromatography, etc., whereby the desired compound can be produced.

wherein R>;1;, R>;2;, R>;3;, A>;1;, B, Q>;1; through Q>;5;, X, n, Y, m, Z>;1; and Z>;2; are as
defined above.
[0024] An aromatic diamide derivative of the general formula (I) can be produced by allowing an
aromatic carboxylic acid anhydride derivative of the general formula (II-1) to react with an amine of
the general formula (V) in the presence of an inert solvent to obtain a phthalamide of the general
formula (VI-2), and treating this aromatic amide (VI-2) as follows after or without isolation. When
R>;2; of the aromatic amide (VI-2) is a hydrogen atom, the aromatic amide (VI-2) is subjected to
condensation reaction in the presence of a condensing agent to obtain a compound of the general
formula (VII-2), which is allowed to react with an aromatic amine of the general formula (III-1) in the
presence of an inert solvent after or without isolation of the compound (VII-2). When R>;2; of the
aromatic amide (VI-2) is other than a hydrogen atom, the aromatic amide (VI-2) is condensed with an
aromatic amine of the general formula (III-1) in the presence of a condensing agent.
[0025] Alternatively, an aromatic diamide derivative of the general formula (I) can be produced by
allowing an aromatic carboxylic acid anhydride derivative of the general formula (II-1) to react with an
aromatic amine of the general formula (III-1) in the presence of an inert solvent to obtain an aromatic
amide of the general formula (VI-1), and treating the aromatic amide (VI-1) as follows after or without
isolation. When R>;3; of the aromatic amide (VI-1) is a hydrogen atom, the aromatic amide (VI-1) is
subjected to condensation reaction in the presence of a condensing agent to obtain a compound of the
98/612
general formula (VII-1), which is allowed to react with an amine of the general formula (V) in the
presence of an inert solvent after or without isolation of the compound (VII-1). When R>;3; of the
aromatic amide (VI-1) is other than a hydrogen atom, the aromatic amide (VI-1) is condensed with an
amine of the general formula (V) in the presence of a condensing agent.
(1). General formula (II-1) -; general formula (VI-1), or general formula (II-1) -; general formula (VI2)

similar to that described in production process 1-(2).
(2). General formula (VII-1) or general formula (VII-2) -; general formula (I)
[0027] In the case of this reaction, the desired compound can be produced in a manner similar to that
described in production process 1-(2).
(3). General formula (VI-1) -; general formula (VII-1), or general formula (VI-2) -; general formula
(VII-2)
[0028] In the case of either of these reactions, the desired compound can be produced according to
the process described in J. Med. Chem., 10, 982 (1967).
(4). General formula (VI-1) or general formula (VI-2) -; general formula (I)
[0029] The desired compound can be produced by allowing an aromatic amide derivative of the
general formula (VI-1) or the general formula (VI-2) to react with an amine of the general formula (V)
or the general formula (III-1), respectively, in the presence of a condensing agent and an inert solvent.
If necessary, the reaction can be carried out in the presence of a base.
[0030] The inert solvent used in the reaction includes, for example, tetrahydrofuran, diethyl ether,
dioxane, methylene chloride and chloroform.
[0031] As the condensing agent used in the reaction, any condensing agent used in conventional
amide production may be used. There can be exemplified Mukaiyama reagent (2-chloro-Nmethylpyridinium iodide), DCC (1,3-dicyclohexylcarbodiimide), CDI (carbonyldiimidazole) and
DEPC (diethyl cyanophosphate). As to the amount of the condensing agent used, the condensing agent
may be used in an amount properly chosen in the range of 1 mole to excess moles per mole of the
aromatic amide derivative of the general formula (VI-1) or the general formula (VI-2).
[0032] The base usable in the reaction includes, for example, organic bases such as triethylamine,
pyridine, etc., and inorganic bases such as potassium carbonate, etc. As to the amount of the base used,
the base may be used in an amount properly chosen in the range of 1 mole to excess moles per mole of
the aromatic amide derivative of the general formula (VI-1) or the general formula (VI-2).
[0033] As to the reaction temperature, the reaction can be carried out at 0 DEG C to the boiling point
of the inert solvent used. Although the reaction time is varied depending on the scale of reaction, the
reaction temperature, etc., it ranges from several minutes to 48 hours.
[0034] After completion of the reaction, the desired compound is isolated from the reaction system
containing the desired compound by a conventional method, and if necessary, purified by
recrystallization, column chromatography, etc., whereby the desired compound can be produced.

[0038] The agricultural and horticultural chemical, in particular, agricultural and horticultural
insecticide, which contains as an active ingredient the aromatic diamide derivative of the general
formula (I) or salt thereof of the present invention has a marked insecticidal effect on the aboveexemplified insect pests injurious to paddy field crops, upland crops, fruit trees, vegetables, other
crops, flowers and ornamental plants, and the like. Therefore, the desired effect of the agricultural and
horticultural chemical, in particular, agricultural and horticultural insecticide of the present invention
can be obtained by applying the agricultural and horticultural chemical to the paddy field water, stalks
and leaves of fruit trees, vegetables, other crops, flowers and ornamental plants, soil, etc., at a season at
which the insect pests are expected to appear, before their appearance or at the time when their
appearance is confirmed.
[0039] The agricultural and horticultural chemical of the present invention is generally prepared into
conveniently usable forms according to an ordinary manner for preparation of agrochemicals.
[0040] That is, the aromatic diamide derivative of the general formula (I) or a salt thereof and,
optionally, an adjuvant are blended with a suitable inert carrier in a proper proportion and prepared into
a suitable preparation form such as a suspension, emulsifiable concentrate, soluble concentrate,
wettable powder, granules, dust, tablets or the like through dissolution, dispersion, suspension, mixing,
impregnation, adsorption or sticking.
104/612
[0041] The inert carrier usable in the present invention may be either solid or liquid. As a material
usable as the solid carrier, there can be exemplified soybean flour, cereal flour, wood flour, bark flour,
saw dust, powdered tobacco stalks, powdered walnut shells, bran, powdered cellulose, extraction
residue of vegetables, powdered synthetic polymers or resins, clays (e.g. kaolin, bentonite, and acid
clay), talcs (e.g. talc and pyrophyllite), silica powders or flakes (e.g. diatomaceous earth, silica sand,
mica and white carbon [synthetic, high-dispersion silicic acid, also called finely divided hydrated silica
or hydrated silicic acid, some of commercially available products contain calcium silicate as the major
component]), activated carbon, powdered sulfur, pumice, calcined diatomaceous earth, ground brick,
fly ash, sand, calcium carbonate, calcium phosphate and other inorganic or mineral powders, chemical
fertilizers (e.g. ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and ammonium
chloride), and compost. These carriers may be used alone or as a mixture thereof.
[0042] A material usable as the liquid carrier is selected from materials that have solubility in
themselves or which are without such solubility but are capable of dispersing an active ingredient with
the aid of an adjuvant. The following are typical examples of the liquid carrier and can be used alone or
as a mixture thereof: water, alcohols (e.g. methanol, ethanol, isopropanol, butanol and ethylene glycol),
ketones (e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone and
cyclohexanone), ethers (e.g. ethyl ether, dioxane, Cellosolve, dipropyl ether and tetrahydrofuran),
aliphatic hydrocarbon (e.g. kerosene and mineral oils), aromatic hydrocarbons (e.g. benzene, toluene,
xylene, solvent naphtha and alkylnaphthalenes), halogenated hydrocarbons (e.g. dichloroethane,
chloroform, carbon tetrachloride and chlorobenzene), esters (e.g. ethyl acetate, diisopropyl phthalate,
dibutyl phthalate and dioctyl phthalate), amides (e.g. dimethylformamide, diethylformamide and
dimethylacetamide), nitriles (e.g. acetonitrile), and dimethyl sulfoxide.
[0043] The following are typical examples of the adjuvant, which are used depending upon purposes
and used alone or in combination is some cases, or need not to be used at all.
[0044] To emulsify, disperse, dissolve and/or wet a compound as active ingredient, a surfactant is
used. As the surfactant, there can be exemplified polyoxyethylene alkyl ethers, polyoxyethylene
alkylaryl ethers, polyoxyethylene higher fatty acid esters, polyoxyethylene resonates, polyoxyethylene
sorbitan monolaurate, polyoxyethylene sorbitan monooleate, alkylarylsulfonates, naphthalene sulfonic
acid condensation products, ligninsulfonates and higher alcohol sulfate esters.
[0045] Further, to stabilize the dispersion of a compound as active ingredient, tackify it and/or bind
it, the adjuvants exemplified below may also be used, namely, there may also be used adjuvants such as
casein, gelatin, starch, methyl cellulose, carboxymethyl cellulose, gum arabic, poly(vinyl alcohol)s,
turpentine, bran oil, bentonite and ligninsulfonates.
[0046] To improve the flowability of a solid product, the following adjuvants may also be used,
namely, there may be used adjuvants such as waxes, stearates, alkyl phosphates, etc.
[0047] Adjuvants such as naphthalenesulfonic acid condensation products and polycondensates of
phosphates may be used as a peptizer for dispersible products.
[0048]
Adjuvants such as silicone oils may also be used as a defoaming agent.
[0049] The content of the compound as active ingredient may be varied as required, and the
compound as active ingredient may be used in a proportion properly chosen in the range of 0.01 to 90
parts by weight per 100 parts of the agricultural and horticultural insecticide. For example, in dusts or
granules, the suitable content of the compound as active ingredient is from 0.01 to 50 % by weight. In
emulsifiable concentrates or flowable wettable powders, it is also from 0.01 to 50 % by weight.
[0050] The agricultural and horticultural chemical, in particular, agricultural and horticultural
insecticide of the present invention is used to control a variety of insect pests in the following manner:
it is applied to a crop on which the insect pests are expected to appear, or a site where appearance or
growth of the insect pests is undesirable, as it is or after being properly diluted with or suspended in
water or the like, in an amount effective for control of the insect pests.
105/612
[0051] The applying dosage of the agricultural and horticultural insecticide of the present invention is
varied depending upon various factors such as a purpose, insect pests to be controlled, a growth state of
a plant, tendency of insect pests appearance, weather, environmental conditions, a preparation form, an
application method, an application site and application time. It may be properly chosen in the range of
0.001 g to 10 kg, preferably 0.01 g to 1 kg, (in terms of the compound as active ingredient) per 10 ares
depending upon purposes.
[0052] The agricultural and horticultural chemical, in particular, agricultural and horticultural
insecticide of the present invention may be used in admixture with other agricultural and horticultural
insecticides, acaricides, nematicides, fungicides, biotic pesticides or the like in order to expand both
spectrum of controllable insect pest species and the period of time when effective application are

COMPLETE SPECIFICATIONPhosphorus-Containing Pesticides
We, VEBFARBENFABRIK WOLFENA of
Wolfen Kreis Bitterfeld, Germany, aCorpera- tion organised under the laws of Eastern Germany, do
hereby declare the invention, for which we pray that a patent may be granted to us, and the method by
which it is to be performed, to be particularly described in and by the followingstatement:
The present invention is concerned with new phosphorus-containing pesticides and with the
production thereof.
In the literature there are described various reactions of esters of trivalent phosphorus with sulphur
halides. Thus, for example, dialkyl phosphites react with sulphur chlorides to give bis - (dialkyl phosphoryl) - sulphides (see
German Patent Specification No. 820,001) or to give the corresponding disulphides (see
Ettel and M. Zbirovski, Chem. Listy,50, 12614/1956; U.S. Patent Specification No.
2,630,450)
Tetraalkyl thiopyrophosphates, i.e. compounds of the general formula[(RO)2PO!]2S, together with
other products, are formed from triallyl phosphites and sulphur chlorides, the intermediate formation of
asulphenyl chlorides being assumed (see J.Michalski et al., Chem.
128/612
and Ind., 1052/1962; A. C. Poshkus and J. E.
Herweh, J.A.C.S., 84, 555/1962; Chem. and
Ind., 1316/1961).
We have now found, surprisingly, that esters of pentavalent phosphorus of the general formula:
2 (RO),P = S + S,Cl, >; ;
Because of the thermal lability of the reaction products, they cannot be purified by distillation. The
inertness of sulphur-free esters of pentavalent phosphorus leads one to the assumption that the abovementioned reaction proceeds viasulphenyl chlorides or thiosulphenyl chlorides.
Paper chromatographic investigations shew that the reaction products consist of a mixture of various
phosphoric acid esters whichprobEMI1.1
in which R1, R'1 and R111 are the same or different alkyl or aryl radicals and X1 andX2 are sulphur
or oxygen atoms, at least one of X1 and X, being a sulphur atom, react with sulphur halides to give
products which are very suitable as active materials for insecticidallyactive preparations.
The sulphur halide is expediently converted at elevated temperatures in the presence of an inert solvent
in such a manner that the halogen is eliminated as alkyl halide, while the sulphur is more or less
completely precipitated, depending on the conditions.
In the case of the use of disulphur dichloride, the mol ratio of ester to sulphur halide advantageously
lies at 2: 1, having regard to the yield and the insecticidal effectiveness of the reaction product; in the
case of sulphur dichloride, the ratio is1:1 to 2: 1.
The addition of copper powder or of a copper compound as catalyst results in an easier splitting off of
the alkyl halide and of the sulphur. The reaction which takes place is exemplified by the following
equation: 2RCl + 2 S+ [(RO)2.POS]2 ably contains the correspondingdisulphides.
The following Examples are given for the purpose of illustrating the present invention:
EXAMPLE 1.
156 g. (1.0 mol) trimethyl thionophosphate in 400 ml. chlorobenzene are mixed with 70 g. (0.5
mol)sulphur dichloride. After the addition of 0.5 g. copper powder, the reaction mixture is heated, with
stirring, for one hour at800C. and the temperature then increased in the course of Z hours to11(120 C.
45g. (0.9 mol) methyl chloride condense in a connected cold-trap.
Thechiorobenrene solution is distilled at 1000C./12 mm. Hg. down to a residue. After filtering off 31
g. (1 mol) sulphur with suction, there is obtained 132 g. of a red-brown product which is only slightly
soluble in water. By distillation in a high vacuum, there can be isolated about20i% of volatile
components which mainly consist of trimethyl thiophosphate.
Increasing the proportion of disulphur dichloride brings about an increasing formation of resinous
products which are difficultly soluble in common organic solvents. A redudon of the reaction
temperature to600C. leads to a reduction in the amount of methyl chloride formed and the formation of
less effective insecticidal compounds.
EXAMPLE 2.
When carrying- out the reaction described in
Example 1 but without the addition of the copper powder, there are obtained 0.9 mol methyl chloride
but only 0.3 mol sulphur.
There remains behind 135 g. of a brown residue which differs from that of Example 1 by a lower
insecticidal activity.
EXAMPLE 3.
129/612
A solution of 156 g. (1.0 mol) trimethyl thionophosphate in 400 ml. chlorobenzene is mixeddropwise
with 102 g. (1.0 mol) sulphur dichloride, whereby the temperature increases to 550C. After subsidence
of the reaction, the reaction mixture is slowly heated to800 C.
and, after one hour, heatedfrrther to110 1200C. This temperature is maintained for two hours. About
0.75 mol methyl chloride are collected, as well as 0.16 mol hydrogen chloride, which indicates
chlorination reactions.
After distilling the residue at 1000C./12 mm. Hg. and separating off 15 g. sulphur, there are obtained
120 g. of a dark red-brown product.
EXAMPLE 4.
From 78 g. (0.5 mol) trimethyl thiolphosphate in 200 ml.chloroberizene and 35 g.
(0,25 mol)sulphur dichloride, there are obtained, when working as in Example 1, 47 g.
of a dark brown product, as well as 20 g.
methyl chloride (0.4 mol).
EXAMPLE 5.
Analogously to Example 1, from 96 g. (0.4 mol) tri-n-propyl thionophosphate and 27 g.
(0.2 mol) disulphur dichloride, there areob- tained 60 g. of a brown oil. There are also formed 13 g.
sulphur and 31 g. (0.4 mol) npropyl chloride.
EXAMPLE 6.
Using the method described in Example 1, from 100 g. (0.4 mol)O-p-chlorophenyl-O,O dimethyl
thionophosphate and 27 g. (0.2 mol) disulphur dichloride, in the presence of copper powder, there are
obtained 80 g. of a dark residue. There are also obtained 10 g. sulphur and 16 g. (0.32 mol) methyl
chloride.
EXAMPLE 7.
The testing of the compounds for insecticidal effectiveness was carried out on house flies (Musca
domestica) and corn beetles(Sito; philus granarius) in acetone solution and on rice beetle larvae
(Tribolium confusum) in wheat meal. In the case of testing against house flies and corn beetles, a
solution of the active material in acetone was applied to filter papers and, after evaporation of the
acetone, the pests werecontacted with the filter papers. In the case of the rice beetle larvae, the active
material was mixed with wheat meal and the larvae placed thereon. The evaluation on corn beetles.
was carried out after 18 hours and on rice beetle larvae after 2 (a) and 10O days, respectively. The
results obtained are set out in the following Table:

Method ofCombating Fungi
We,FARBENFABRIKEN BAYER AKTIEN
GESELLSCHAFT, a body corporate orgamsed under the laws of Germany, of Leverkusen,
Germany, do hereby declare the invention, for which we pray that a patent may be granted to us and the
method by which it is to be performed, to be particularly described in and by the followingstatement:
The present invention is concerned with new methods of combatting fungi.
According to the present invention there is provided a method of combatting fungi or of preventing
fungal growth, in which there is applied to a fungus habitat a composition containing at least one ester
of the generalformula:
EMI1.1
133/612
wherein R and R', which may be the same or different, are alkyl or alkoxy radicals containing 1 to 6
carbon atoms;
X is a cyano or thiocyano radical, or an alkylmercapto or alkylcarbonyl radical containing 1 to 4
carbon atoms;
Y is one or two hydrogen or halogen atoms or an alkyl or alkoxy radical containing 1 to 4 carbon
atoms;
A and B, which may be the same or different, are oxygen or sulphur;
and n has the value zero or one,
in admixture with a solid diluent or carrier, or in admixture with an organic solvent and an emulsifying
agent capable of producing a stable emulsion when diluted with water, or in admixture with water
containing an auxiliary solvent and/or an emulsifying agent.
R and R' preferably stand for the same or different alkyl or alkoxy radicals containing 1 to 4 carbon
atoms, such as methyl, ethyl, n- and isopropyl, sec.- and tert.-butyl radicals, whereby these radicals,
according to the above definition, can also be attached to the phosphorus atom via oxygen; X signifies,
besides the cyano or thiocyano group, in particular a methylmercapto or acetyl radical, while Y
preferably represents a hydrogen or chlorine atom or a methyl or methoxy radical.
We have found that compounds of the above-given general formula exhibit a strong fungitoxic action
and a broad spectrum of activity. Because of their low toxicity towards warm-blooded animals, they are
outstandingly suitable for combatting undesired fungal growth and good compatibility for higher plants
permits their use as plant protection agents against fungus diseases.
The esters to be used in the method according to the present invention have proved to be especially
useful in combatting rice diseases.
They show an excellent protective and, in some cases, also curative action against
Piricularia oryzae on rice.
Furthermore, the method of the invention is very effective against various fungi causing diseases on
rice and other cultivated plants.
The active esters possess an especial action against the following types of fungi:Cochiobodus
miyabeanus, Species of Mycosphaerella, Corticium, Cerospora, Alternaria andBotrytis.
The esters to be used in the method according to the present invention also have a fungitoxic effect
against fungi which attack the plants from the soil and, in part, cause tracheomycoses, such asFusarium
cub en se,
Fusarim dianthi,Verticillium alboairum and
Phialophoracinerescens,
Esters of the generalformula:
EMI2.1
(II) and esters of the generalformula:
EMI2.2
have proved to be especially fungitoxic.
In the last-mentioned formulae, the symbols
R and R' have the same meanings as above,
Z stands for a cyano or thiocyano group and
Z1 for a hydrogen atom or one or two
chlorine atoms.
Some of the active compounds to be used in the method according to the present invention have
already been described in the !iterature; they can be produced in known manner, for example, by the
reaction of appropriatedialkylphosphoric, -- thionophosphoric, phosphonic, thionophosphonic,
phosphinic, or thionophosphinic acid halides with the appropriately substituted phenols or by the
reaction of dialkyl phosphites, thiolphosphites, phosphonites, thiolphosphonites, phosphinites or
thiophosphinites with aromatic thiocyanates according to the method of United
Kingdom Patent Specification No. 992,159.
134/612
They can also be obtained fromdiallyl thiolor -thionothiolphosphoricthiol or -thionothiolphosphonic or
-thiol or -thionothiolphosphonic acid salts and the appropriately nuclear-substituted benzyl halides.
When the fungitoxic agents are used in the method according to the present invention, they can be
used individually or in combination with one another. They can also be mixed with other plant
protective agents, such as fungicides, herbicides, insecticides and bactericides.
The esters to be used in the method according to the present invention are employed in the form of the
usual compositions such as emulsifiable concentrates, spray powders, pastes, soluble powders, dusting
agents and granulates. These are produced in known manner, for example, by extending the active
materials with solvents and/or carriers, possibly with the simultaneous use of emulsifying and/or
dispersing agents (cf. Agricultural
Chemicals, March, 1960, pages35-38).
Adjuvants for this purpose are mainly: solvents, such as optionally chlorinated aromatic hydrocarbons
(e.g. xylene, benzene and chlorobenzenes), paraffins, (e.g. mineral oil fractions), alcohols (e.g.
methanol, ethanol and butanol), amines (e.g. ethanolamine), dimethyl formamide and water; solid
carrier materials, for example, natural and synthetic mineral powders (kaolins, alumina, chalk, talc,
highlydispersed silicic acid and silicates); emulsifiers, such as nonionic and anionic emulsifiers (e.g.
polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, alkyl sulphonates and aryl
sulphonates); and dispersing agents, such as lignin, sulphite waste liquors and methyl cellulose.
As mentioned above, the active compounds to be used in the method according to the present
invention can be present in the aforesaid compositions in admixture with known active substances.
In general, compositions contain between 0.1 and 95 percent by weight of active ester, preferably 0.5
to90%.
The compositions for use in the method according to the present invention are used in the usual
manner, for example, by spraying, dusting, atomising or vapourising. The active esters can be used,
depending upon the purpose, in a concentration of 5 to0.0005%.
In individual cases, it is, however, possible or even necessary to go below or to exceed this range of
concentration.
The following Examples are given for the purpose of illustrating the present invention:
EXAMPLES
A. Piricularia Test
A liquid preparation of active compoundcontaining:
1 part by weight acetone (solvent)
0.05 part by weight sodium oleate (dis
persing agent)
0.2 part by weight gelatine and
98.75 parts by weight water is prepared as follows:
The amount of active compound required for the desired concentration in the spray liquor is mixed
with the stated amount of solvent and the concentrate obtained diluted with the stated amount of water
containing the other additives and the dispersing agent.
Thirty rice plants, which are about 14 days old, are sprayed with the spray liquor until dripping wet
The plants remain in a greenhouse at a temperature of 22 to 240C. and at a relative atmospheric
humidity of about 70%, until dry. They are then inoculated with an aqueous suspension of 100,000 to
200,000 spores/ ml. of Piriculariaoryzae and placed in a chamber at 24 to 260C. and at a relative
atmospheric humidity of 100%.
Five days after inoculation, the degree of infestation of all the leaves of the treated plants which were
present at the time of inoculation is determined as a percentage of the untreated but also inoculated
control plants. 0% means that no infestation occurred and 100% that the infestation is exactly the same
as that of the control plants.
135/612
The test results obtained can be seen from the Table 1.
B. Piricularia Test
A solid preparation of the active compoundcontaining:
10 parts by weight acetone (solvent) and 100 parts by weight dust base consisting
of
95.5% calcium carbonate
4.0% silicic acid
0.5% magnesium stearate is prepared as follows:
The amount of active compound required for the desired concentration of the active compound in the
dusting agent is mixed with the stated amount of solvent, and the concentrate obtained is triturated in a
mortar with the stated amount of dust base until the solvent has evaporated.
Thirty rice plants which are about 14 days old are dusted with this agent. They are then inoculated
with an aqueous suspension of 100,000 to 200,000 spores/ml. ofPiriculana oryzae and placed in a
chamber at a temperature of24-260C. and at a relative atmospheric humidity of 100%.
Five days after inoculation, the infestation of all the leaves of the treated plants, which were present at
the time of inoculation, are determined as a percentage of the untreated but also inoculated control
plants. 0% means that no infestation occurred and 100% means that the infestation is exactly the same
as that of the control plants.
The test results obtained can be seen from
Table 1.
C.Piricularia Test
Examination of the curative effect:
In the test with the liquid as well as with the solid preparation of the active compound, the curative
effect of the compounds to be used according to the invention is determined, in addition to the
protective effect. To determine the protective effect, the method is exactly the same as that described
for the other test. For determining the curative effect, the test is only modified in that the active
compounds are here applied not before, but 24 hours after, inoculation. Compounds which
are effective according to this method of carrying out the test are capable of destroying the fungus
after infection and thus have a curative effect.

EXAMPLE
Mycelium growth test
The following nutrient medium is used:
20 parts by weight powdered agar-agar
30 parts by weight malt extract
950 parts by weight distilled water
Ratio of solvent to nutrient medium:
parts by weight acetone
100 parts by weight agar nutrient medium
The amount of active compound required for the desired concentration of the active compound in the
nutrient medium is mixed with the stated amount of the solvent. The concentrate obtained is thoroughly
mixed in the stated ratio with the liquid nutrient medium which has a temperature of about420 C., and
137/612
then poured into Petri dishes of 9 cm. diameter. Control dishes without the active compound are also
provided.
When the nutrient medium has cooled and solidified, the dishes are inoculated with the fungi specified
in Table 2, and incubated at about 210C.
Evaluation is carried out after4-10 days, dependent upon the rate of growth of the fungi. For
evaluation, the radial mycelium growth on the treated nutrient media is compared with the growth on
the control medium.
The evaluation of the mycelium growth is made as follows:
0 no mycelium growth
1 very strong inibition of growth
2 medium inhibition of growth
3 slight inhibition of growth
4 growth equal to that of untreated control
The active compounds, their concentrations and the results obtained can be seen from the following

COMPLETE SPECIFICATION
Dithiolphosphoric Acid Triesters
We,FARBENFABRIKEN BAYER AKTIEN
GESELLSCHAFT, a body corporate organised under the laws of Germany, of Leverkusen,
Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and
the method by which it is to be performed, to be particularly described in and by the
followingstatement:
The present invention relates to certain new dithiolphosphoric acid triesters, to a process for their
production and to their use as fungicides.
These new compounds have the general formula
EMI1.1
in which
R is a alkyl radical with 1 to 6 carbon atoms, R' is a halogen atom, a nitro group or an alkyl or alkoxy
radical with 1 to 4 carbonatoms, m is O, 1, 2 or 3and n is O, 1, 2 or 3.
From French Patent Specification No.
140/612
1,378,035 there are already known (thiono)dithiolphosphoric acid diester monoamides of the general
formula
EMI1.2
in which
R, and Rb may be hydrogen atoms, alkyl or aryl radicals,
Re or Rd may be among other things, aryl radicals, and
X is an oxygen or sulphur atom.
According to the particulars given in this
French patent specification, these compounds are suitable for the control of plant pests and plant
diseases.
The present invention also provides a process for the production of an S,S-diphenyldithiolphosphoric
acid triester of the general formula (1) which enables it to be obtained smoothly, with good yields and
in outstanding purity. In this process a phosphoric acid monoester dihalide of the formula
EMI1.3
is reacted with a thiophenol of the general formula
EMI1.4
in the form of a salt or in the presence of an acid-binding agent.
It has been found that the S,S-diphenyldithiolphosphoric acid triesters of the invention are
distinguished by outstanding fungitoxic properties and, most surprisingly, are in this respect clearly
superior to the compounds (of analogous constitution and the same direction of activity) which are
known from the abovementioned French patent specification. They therefore represent a genuine
enrichment of the art.
The course of the process of the invention is illustrated by the following reaction equation:
EMI2.1
In formulae (3) to (5) the symbols R,
R', m and n have the meaning stated earlier above, while Hal is a halogen atom.
R is preferably a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl or n
amyl radical; R' is preferably chlorine; bromine, fluorine, a nitro, a methyl or a methoxy radical. Hal is
preferably chlorine, m
is preferably 0, 1 or 2, and n is preferablyo or 1.
As examples of the phosphoric acid monoester dihalides of formula (3) there may be mentioned
cyclohexyl-, mono-, di- and trimethylcyclohexyl-phosphoric acid monoesterdichlorides. As
thiophenols of the formula (4) there may be mentioned for example: thiophenol, 2-, 3- and 4-chloro-, 4isopropyl-, 4methoxy and 4-nitro-thiophenol, 2-, 3- and 4thiocresol, and 2-bromothiocresol.
The phosphoric acid monoester dihalides to be used in the process of the present invention as starting
materials have already been described in the literature. They can be prepared according to known
methods from the phosphorus oxyhalides by reaction with the appropriate alcohols, frequently without
need for the concurrent use of acid acceptors. The crude products obtainable in this manner can in most
cases be immediately further reacted according to the present invention without previous purification
by distillation.
The reaction of the invention is carried out preferably in the presence of an inert solvent and this term
includes a diluent. Practically all inert organic solvents are suitable. Particularly good results, however,
have been obtained with aliphatic and aromatic hydrocarbons (which may be chlorinated), such as
methylene chloride, di-, tri- andtctra-chloroethylene, chloroform, carbon tetrachloride, benzine,
benzene, chlorobenzene, toluene and xylene; ethers, for example diethyl and di-n-butyl ether, dioxan,
tetrahydrofuran; aliphatic ketones and nitriles of low molecular weight, for example acetone,
methylethyl ketone, methylisopropyl ketone and methylisobutyl ketone, acetonitrile and propionitrile;
and lowboiling aliphatic alcohols, for example methanol, ethanol and isopropanol.
141/612
As already mentioned above, the reaction may be carried out in the presence of an acidbinding agent.
For this purpose all customary acid acceptors can be used, such as alkali metal hydroxides, carbonates
and alcoholates, and also tertiary organic bases, for example triethylamine, dimethylaniline,
benzyldimethylamine and pyridine. Instead of working in the presence of an acid-binding agent, it is
equally possible first to prepare a salt, preferably an alkali metal salt or an ammonium salt, of the
thiophenol concerned and then to react the salt with the appropriate phosphoric acid monoester
dihalide.
The process of the invention can be carried out successfully within a fairly wide temperature range. In
general, the work is carried out at from- 200C to the boiling point of the mixture, preferably at O to
1000C.
The reaction is preferably carried out under atmospheric pressure, but it is also possible to work at
superatmospheric or subatmospheric pressure.
When carrying out the process according to the invention, there are used, in general, two moles of the
thiophenol per mole of the phosphoric acid monoester dihalide concerned; but the former can also be
used in excess.
The phosphoric acid monoester dihalide is expediently added dropwise (generally at the temperatures
stated above) with stirring, to a solution (this term includes a suspension) of the thiophenol concerned
(or of the appropriate thiophenolate). An external cooling of the mixture is often necessary, because the
reaction is in most cases more or less strongly exothermic. Finally, it has proved expedient to continue
stirring of the reaction mixture (after combining the starting materials) for a longer period (1 to 5 hours
or overnightoptionally with heating) in order to compIete the reaction. The products of the process are
in this case obtained with particularly good yields as well as in outstanding purity.
The working up of the reaction mixture may take place according to methods known in principle by
pouring out the mixture into water, washing and drying the organic phase, distilling off the solvent andas far as is possible-fractional distillation of the residue under reduced pressure.
The dithiolphosphoric acid triesters obtainable by the process are either obtained in the form of
crystalline compounds with sharp melting paints, which can readily be further purified by
recrystallisation from the usual solvents, or they are colourless to yellow oils, some of which can be
distilled under greatly reduced pressure without decomposition. If this is not possible, the compounds
can be purified by slight distillation, that is, they can be freed from the last volatile impurities by longer
heating under reduced pressure at slightly to moderately elevated temperatures.
Examples of the compounds which can be obtained includeO-cyclohexyl-S,S -diphenyl-, -S,S-bis-(2or 4-methylphenyl)-,-S,S-bis- (4chlorophenyl)-, -S,S-bis-(2,4- or 3,4-dichloro-phenyl)-, -S,S-bis(2,4,5- or 3,4,5- or2,4,6-trichlorophenyl)-, -S,S-bis-(2- or 3- or 4-methoxyphenyl)-, -S,S-bis-(2- or 3or 4nitrophenyl)-dithiolphosphoric acid esters as well as the corresponding 0-(2- or 3- or
4methylcyclohexyl-) and0-(1,1-,1,2-,1,3- and 1,4-dimethylcyclohexyl) derivatives, as well as the
corresponding O-trimethylcylclohexyl
S,S,-diphenyl-dithiolphosphoric acid esters.
As already mentioned, the compounds of the invention have a strong fungitoxic effectiveness against a
series of fungal pathogenic agents. By reason of this fact as well as in view of their low toxicity to
warm-blooded animals they are particularly suitable for the control of undesired growth of fungi, the
good compatibility with higher plants favouringpar- ticularly their use against fungal diseases. The
compounds can be used as fungitoxic agents in plant protection against fungi of the most widely
different classes, for example Archimycetes, Phycomycetes Ascomycetes, Basidiomycetes and Fungi
Imperfecti.
The compounds have, however, given particularly good results in the control of rice diseases, since
they possess an excellent protective and curative activity against Piricularia oryzae in rice. In addition,
they can also be used for the control of further fungal pathogenic agents in rice and other cultivated
plants.
142/612
They possess a particular activity against the following species of fungi:
Cochliobolusmiyabeanus species
Mycosphaerella species
Cerospora species
Alternaria species
Corticum species
Botrytis species.
Furthermore, these active compounds show a very good activity against fungi which attack the plant
from the soil and some of which cause Tracheomycoses, such as
Fusarium cubense,
Fusarium dianthi,
Verticillium alboatrum and
Phialophora cinerescens.
When used as fungitoxic agent, the active compounds of the invention can be used either individually
or in combination with one another. Moreover, mixture with other plant protection agents, such as
other fungicides, herbicides, insecticides and bactericides is also possible.
The active compounds according to the present invention can be converted into the usual formulations,
such as solutions, emulsions, suspensions, powders, pastes and granulates. These may be produced in
known manner, for example by mixing the active compounds with extenders, that is, liquid or solid
diluents or carriers, optionally with the use of surface-active agents, that is, emulsifying agents and/or
dispersing agents. In the case of the use of water as an extender, organic solvents can, for example, also
be used as auxiliary solvents.
As liquid diluents or carriers, there are preferably used aromatic hydrocarbons, such as xylenes or
benzene, chlorinated aromatic hydrocarbons, such as chlorobenzenes, parffins, such as mineral oil
fractions, alcohols, such as methanol or butanol, or strongly polar solvents, such as dimethyl
formamide or dimethyl sulphoxide, as well as water.
As solid diluents or carriers, there are preferably used ground natural minerals, such as kaolins, clays,
talc or chalk, or ground synthetic minerals, such as highly-dispersed silicic acid or silicates.
Preferred examples of emulsifying agents include non-ionic and anionic emulsifiers, such as
polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylarylpolyglycol ethers, alkyl sulphonates and aryl sulphonates; and preferred examples of dispersing
agents include lignin, sulphite waste liquors and methyl cellulose.
As already mentioned, the active compounds according to the invention may be present in the
aforesaid formulations in admixture with known active substances.
The formulations contain, in general, from 0.1 to 95, preferably from 0.5 to 90, per cent by weight of
active compound.
Application of the active compounds or their preparations as fungitoxic agents may be made in the
usual manner, for example by squirting, scattering, spraying or atomising. The active compound is
generally applied in a concentration of 0.0005 to 5% O/o by weight, depending on the purpose
intended. This concentration range may, however, be exceeded or gone below in special cases.
The compounds of the invention can, for example, be used successfully in the so-called ultra low
volume method, in which formulations consisting almost entirely or entirely of the active ingredient are
used.
The invention also provides a fungitoxic composition containing as active ingredient a compound of
formula (I) in admixture with a solid diluent or carrier or in admixture with a liquid diluent or carrier
containing a surfaceactive agent.
143/612
The invention also provides a method of combating fungus pests which comprises applying to the
fungus or a habitat thereof a compound of formula (I) alone or in the form of a composition containing
as active ingredient a compound of formula (I) in admixture with a solid or liquid diluent or carrier.
The outstanding fungitoxic activity of the
S,S - diphenylthiolphosphoric acid triesters which can be prepared according to the invention, as well
as their clear superiority in com parison with analogously structured products of the prior art, can be
seen from the following
Example A.
EXAMPLE A
Piricularia test: liquid preparation of active
compound
Solvent: 1 part by weight of acetone
Dispersing agent: 0.05 part by weight of
sodium oleate
Other additives: 0.2 part by weight of gelatin
Water: 98.75 part by weight ofH2O
The amount of active compound required for the desired concentration in the spray liquor is mixed
with the stated amount of solvent, and the concentrate is diluted with the stated amount of water
containing the stated additives.
30 rice plants about 14 days old are sprayed with the spray liquor until dripping wet. The plants remain
in a greenhouse at temperatures of 22 to24 C and a relative atmospheric humidity of about70-/ until
they are dry.
They are then inoculated with an aqueous suspension of 100,000 to 200,000 spores/ml of
Piricularia oryzae and placed in a chamber at24-260C and 100% relative atmospheric humidity.
5 days after inoculation, the infestation of all the leaves present at the time of inoculation is determined
as a percentage of the untreated but also inoculated control plants. 0% means no infestation; 100%
means that the infestation is exactly as great in the case of the control plants. This test indicates the
protective effect.
The active compounds, the concentration of the active compounds and the results can be seen from
Table A.
Test forcurative action
The above test is repeated, except that the active compounds are applied not before, but only 16 hours
after, inoculation. Substances which show an activity when the test is conducted in this manner are in a
position to kill the fungus after infection and thereby to execise a curative action.
The results can be seen from Table A.

The process of the invention is illustrated by the following Examples1-6.
EXAMPLE 1
EMI5.1
0.5 molar mixture:
110 g of thiophenol are dissolved in 500 ml of acetonitrile. To this solution are added 150 g of dried
potassium carbonate; 109 g of O-cyclohexylphosphoric acid ester dichloride are then added dropwise,
with stirring. The mixture is then stirred for several hours, and 200 ml of benzene are then added.
The reaction mixture is then diluted with 300 ml of water, the benzene layer is separated and dried over
sodium sulphate. After the benzene has been distilled off, 105 g (57% of the theory) of O-cyclohexylS,S-diphenyldithiolphosphoric acid ester are obtained. The compound crystallises from ligroin in
colourless needles of m.p.650C.
EXAMPLE 2
EMI5.2
0.5 molar mixture:
To a solution of 144 g of 4-chlorothiophenol in 600 ml of benzene there are added 102 g of
triethylamine; 108 g of O-cyclohexyl-phosphoric acid esterchloride are then added dropwise to the
reaction mixture at 10 to 150C, with stirring. The mixture is stirred for a further 4 hours at room
temperature and poured into 400 ml of ice water. The mixture is vigorously shaken, the aqueous phase
is separated and, finally, the organic layer is dried over sodium sulphate. After the solvent has been
distilled off under reduced pressure, there remains behind an oil which, when mixed with 150 ml of
cold petroleum ether, solidifies in crystalline form. 167 g (77% of the theory) of O-cyclohexyl-S,Sbis(4-chloro-phenyl)-dithiolphosphoric acid ester are obtained in the form of colourless crystal needles

COMPLETE SrPECIFnOATION
Organothio Phosphates and their use as Plant
Growth-Promoters
We, NIPPON KAYAKU KABUSHIKIKAISH.R, of 6,1-chome, Marunouchi, Chiyoda-ku,
Tokyo, Japan, a Japanese company, do hereby declare the invention for which we pray that a patent
may be granted to us, and the method by which it is to be performed, to be particularly described in and
by the followingstatement:
The present invention relates to new plantgrowth-promoting compositions and to a method for
promoting the growth of plants, and more especially the growth and yields of such important crops as
cereals, potatoes, and sweet potatoes. It further relates to certain new plant-growth-promoting
organothiophosphates.
Organophosphates of various types have been proposed for use as pesticides, and more especially as
aphicides or acaricides in agriculture and horticulture.
We have now found that certain known and other novel organothiophosphates possess excellent plantgrowth-promoting properties.
The invention, therefore, provides, in a first aspect, new compositions and a novel method for
prompting the growth of plants, and especially of the above-named and other important cultivated
148/612
plants. The active ingredients contained in these compositions or applied' to the seeds or tubers of the
plants in a growth-promoting amount are compounds of the general formula
EMI1.1
(I) in which
R1 represents a lower alkyl group,
R represents a lower alkoxy group or a lower monoalkylamino or dialkylamino group,
R, represents a fluorine, chlorine or bromine atom, hydrogen or methyl, and
R in a first preferred class of novel compounds, represents lower alkoxy, allyloxy, lower alkoxy-ethyl,
lower alkylthio, allylthio, lower alkoxyethylthio, lower alkoxyethyloxy or a radical
EMI1.2
wherein X represents oxygen or sulfur,
Y represents hydrogen, fluorine, chlorine or bromine,lower alkyl, lower alkoxy, lower alkyl thio,
thiocyano or isothiocyano, and
n is a number ranging from 1 to 5, but preferably 1;
or R, in another class of plant-growth-promoting compounds falling under the above formula,
represents halogen or the radical
EMI1.3
whereinRX represents hydrogen or lower alkyl, and
R, represents hydrogen, lower alkyl, allyl, or a group
EMI1.4
wherein Y and n have the same meanings as above.
Depending on the method of application used, the organothiophosphates of the above fonnula are
applied to the seeds, tubers or plant parts to be treated in concentrations of from 0.001 to 50 parts per
million, calculated on the weight of the plant material to be treated.
The term" lower" where used in this specification and in the appended claims in connection with an
aliphatic radical means that such radical has preferably not more than 5 carbon atoms.
In another aspect, the invention provides novel organothiophosphates of Formula I which pertain to
the first class of compounds falling thereunder and defined thereinbefore.
In a third aspect, the invention provides compositions for use in agriculture and horticulture which
comprise a plant-growth-promoting amount of a novel compound as defined in the said first class of
organothiophosphates falling under Formula I, in mixture with agriculturally acceptable, nonphytotoxic carriers.
In the above-described novel method, especially where carried out by dressing or soaking the seeds or
tubers of plants such as cereals, potatoes, sweet potatoes and other important crops, the
organothiophosphates of Formula I promote the elongation and the general growth of the plant body,
and increases the yields of the crops very considerably.
For example, when healthy seeds of rice are treated with the compounds of Formula I, and especially
with those of the above-mentioned preferred class thereof, the rate of elongation of the stems and roots
of the young plants is enhanced and the number of shoots is increased.
The effect of the treatment with the compounds of Formula I is long-lasting.
Moreover, we have found that the formation of shoots from unproductive stems is inhibited and the
ripening of the grains is accelerated.
The following representative compounds are named to illustrate the invention further.
Compounds pertaining to the first, preferred class:
EMI2.1
EMI2.2
149/612
EMI3.1
The following compounds pertain to the second class of compounds described hereinbefore:
EMI3.2
The following non-limitative examples illustrate the production of the compounds of
Formula I.
Temperatures are given therein by degrees
Centigrade. Percentages are given by weight.
EXAMPLE 1
11.8 g of sodium p-methoxyphenolate are added in small batches within 10 minutes to a solution of 24
g of 3 - chloro - 4 - ethoxycarbonyloxy - benzene - 1 - sulfonylchloride in 250 ml of anhydrous
benzene, with stirring at 200. The mixture is then heated to5060 and stirred for 5 to 6 more hours at
this temperature. The mixture is then filtered, the filtrate is evaporated to dryness und'er vacuo and the
residue re-dissolved in 130 ml of diethyl ether. The ether solution is filtered, the filtrate concentrated
by evaporation of the ether in vacuo and 29.7 g of 4'-methoxyphenyl3 - chioro - 4 - ethoxycarbonyloxy
- benzenesulfonate are obtained in the form of a lightyellow oil.
26.4 g of the crude ester are then dissolved in 120 ml of ethanol. 56 ml of an ethanolic 10% potassium
hydroxide solution are added dropwise to theethanolic solution at200 -with stirring, and the mixture is
then heated for 45 minutes at about 300.
The solvent is then evaporated under reduced pressure and the residue is partitioned between 250 ml
aqueous normal hydrochloric acid and 250 ml of diethyl ether. The ether solution is dried over
anhydrous sodium sulfate and evaporated to dryness. The resulting crude product is digested in 60 ml
of benzene and passed through a column charged with 50 mg of aluminium oxide (Act. I), whereupon
the column is eluted with 450 ml of benzene.
The eluate is recrystallized from benzene/ petroleum ether. 15.3 g of 4'-methoxyphenyl 3 - chloro - 4 hydroxybenzenesulfonate having a melting point ofS3--880 are thus obtained. Recrystallizationfrcm
the same solvent mixture raises the melting point to8890 .
The above-obtainedmethoxyphenyl chlorohydroxybenzene sulfonate is esterified with
O,O-dimethyl phosphoro-chloridethioate by employing the procedure described by Wagner et al in
J.med.chem. 8 p. 377 et sq. (1965) at p. 381, and there is obtained' the compound of the formula
EMI3.3
EXAMPLE 2
7 g of crude 4-hydroxy-benzene sulfinic acid and 6.35 g of4-chiorothiophenol are dissolved in 75 ml
of diethyl ether, the solution is cooledto - 50 and a solution of 6.1 g of ethyl nitrite in 20 ml of diethyl
ether is added thereto in small batches. The dark violet brown colored solution is stirred for 90 minutes
at0 and then further for 3 hours at 200 until it has become colorless. The solvent is then removed by
evaporation in vacuo and the residue is chromato graphed through a column containing 6 times its
amount of aluminium oxide (Act. I). The column is first eluted with benzene to remove4,4'-dichlorodiphenyl-disulfide which is obtained as a hypodust, and then with ethyl acetate which contains the
desired product.
The latter is recrystallized from benzene/ petroleum ether and pure 4'-chlorophenyl4-hvdroxy-benzene
thiosulfonate is obtained which has a melting point of124125o.
The latter product is then esterified withO,O-diethyl phosphoro-chloridethioate employing the
procedure described by Wagner et al, supra. The compound of Formula No. 9, supra, is thereby
obtained.
4-hydroxy-benzene-suifinic acid used as starting material in the above example is produced as follows:
53 g of 4-ethoxycarbonyloxy-benzene-sufonyichioride dissolved in 100 ml of acetone are added
dropwise within 2 hours and with stirringte a solution of 61.6 g of sodium sulfite in 500 ml of water at
150/612
200. At the same time, 37 g of sodium hydrogen carbonate are added to the solution. Stirring is then
continued for 12 hours, the solution is then clarified by filtration through Hyflo (Registered Trade
Mark) andsectioning off the acetone in a water jet vacuum. The solution is then cooled to0 and 100
ml of aqueous hydrochloric add (50 . HCI content) is added thereto. 4-ethoxcarbonyloxy-benzenesulfinic acid is obtained which is separated by suction filtration and dried for 3 hours in vacuo over
phosphorus pentoxide (M.P.7378o).
10 ml of 2-normal sodium hydroxide solution are poured onto 15 g of the crude
ethoxycarbonyloxybenzenesulfinic acid, the clear solution of about 400 resulting when gas
development ceases, is left to stand for 20 minutes and is then cooled to 100, acidified with 15 ml of
concentrated hydrochloric acid, and filtered.
The filtrate is extracted several times with a total of about 200 ml of diethyl ether, the ether solution is
dried over sodium sulfate and evaporated to dryness in vacuo. 4-hydroxybenzene-sulfinic acid is
obtained which melts at677(? with decomposition. The product must be used directly in the abovedescribed manner, for it decomposes rapidly when stored.
Other compounds falling under Formula I can be produced in a similar manner by the procedure given
in the two proceeding examples by using correspondingly substituted starting materials.
The compounds according to the invention are formulated for use in any desired way.
Generally such formulations will include the plant growth regulator in association with a suitable
carrier or diluent. Such carriers may be liquid or solid or in ointment form and are designed to aid the
application of the plant growth promoter either by way of dispersing at the location where it is to be
used, or to provide a concentrate formulation which can be made up by the user into a dispersible
preparation.
Liquid preparations thus comprise preparations of growth promoter in the form of solutions or
emulsionswhich can be used by themselves or which can be adapted to be made up with water or other
diluents to form sprays; in such cases the carrier is a solvent or emulsion base non-phytotoxic under the
condition of use. As suitable carriers for emulsions or solutions, the following materials are metioned:
Alkanols such as methanol, ethanol, and ethylene glycol, ketones e.g. methyl ethyl ketone or acetone,
ethers, aromatic compounds illustrated by benzene, xylene, and solvent naphtha, and liquid esters,
especially ethyl acetate.
Solid preparations comprise dusts and wettable powders, as well as semi-solid preparations such as
ointments. Such preparations may comprise inert solid and/or liquid diluents such as clays, kaolins,
bentonite, talcum, kieselguhr and starch, or ointment bases such as resins, lanolin, paraffins, Vaseline
(Registered.
TradeMark), bentonite, cellulose and its derivatives, pectins, polyethyleneglycol or polyalcohol esters
of fatty acids. These preparations usually contain a wetting, dispersion or emulsifying agent, as well as
stabilizers. Soaps, alkyl sulfonates, esters of fatty acids, hydroxyalkyl amines are mentioned as
surfactants suitable for use as emulsifier, dispersing agent or penetrating agent.
Moreover, the compounds according to the invention may be used, if desired, in admixture with
compatible fungicides, other plant growth promoters and/or fertilizers.
The following non-limiting examples are given to illustrate the above-described compositions. Parts
are given by weight unless expressly stated otherwise.
EXAMPLE I
By admixing 10 parts of 0,0 - diethyl - 0 (4 - dimethylsulfamoyl - phenyl) phosphorothioate with 60
parts of talcum and 30 parts of clay, and crushing, there is obtained dust composition usable as a seed
dressing agent.
EXAMPLE II
151/612
20 parts ofO,O - diethyl - 0 - [4 - (p chlorophenyl) - sulfamoylphenyl] phosphorothioate are admixed
with 60 parts of kaolin, 17 parts of diatomaceous earth, one part of alkylnaphthaline sulfonate, and 2
parts of lignin sulfonate to give a wettable powder which is readily dispersed and suspended in water to
be used as a soaking agent.
EXAMPLE III

of xylene and 33 parts of methyl-naphthalene, and admixing them with 17 parts of poly-alkylphenol
ethylene oxide gives a emulsion which is readily dispersed and suspended in water to be used for
soaking seeds therewith.
EXAMPLE IV 5 parts of O,N - dimethyl - O - (4 - dimethylsulfamoyl - phenyl) phosphoroamidothioate are dissolved in 15 parts of xylene, and 60 parts of starch and 20 parts of polyvinyl
pyrrolidone are admixed with them to formulate a pellet which is readily dispersible in water for
soaking seeds therewith.
EXAMPLE V 0.4 parts of O,O - diethyl - O - (2 - chloro 4 - isopropylsulfamoyl - phenyl) phosphorothioate are admixed with 25 parts of vaseline and 25 parts of stearyl alcohol, and as they are
being melted, one part of sodium laurylsulfonate, 12 parts of propylene glycol and 36.6 parts of
distilled water are added to make up an ointment which is used for coating seeds.>;/RTI;

The above table shows that compounds of
Formula I used as active ingredient in seed dressings promote the elongation of roots and stems of the
rice plants.
EXPERIMENT 2
Pot test
Healthy rice seeds were coated with 5%, 2% and 1%, respectively, of their total weight, of a dust
which contained 10% of O,O - diethyl - O - (4 - dimethylsulfamoyl - phenyl) phosphorothioate
(Compound No. 24) and, a second series of seed batches with the aforesaid amounts, respectively, of a
dust which contained10% of 0,0 - diethyl - 0- (4 phenyl thiosulfonylphenyl) phosphorothioate
(Compound No. 4).
Pots filled with gravel and pots filled with soil of a rice paddy were prepared for this test. In the case
of gravel-culture, nutrient solutions known as " balanced solution for gravel-culture " were exchanged
once a week.
Gravel-culture conditions were the same as the conditions of growing the paddy seedlings, except that
the paddy soil was moistened with tap water. Dressed seeds of rice were sown into 20 boles at the rate
of 2 grains per hole, and cultivated at 280Ct 300C in the greenhouse. 45 days after sowing, the length
of roots, height of grasses, number of shoots, fresh weight of stems and leaves, and fresh weight of
roots were measured.
The results are shown in Table II below.

COMPLETE SPECIFICATION
Thiolphosphoric (-Phosphonic) Acid Esters
We,FARBENFABR3:REN BAYER AKTIENGELSCHAFT, a body corporate organised under the
laws of Germany,uf Leverkusen, Germany, do hereby declare the invention, forwhich we pray that a
patent may be granted to us, and the method by which it is to be performed, to be particularly described
in and by the followingstatement:
The present invention relates to new fungitoxic thiolphosphoric (-phosphonic) acid esters and to their
preparation and use. These compounds have the generalformula:
EMI1.1
in which R, stands for an alkyl radical with 1 to 4 carbon atoms, andR2 stands for an alkyl radical
with 1 to 4 carbon atoms or analkoxy radical with 1-4 carbon atoms.
In U.S. Patent Specification No. 2,690,450, thiolphosphoric acid aryl esters are already described
which possess parasiticidal properties, in particular insecticidal properties, but also fungicidal
properties. From this publication, however, it emerges only that the above-mentioned compounds are
suitable as fungicides for the control of brown rot (Sclerotinia fructicola) and early blight (Alternaria
solani). However, from U.S. Patent
Specification No. 2,690,450 it cannot be learned whether the compounds disclosed there possess also
an effectiveness which would in practice be adequate against fungoid pathogenic agents on rice plants,
particularly the fungus Piricularia oryzae.
159/612
We have found that the new thiol-phosphoric (phosphonic acid esters of formula (1) are distinguished
by outstanding fungitoxic properties, particularly in regard to fungoid pathogenic agents on rice plants.
Surprisingly, they are in this respect distinctly superior to the known active compounds of analogous
constitut;on already proposed for the same purpose. The new compounds therefore represent a
substantial enrichment of the art.
We have also found that thiol-phosphoric (-phosphonic) acid esters of formula (1) are obtained
smoothly and with good yields when halomethylnaphthalenes of the formula:EMI1.2
are reacted with thiol-phosphoric (-phosphonic) acids of the general formula:
EMI1.3
in the form of the corresponding salts or in the presence of acid-binding agents.
The course of the process of the invention can be represented by the followingequation:
EMI2.1
In all the above formulae, thesymbols, R1 and R2 have the meaning stated earlier above, while Hal
stands for a halogen atom.
Preferably, R1 stands for a methyl, ethyl, n-propyl or isopropyl, n-butyl, isobutyl or sec.-butyl radical;
preferably, R2 stands for one of these radicals or a methoxy ethoxy, npropoxy, or isopropoxy, nbutoxy,isobutoxy or sec.-butoxy radical.
The halomethylnaphthalenes used in the process are known from the literature and can readily be
prepared, even on an industrial scale.
The following is a list of some of the thiolphosphoric (-phosphonic) acid salts which may be used as
starting substances: Ammonium, potassium or sodium,O,O-dimethyl, -diethyl, -diethyl, -di-isopropyl,
-di-sec.-butyl, Omethyl-O-ethyl, O-methyl andO-ethyl-O-n- and -isopropyl, O-methyl-O-n- and sec.
butyl,O-ethyl-O-n and sec.-butyl, O-isopropyl-Osec.-butyl thiolphosphate.
The process of the invention is carried out preferably in the presence of inert solvents.
Examples thereof are hydrocarbons and chlorinated hydrocarbons, such as methylene chloride,
chloroform, carbon tetrachloride, benzene, toluene, xylenes, chlorbenzenes, and also ethers, for
example diethyl or dibutyl ether, dioxan, tetrahydrofuran, and low-boiling aliphatic ketones and
nitriles, for example acetone, methylethyl ketone, methylisopropyl ketone or methylisobutyl ketone as
well as acetonitrile or proprionitrile.
As already mentioned above, the salts (preferably the alkali metal or ammonium salts) of the thiolphosphoric (-phosphonic) acids may serve as starting substances for the reaction of the invention.
In one alternative of the process, it is possible, instead of starting from the salts, to use the
corresponding free acids and to react these in the presence of acid-binding agents.
Particularly suitable acid acceptors include alkali metal carbonates or alcoholates, such as potassium or
sodium carbonate, methylate or ethylate, and also tertiary bases, such as trethylamine, dimethylaniline
orpyridiae.
The reaction temperatures can be varied within a fairly wide range. In general, the work is carried out
at 30 to80 C, preferably at 40 to 700C.
In carrying out the processaccording to the invention equimolar amounts of halomethylnaphthalene
and thiol-phosphoric (-phosphonic) acid salt (or a mixture of the free acid concerned and the acidbinding agent) are generally used.
It has proved expedient to add, with stirring at the above-mentioned temperatures, the
halomethylnaphthalene to the already prepared solution or suspension of the thiolphosphoric (-
160/612
phosphonic) acid salt in a suitable solvent and then, in order to complete the reaction, to stir the
mixture further for a longer period (for example 1 to 3 hours), optionally with heating.
The working up of the mixture may take place in a manner which is known in principle by filtration of
themixture, evaporation of the solvent, taking up of the oily, precipitated reaction product in another,
water-immiscible organic solvent, preferably one of the abovementioned chlorinated hydrocarbons,
washing of the organic layer until there is a neutral reactien, separation of the phases, drying of the
solution and again distilling off the solvent and, optionally, fractional distillation of the residue under
reduced pressure.
The thiol-phosphoric (-phosphonic) acid esters of the invention are obtained in most cases in the form
of colourless or pale yellow to brownish coloured, water-insoluble oils, some of which can be distilled
under greatly reduced pressure without decomposition and sometimes solidify in crystalline form after
standing for a long period.
As mentioned above, the products of the process are distinguished by a strong fungitoxic effectiveness
and a wide spectrum of activity.
Surprisingly, they possess, despite this outstanding activity against phytopathogenic fungi, only a
slighttoxidty in respect ofwarm- blooded animals (median toxicityLD,0 in the rat per os 100 to 1000
mg/kg animal). To this is to be added the excellent compatibility in respect of higher plants of the
compounds which can be prepared according to the invention. By reason of these properties, the
produets of the process are eminently suitable as plant protection agents against fungoid diseases.
Fungicides involving these active compounds can be used for the control of fungi of the most widely
different classes, for example
Archimycetes, Phycomycetes, Ascomycetes,Basidiomycetes, Fungi Imperfecti. However, the active
compounds have given particularly good results against fungoid diseases of rice, in particular those
caused by the fungus Piricularia oryzae. The active compounds have an excellent protective and
curative activity against this fungus.
In addition, they can also be used for the control of other fungoid pathogenic agents on rice and otber
cultivated plants. They possess a particular activity against the following species of fungi:
Cochliobolus miyabeanus species
Mycosphaerella species
Corticium species
Cerospora species
Alternaria species
Botrytis species
Moreover, the active compounds of the invention show a very good activity in respect of fungi which
attack the plant from the soil and some of which cause tracheomycoses, such as
Fusarium cubense,
Fusarium dianthi,
Verticillirnii alboatrum and
Phialophora cinerescens.
When the active compounds of the invention are used as fungitexic agents, they may be used
individually or in combination with one another. Furthermore, they may be mixed with other plant
protection agents, such as other fungicides, herbicides, insecticides or bactericides.
The active compounds of the invention may be applied as such.
The active compounds of the invention can be converted into the usual formulations, such as solutions,
emulsions, suspensions, powders, pastes or granulates. These may be produced in known manner, for
example by mixing the active compounds with extenders, that is liquid or solid diluents or carriers,
optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents.
In the case of the use of water as an extender, organic solvents can for example also be used as
auxiliary solvents.
161/612
As liquid diluents or carriers, there are preferably used aromatic hydrocarbons, such as xylenes or
benzene, chlorinated aromatic hydrocarbons, such as chlorobenzenes, parffins, such as mineral oil
fractions, alcohols, such as methanol or butanol, or strongly polar solvents, such as dimethyl
formamide or dimethylsuiphoxide, as well as water.
As solid diluents or carriers there are preferably used ground natural minerals, such as kaolins, clays,
talc or chalk, or ground synthetic minerals, such as highly-dispersed silicic acid or silicates.
Preferred examples of emulsifying agents include non-ionic and anionic emulsifiers, such as
polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylarylpolyglycol ethers, alkyl sulphonates and aryl sulphonates; and preferred examples of dispersing agents
include ligninsulphite waste liquors and methyl cellulose.
As already indicated above, the active compounds of the invention may be present with other active
substances in the above formulations.
The formulations contain, in general, from 0.1 to 95 per cent by weight of active compound, preferably
from 0.5 to90%.
The active compounds of the invention and preparations thereof may be applied in customary manner,
for example by squirting, dusting, spraying, atomising.
According to the purpose for which it is to be used, the active substance may be applied in a
concentration of 0.0005 to5% for example0.01--5':6. In special cases, however, it is possible, or even
necessary, to exceed' or to go below this range of concentrations.
The invention also provides a fungitoxic composition containing as active ingredient a thiolphosphoric (-phosphonic) acid ester of formula (I) in admixture with a solid diluent or carrier or in
admixture with a liquid diluent or carrier containing a surface-active agent.
Theinvention also provides a method of combating fungi which comprises applying to a fungus
habitat a thiol-phosphoric (-phosphonic) acid ester of formula (I) alone or in the form of a composition
containing as active ingredient a compound of formula (I) in admixture with a solid or liquid diluent or
carrier.
The outstanding fungitoxic effectiveness of the thiolphosphoric acid esters according to the process, as
well as their distinct superiority compared with known products of analogous constitution and the same
direction of activity, can be seen from the following experimental testresults: EXAMPLE A
Piricularia test: liquid preparation of active compound
Solvent: 1 part by weight acetone
Dispersing agent: 0.05 part by weight sodium oleate
Other additives: 0.2 part by weight gelatin
Water: 98.75 part by weight H2O
The amount of active compound required for the desired concentration in the spray liquor is mixed
with the stated amount of solvent, and the concentrate is diluted with the stated amount of water
containing the stated additives.
30 rice plants about 14 days old are sprayed with the spray liquor until dripping wet. The plants remain
in a greenhouse at temperatures of 22 to24"C and a relative atmospheric humidity of about70l, until
they aredrop.
They are then inoculated with an aqueous suspension of 100,000 to 200,000 spores/ml of
Piricularia oryzae and placed in a chamber at24--250C and10001,0 relative atmospheric humidity.
5 days after inoculation, the infestation of all the leaves present at the time ofinecula- tion is
determined as a percentage of the untreated but also inoculated control plants.0:6 means no
infestation;100% means that the infestation is exactly as great as in the case of the control plants.
162/612
The active compounds, the concentrations of the active compounds and the results can be seen from
the followingTable:
TEST forcurative action
In addition to the protective action determined as described above, the curative action of the active
compounds of the invention is also determined.
The test for curative action differs in certain points from the test procedure described above (which
only yields evidence in respect of the protective effect) in so far as the active compounds are applied
not before, but only after 16 hoursafter, inoculation. Substances which show an activity when the test
is conduced in this manner are in a position to kill the fungus after infection and thereby to exercise a
curative action.
The results of the test for curative action can also be seen from the following Table:

(54)METHOD OF tCOM!BATZG WEEDS
(71) We, FARBENFABRIKEN BAYERAKTIENGBSELLSCHAFT, a Body corporate organised
under the lawsolf Germany, of
Leverkusen, Germany, dohereby declare the invention, for which we pray that a patent may be granted
to us, and the method by which it is Ito be performed, to be particularlydescribed in and by
the'fcllowing statement: The present invention relates to the use as a herbicide of a certain amidothionophosphoric acid
ester.The invention provides a method of combating weeds which comprises applying to the weeds or a
habitat thereof the compound of the formula
EMI1.1
(I) alone or in admixture with a solid or liquid diluent or carrier.
A compound of U.S. Patent No. 3,074,790,o - (2,4 dEichlorophenyl) - O - methyl - Niso propylphosphoroamidothioate, possesses activity as a herbicide. It 'has now been found that O - (2 nitrophenyl) - O - ethyl - Nisoprophylphosphoroamidcthioate of the structural formula (I) has strong
herbicidal activity, especially against weeds in paddy fields, weeds of the Graminae family, broad
leaved weeds and perennial weeds. Moreover it shows selective herbicidal activity, for example in
exhibiting little or no phytotoxicity to rice.
According to British Patent No. 659,682, it is known that compounds of the type of that used in the
present invention possess insecticidal and fungicidal activities. However, that patent indicates only that
171/612
these compounds have insecticidal and acaricidal efficacy and are also effective for the control of
harmful fungi on plants and can be used as sprayingpreparations. There is no description of a test
example showing their efficacy, and no indication of anyherbicidal activity. There is also no mention
of the applicability of the compounds to soil or ay reason to expectherbiddal activity.
The present ivention is based on the discovery that O -(2 - nitrophenyl) - O - ethyl
N - iso [email protected] of formula (I) shows remarkably good selective herbicidal
efficacy when used especially as apre-emergen soil treatment herbicide in the control of weeds in
areasof crop cultivation, e.g. paddy fields.
The compound used in the present invention is obtained easily and with good yieldsby reacting 0 ethyl - N -isopropyl - amidothionophosphoric acid ester halide with 2nitrophenol, preferably in the
presence of an acid binding agent, or by reacting it with a salt of 2-nitrophenol as shown by the
following reaction scheme:
EMI1.2
(II) in which Hal is a halogen [email protected], preferably a chlorine atom, and Me'is a hydrogen atom, alkali
metal atom or ammonium radical.
Example 1 illustrates the preparation of the compound used in the present invention.
EXAMPLE 1
EMI1.3
(I)
14 g (0.1 mol)of 2-nitrophenol were dissolved in 100 ml of acetonitrile and 14 g of anhydrous
potassium carbonate were added to the solution. 20.2 g (0.1 mol) ofO - ethyl
N - iso-propylamidothionophosphoric acid ester chloride were added dropwise at 5060 C, with
vigorous stirring. The inorganic salt produced was filtered off and the filtrate was distilled to remove
the solvent. The residue was dissolved in 100 ml of benzene and the benzene solution was washed
with1% aqueous solution of sodium carbonate,which was dried over anhydrouns sodium sulphate.
After distillation off of the benzene, 25.3 g of O -(2 - nitrophenyl) - O - ethyl - N [email protected] were obtained.
The active compounds used according to the present invention can be converted into the usual
formulations, such as solutions, emulsions, suspensions, powders, pastes and granulates. These may be
produced in known manner, for example by mixing the active compounds with extenders, that is, liquid
or solid diluents or carriers, optionally with the use of surface-active agents, that is, emulsifying agents
and/or dispersing agents. In the case cf the use of water as an extender, organic solvents can, for
example, also be used as auxiliary sclvents.
As liquid diluents or carriers, there are preferably used aromatic hydrocarbons, such as xylene or
benzene, chlorinated aromatic hydrocarbons, such as chlorbenzenes, paraffins, such as mineral oil
fractions, alcohols, such as methanol or butanol, or strongly polar solvents, such asmethyl formamide
or dimethylsulphoxide, as well as water.
As solid diluents or carriers, there are preferably used ground natural minerals, such as kao!ins, clays,
talc, chalk or montmorillonite, or ground synthetic minerals, such as highly-dispersed,ilicic acid or
silicates.
Preferred examples of emulsifying agents include non-ionic and anionic emulsifiers, such
aspolyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example
alkylarylpolyglyccl ethers, alkyl sulphonates and aryl sulphonates; and preferred examples of
dispersing agents include lignin, sulphite waste liquors and methyl cellulose.
The compounds can be applied in admixture with such adjuvants generally used for agricultural
chemicals as spreaders, emulsifiers, wetting agents, adhesive agents, etc. Further, they can be applied
in admixture with other herbicides, for example phenoxy compounds, chlorophenol compounds,
carbamate compounds, diphenyl ether compounds, urea compounds or triazine compounds, and also
172/612
with plant growth regulators, insecticides, acaricides, hematocides, fungicides and other agricultural
chemicals and fertilizers. Mixed application especially with phenoxy herbicides, for example esters of
MCPA(2 - methyl - 4chlorophenoxy acetic acid), is effective and gives rise to synergistic effects.
Herbicidal compositions containing the active compound of the formula (I) are illustrated in
thefollowing Examplcs 2-6, in which parts and percentages are by weight.
EXAMPLE 2
5% or the compound or the rormula (I) and95% of a mixture of talc and clay were formu @@@

by mixing and crushing, and used by dusting as such.
EXAMPLE 3
20% of thecompound of the formula (I),75% of a mixture ofZeeklite (a mixturecf 1pin by weight of
talc and 3 parts by weight of kaolin) and clay,3% of sodium alkylbenzene sulphonic acid and2% of
sodium dinaphthyl-merhane disulphonic acid are formulated into a wettable powder by mixing and
crushing and applied diluted with water.
EXAMPLE 4
20% of the compound of the formula (I),75 /O of xylol and5% of apolyoxyethylene alkyl aryl

Kakaku Kogyo (K.K.) are formulated into an emulsifiable concentrate by mixing and stirring, and
applied diluted with water.
EXAMPLE 5
Thecompound cf theformula (I) is dissolved in xylol while heating. The solution is sprayed onto clay
granules while rotating and mixing so that about 10% of active ingredientis incorporated in the
granules. The granular formulation is used by scattering as such cn the surface of soil.
EXAMPLE 6
Three parts of the compound of rhe formula (1), 1.5 parts of ethyl ester of MCPA (2methyl - 4 chlorophenoxy acetic acid), and 95.5 parts of bentonite are mixed well. The mixture containing 10%cf
water is granulated. It is applied to the soil surface of paddy fields.
The compositions of the present invention generally contain0.1-95% by weight, preferably0.5.-90%
by weight, of active compound.
The application may be carried out byordinary methods, for example watering, spraying, atomizing,
dusting or scattering.
The most suitable application time is before the germination of the weeds to be eradicated.
When application is carried out mainly before the germination of cultivated plants, the general
conditions of cultivation arenct so important, tut the quantity per unit area of active compound to be
applied and the appli- cation method are important.
The quantities of the active compound to be used according to this invention may varywithin a fairly
wide range. They depend upon various factors, for example the conditions of cultivation, soil, weeds
and weather as well as the purpose of application. The compound of the present invention tends to
show nonselective herbicidalacticn when used in an amount of more than 500 g per 10 a. in paddy
fields or dry fields, but tends to show selective herbicidal action when used in smaller amounts.
Thus, this invention provides crops protested from damage by weeds by being grown in areas in
which, immediately prior to and/or during the time of the growing, the compound of the formula (I)
was applied alone or in admixture with à solid or liquid diluent or carrier.
The outstanding herbicidal action of thecompound of the present invention as well as its superiority as
a herbicide to the previously knowncompounds is clearly shown by thefollowing Examples A and B.

(54) PROCESS FOR COMBATING TNSTS IN ThA A RICE
CULTURES
(71) We, SANDOZ LTD., of 35 Lichtstrasse, 4000 Basle, Switzerland, a Swiss Body
Corporate, do hereby declare the invention, for which we pray that a patent may be granted to us, and
the method by which it is to be performed, to be particularly described in and by the
followingstatement:
The present invention relates to the control of destructive insects in tea and rice cultures.
It is known that the insect Ectropis bhurmitra, and the insects Chilo suppressalis, Tryporyza incertulas,
Tryporyzainnotata, Chilotiara potychrysa and Sesamia inferens cause considerable damage in tea and
rice cultures respectively. Furthermore, it is known that that group of insects known as stem borers are
a particular nuisance in rice cultivation.
According to our invention we provide a process for combating insects in a tea or rice culture which
comprises applying O.O-diethylthionophosphoric acidO- [quinoxalyl-(2)] ester of formula I,
EMI1.1
to a tea or rice culture.
TheO,O,-diethyl-thionophosphoric add 0 [quinoxalyl-(2)] ester may be present in the tea or rice
culture in a manner conventional for the application of other insecticides to such cultures. Thus for
example the compound may be applied to the culture on its own or preferably in combination with an
agriculturally acceptable diluent or carrier. Suitably the compound may be applied in the form of a
dusting or spraying agent, e.g. as a solution or dispersion in water or a suitable organic solvent, e.g.
alcohol, petroleum, tar distillates etc., and preferably in combination with an emulsifying agent, e.g. a
liquid polyglycol ether derived from a high molecular weight alcohol, mercaptan or alkylphenol and an
alkylene oxide.Suitable organic solvents, e.g. ketones, aromatic, optionally halogenated hydrocarbons,
mineral oils etc., may also be added to the mixture as solution aids.
176/612
The spraying and dusting agents may contain the usual inert carrier materials, e.g. talc, diatomaceous
earth, bentonite, pumice, cellulose derivatives and the like, and the usual adhesives and wetting agents
to improve adhesiveness and wettability.
The O,O-diethyl-thionophosphoric acid 0 [quinoxalyl-(2)] ester may be present in the formulations as
a mixture with other known active agents. Formulations suitable for use in the application of a
compound of formula I to a locus generally contain between 0.01 and 95 percent, and preferably
between 0.5 and 90% by weight of active agent.
The compound of formula I may be applied to the rice culture at a dose of from 0.25 to 1 kg and
preferably from 0.5 to 0.75 kg per hectare. For the treatment of rice the compound of formula I may
also be applied by addition to the paddy water or by soaking seedlings in a composition containing the
compound of formula I.
The compound of formula I used as active agent in the process of our invention may be made by
reacting 2-hydroxy quinoxaline, or a derivative thereof in which the hydrogen of the hydroxy group is
replaced by another cation, with anO,O-diethyl thionophosphoryl halide, with the proviso that when 2hydroxy quinoxaline is used the reaction is effected inthe presence of an acid-binding agent.
The process is preferably carried out in thepresence of a solvent or diluent at a temperature of
between 20 and 1200 and preferably
between 40 and800 C. TheO,O-diethyl thionophosphoryl halide is preferably a
chloride or bromide.
The invention is illustrated, but in no waylimited by the following Examples. Where
concentrations are expressed as percentages,these are percentages by weight
EXAMPLE 1
Activity against Ectropisbhurmitra in tea
Tea bushes were sprayed with an aqueous composition made by diluting commercially available
emulsion concentrates of the comparison compounds and concentrate comprising25% ofO,O-diethylthionophosphoric acid 0 [quinoxalyl >; 2)1 ester,25% ofisooctyiphenyl decaglycol ether and 50%

(54) FUNGICIDE FOR PLANT PROTECTION
(71) We, BADISCHE ANILIN- & SODA-FABRIK AKTIENGESELL
SCHAFT, aGerman Joint Stock Company of 6700 Ludwigshafen, Federal Republic of Germany, do
hereby declare the invention, for which we pray that a patent may be granted to us, and the method by
which it is to be performed, to be particularly described in and by the followingstatement:
The present invention relates to fungicides for protecting plants and containingS,S-diesters of Nsubstituted phosphoramidodithioic acid S,S-dialkylamidodithiophosphates, a process for producing
these compounds and their use asfungicides.
Some of these esters have been proposed for use as defoliants, desiccants, insecticides and acaricides.
We have now found that S,S-diesters of N-substituted phosphoramidodithioic acid of the formula
EMI1.1
where R1 and R2, independently of one another, each denote alkyl of 1 to 4 carbon atoms (e.g. methyl,
ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tert-butyl), or together, denote ethylene or, R3 and R4,
independently of one another, each denote alkyl of 1 to 12 carbon atoms; cycloalkyl (cyclopentyl,
cyclohexyl,cyclooctyl); cycloalkyl substituted by methyl; alkoxyalkyl; benzyl; phenyl; chloro-
181/612
substituted phenyl; phenyl substituted bycarbamoyloxy;fi-morpholinoethyl; orR3 may further denote
hydrogen, and/or R4 may denote dimethylamino, orR and R4 together with the nitrogen atom whose
substituents they are denote an unsubstituted or alkyl-substitutedmonocydic saturated (i.e. multiple
bond-free) heterocyclic radical with a 5- or 6-membered ring (e.g.morpholine, thiomorpholine,
pyrrolidine or piperidine), have a strong fungicidal action on fungus pathogens in monocotyledons,
such as cereals (e.g. barley, oats,
Indian corn, and especially rice) or bananas for instance on the fungus Piricularia oryzae.
PreferablyRs and R4 each independently denote a saturated hydrocarbon radical of not more than 12
carbon atoms optionally substituted by an alkoxy radical of 1 to 4 carbon atoms, or R4 denotes such a
radical, andR denotes hydrogen; orRa and R4 each independently denote a benzyl or phenyl radical or
a phenyl radical substituted oby 1 to 3 chlorine atoms and/or by a carbamoyloxy group, orNR3Rf
denotes an unsubstituted oralkyl-substituted piperazine group, orN (nCsH7)2.
In a useful class of compoundsRD, R2, R3 and R4 all denote hydrocarbon radicals orR3. and/orRu
may denote chlorophenyl radicals.
The compounds to be used according to the invention may readily be prepared by reacting a compound
of the formula
EMI1.2
5 10 15 20 25 30 35 whereRl and R2 have the above meanings and X denotes halogen, preferably
chlorine with an amine of the formula
EMI2.1
whereR andR' have the above meanings, preferably in the presence of a solvent, advantageously for
instance benzene or toluene, at from10 to110 C.
Without isolating theS,S-dialkylphosphorous amide, oxidation to the fungicidal
phosphoramidodithioic derivatives is then effected with an oxidant, advantageously with an aqueous
solution ofH,O,. The reaction steps are illustrated by the following scheme:
EMI2.2
The S,S-dialkylphosphorous chlorides used as starting materials are known from the literature and may
be prepared with facility (cf. Touben-Weyl, Methoden der organischen Chemie, 12/2, p 91).
The amines employed are also known and may be easily produced in substantial amounts. Generally,
the amines are used in such amounts that there are approximately two molar equivalents of the amine to
one molar equivalent of the S,S-dialkylphosphorus chloride. In the case of amines which due to their
low basicity only react sluggishly or are not easily accessible, one molar equivalent of the amine may
be replaced by triethylamine or a similar tertiary amine, e.g., pyridine, asacid-binding agent. One mole
of amine may therefore be replaced by one mole of a conventional agent which binds hydrogen
chloride.
The reaction may be carried out for instance by dripping the amine into a solution of S,Sdialkylphosphorous chloride at30 to60 C, and then stirring the reaction mixture at 10 to110 C,
preferably for example in boiling benzene at70"C, until no more amine hydrochloride separates out.
The precipitated amine hydrochloride may be suction filtered after cooling to25 C and the filtrate
oxidized, or the whole reaction mixture is reacted withH2O--.
Advantageously, oxidation in accordance with equation 2 is carried out by allowing30,b (by
weight)H,O to drip at105 to40 C into the solution ofS,S-dialkyl- phosphorous amide (with or without
amine hydrochloride) in benzene or toluene with vigorous stirring and external cooling, and
subsequently boiling for instance the benzolic solution for 1 to 4 hours under reflux to complete the
reaction.Working up is then effected by washing the organic phase, after cooling, with aqueous3% (by
weight)NaHCO solution (possibly after suction filtering the amine hydrochloride), drying overNa SOl,
and removing the solvent in vacuo atSOD to60"C by direct distillation.
The compounds are obtained in very pure form, and are mainly pale yellow to orange colored oils, or
crystalline compounds which need no further purification.
182/612
The active ingredients have a low toxcity to warmbloods and a strong fungicidal action on fungi in
monocotyledons, e.g., on Erisyphe graminis in cereals (e.g. barley and oats), Helminthosporium sp. in
barley and oats, Piricularia grisea in bananas, and
Pellicularia sasakii and Piriculariaorvzae in rice.
The plants to be protected against fungus attack are treated, e.g., sprayed or dusted, with the active
ingredient. It is also possible to treat the seed or seedlings with the active ingredient before sowing or
planting. The active ingredients are used in fungicidal amounts.
The preparation of the active ingredients is illustrated by the following example.
EXAMPLE 1
Preparation ofS,S-diisopropyl N-isopropylphosphoramidodithioatephosphate
21.7 parts by weight of S,S-diisopropylphosphorous chloride is dissolved in 100 parts by weight of
benzene. While stirring, a solution of 11.6 parts by weight of isopropylamine in 50 parts by weight of
benzene is dripped in, and the mixture is then boiled under reflux for 2 hours. After cooling, the
hydrochloride which has separated out is suction filtered. Slowly and with ice cooling, 11.5 parts by
weight of30% (by weight)H200 is added to the filtrate. Subsequently the mixture is heated under
reflux for 30 minutes with vigorous stirring. After cooling, the mixture is washed with aqueous3% (by
weight) NaHCO3 solution and dried over Na2SO1.The solvent is then evapor
ated in vacuo and the residue kept for 1 hour under an oil pump vacuum at a bath temperature of60 C.
A crystalline substance remains. The yield is 19 parts by weight (75%); melting point:63 to 65 C.

The agents according to the invention may be used as solutions, emulsions,stis- pensions or dusts. The
form of application depends entirely on the purpose for which the agents are being used; in any case it
should ensure a fine distribution of the active ingredient.
For the preparation of solutions to be sprayed direct, organic liquids of boiling point higher than150 C,
e.g. hydrocarbons having boiling points higher than1500C, e.g. tetrahydronaphthalene or alkylated
naphthalenes, or organic liquids having boiling points higher than130do and having one or more than
one functional group, e.g. the keto group, the ether group, the ester group or the amide group, this
group or these groups being attached as substituent(s) to a hydrocarbon chain or being a component of
a heterocyclic ring, may be used as spray liquids.
Aqueous formulations may be prepared from emulsion concentrates, pastes orwettable powders by
adding water. To prepare emulsions the ingredients as such or dissolved in a solvent may be
homogenized in water organic solvents by means of wetting or dispersing agents, e.g., polyethylene
oxide adducts. Concentrates which are suitable for dilution with water may be prepared from active
ingredient, emulsifying, wetting or dispersing agent and possibly solvent.
Dusts may be prepared by mixing or grinding the active ingredients with a solid carrier,erg.,
kieselguhr, talc, clay or fertilizers. The active ingredients may be used mixed with selective herbicides,
plant growth regulating agents or with other pesticides.

Description of GB967081
COMPLETE SPECIFICATION (Thio)-Phosphoric (Phosphonic,Pliosphinic) Acid Esters
and processes for their production
We,FARBENFABRIKEN BAYER AKTIENGSELLSCHAFT, a body corporate organised under the
laws of Germany, of (22c) Leverkusen
Bayerwerk, Germany, do hereby declare the invention, for which we pray that a patent may be granted
to us, and the method by which it is to be performed to be particularly described in and by the
following statment: The present invention is concerned with new and useful phosphorus-containing esters with pesticidal,
especially insecticidal and miticidal, properties and with the production thereof.
In Specification No. 644,616, there is described and claimed a method of preparing an organic
phosphate of the generalformula: -
193/612
EMI1.1
wherein Z is sulphur or oxygen,R11 andRsl are alkyl, aralkyl or aryl radicals andm represents an
integer not greater than 3, which comprises reacting a compound of the generalformula: EMI1.2
with a nitrophenoxide of the general formula:
EMI1.3
wherein X represents an alkali-forming metal, in the presence of a solvent for the alkaliforming metal
nitrophenoxide. These organic phosphates are stated to possess general pestcontrol characteristics.
In Specification No. 655,875, there is described and claimed a pesticidal composition comprising a
mixture of one or more organic phosphates and a carrier therefor, said organic phosphates having the
generalformula:
EMI1.4
in whichR111 andR211 are alkyl, aralkyl or aryl groups, Z1 is a sulphur or oxygen atom, yl is an NH
or N-alkyl group or a sulphur or oxygen atom, and X is a hydrogen or halogen atom or an alkyl, aryl,
alkyloxy, nitro, amino, alkylamino, dialkylamino, acyl, carboalkyloxy or carboaryloxy group, said
carrier comprising at least 50% by weight of the composition, and being such that if the composition is
admixed with or contain water the resulting pH is not greater than 8.5.
We have now found a group of phosphoruscontaining esters which fall within the broad scope of the
formulae of the phosphorus-con taining esters given in the two above-mentioned
Specifications Nos. 644,616 and 655,875 but which are not specifically described in these two
Specifications. The compounds according to the present invention have a greater pesticidal actvity than
those specifically mentioned in Specifications Nos. 644,616 and 655,875.
The new compounds of the present invention may be represented by the general formula:
EMI2.1
in which R1 and R2, which may be the same or different, stand for alkyl or alkoxy radicals containing
1 or 2 carbon atoms, R stands for a methyl or methoxy radical in the 2- or 3position, with the proviso
that R1 and R2 are both alkyl radicals if R is a methyl radical in the 3-position, and X is a sulphur or
oxygen atom.
Dialkyl phosphoric or -thiophosphoric acid esters of 4-nitrophenol have already been described many
times in the literature (compare, for example, G. Schrader "DieEntsvicklung neuer Insektizide auf
Grundlage organischer
Fluor- undPhosphor-Verbindungen", 2nd edition, Verlag Chemie, Weinheim, Bergstrasse, as well as
German Patent No.
S14,152). The insecticidal properties of the named compounds are also known(see, for example,
German Patent Specification No.
811,514). Thus, theO,O-dimethyl-, as well as theO,O-diethyl - 0 - (4-nitrophenyl)-thionophosphoric
acid esters have achieved significance as pesticidal agents. Furthermore, reports have already been
made in the literature about alkyl phosphonicacid-O-alkyl-O-(4-nitro- phenyl) esters and dialkyl
phosphinic acid-O (4-nitrophenyl) esters, as well as about their applicability for the combating of plant
pests.
The disadvantage attached to the abovementioned esters of phosphorus and which renders difficult,
and in many cases even makes impossible, their practical use as pesticidal or plant protective agents, is
the relatively high toxicity of the compounds to warm-blooded animals and the danger connected
therewith for humans and domestic animals.
Various attempts have been made to reduce the toxicity of these products to warm-blooded animals by
the introduction of suitable substituents into the 4-nitrophenyl residue, without the good pesticidal
effect thereby being
Iost. Thus, for example, O,O-dimethyl-O-(chloro-4-nitrophenyl)-thionophosphoric acid ester, which
only possesses a slight toxicity to warm-blooded animals, is already known from
German Patent Specification No. 921,870. In practice, however, this ester has not achieved as great a
significanceas? for example, the
194/612
O,O-dimethyl- or the O,O-diethyl-(4-nitrophenyl)-thionophosphoric acid ester.
In accordance with the present invention it has now been found that (thio)-phosphoric (phosphonic,
phosphinic) acid esters of 2- or 3-methyl-or -methoxy-4-nitrophenol of the general formula:
EMI2.2
in which the symbols have the above said significance, are distinguished by outstanding insecticidal
properties and, in part, by an exceptionally low toxicity for warm-blooded animals. Thus, for example,
the average toxicity(LD5e) of O,O-dimethyl-O-(2-methyl4-nitrophenyl)-thionophosphoric acid ester
amounts to 11000 mg per kg in the case of rats with oral application. However, on the other hand, for
example, plant lice are already killed 100% by0.001% solutions of the ester mentioned. As was further
found, the phosphorus compounds according to the invention are especially suitable for the combating
rice pests, for example, rice stalk borers.
The above-described alteration of the biological properties of the 4-nitrophenyl esters of phosphorus
by the introduction of a methyl or methoxy group into the 2-position of the 4-nitrophenyl residue, is
surprising and makes the compounds valuable as agricultural pesticides.
The inventive (thio)-phosphoric (phosphonic, phosphinic) acid esters of 2- or 3-methyl- or -methoxy4-nitrophenyl are produced according to methods known in principle, i.e. by the reaction of the
corresponding (thio)-phosphoric (phosphonic phosphinic) acid halides (excluding the fluorides) with 2or 3-methyl- or methoxy-4-nitrophenols in the presence of acid-binding agents (e.g. alkali metal
carbonates) or with the salts (preferably alkali metal salts) of 2- or 3-methyl- or methoxy-4nitrophenols. The reaction is preferably carried out in inert, organic solvents, such as hydrocarbons or
lower aliphatic ketones.
Chlorobenzene, toluene, xylene and methyl ethyl ketone have proved to be particularly suitable for the
mentioned purpose.
The products of the process can be applied in the way commonly used for plant protection and
pesticidal agents based on phosphorus esters, i.e. preferably in combination with solid or liquid
extending or diluting agents. As solid extending agents there have proved to be particularly useful
chalk, talc, bentonite and vermiculite, while for the production of liquid formulations there may chiefly
be considered water, possibly in conjunction with a solubiliser (e.g. acetone or dimethyl formamide), as
well as a non-ionic emulsifier.
The following Examples are given for the purpose of illustrating the presentinvention:
EXAMPLE 1
EMI3.1
A solution of 46 g (0.3 mol) of 2-methyl-4nitrophenol in 500 cc of chlorobenzene is mixed with 84 g
(0.6 mol) of powdered potassium carbonate and heated for half an hour with stirring to8090 C. 47 g
(0.33 mol) of dimethyl phosphoric acid chloride are subsequently added dropwise to the mixture
whereby an exothermic reaction sets in which must be somewhat moderated, possibly by cooling. At
the end of the addition of the acid chloride, the reaction mixture is stirred for 2 hours at8090 C. the
separated salts filtered off with suction and the solvent removed by distillation in a vacuum. The
residue is taken up in benzene and first washed in water, later with a 2N solium hydroxide solution for
the removal of unreacted 2-methyl-4-nitrophenol and finally with water until a neutral reaction is
obtained. After drying the benzene layer with sodium sulphate, the solvent is distilled off and there are
obtained 60 g(76.6% of theoretical) of a 97% O,O-dimethyl-O-(2methyl-4-nitrophenyl)-phosphoric
acid ester in the form of a non-distillable red-brown oil.
Analysis:C,H12ONP Calc.: N. 5.36; P 11.86 (mol weight: 261) found: N 5.20; P 11.38
The mean toxicity(LD,,) on rats peros is 100 mg per kg animal. Aphids are killed completely with
0.0001% solutions.
EXAMPLE 2
EMI3.2
195/612
61 g (0.4 mol) of 2-methyl-4-nitrophenol are dissolved in 250 cc of methyl ethyl ketone. The solution
obtained is mixed with 112 g (0.8 mol) of powdered potassium carbonate and heated with stirring
at6070 C. for half an hour.
92 g (0.4 mol) of a 75% solution of dimethyl thiophosphoric acid chloride in xylene is subsequently

COMPLETE SPECIFICATION
New Chlorine- andSulphur-Containsllg Phosphate Ester
We, VEB FARBENFABRIK WOLFEN, of
Wolfen,Kreis Bitterfeld, Germany, a Corporation organised under the laws of Eastern
Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and
the method by which it is to be performed, to be particularly described in and by the
followingstatement:
The present invention is concerned with new, insecticidally-active compounds and with the
preparation thereof.
The chemistry of perchloromethylmercaptan, which is obtained by the chlorination of carbon
disulphide, has recently made great advances, especially since the discovery of the known fungicideN (trichloromethylthio) - tetrahydrophthalimide (Captan).
We have now found that by the addition of perchloromethylmercaptan to dimethyl dichlorovinyl
phosphate, there is obtained the new and insecticidally-active dimethyl (hexchloromethylmercaptoethyl) phosphate of theformula:
EMI1.1
202/612
Since the reaction in question involves a radical reaction mechanism, attempts were made to use
benzoyl peroxide and ultra-violet light as caralysts. It was thereby ascertained that better results are to
be obtained by irradiation with ultra-violet light
The invention also consists in a process for the production of dimethyl (hexachlormethylmercaptoethyp phosphate, wherein perchloro-methyl mercaptan is reacted with dimethyl
dichlorovinyl phosphate in the presence of benzoyl peroxide or while irradiating with ultra-violet light.
In a preferred method of preparing the new compounds, equivalent amounts of perchloromethyl
mercaptan and dimethyl dichlorovinyl phosphate are placed in a reaction vessel made from Uviol
(Trade Mark) glass and subjected to irradiation from an ultra-violet lamp. At the end of the addition
reaction, the unreacted reaction components are removed by vacuum distillarion.
The addition product obtained, which is probably a mixture of the two compounds of the above-given
formulae, possesses a high insecticidal activity and a lower mammalian toxicity than dimethyl
dichlorovinyl phosphate.
It can be used for the formulation of insecticidal compositions by admixture with solid or liquid
diluents or carriers.
The following Examples are given for the purpose of illustrating the presentinvention:
EXAMPLE 1.
A mixture of 186 g. (1 mol) perchloromethyl mercaptan and 221 g. (1 mol) dimethyl dichlorovinyl
phosphate is placed in a reaction vessel made from uviol glass and provided with a cooling jacket and
irradiated with an ultraviolet lamp for 40 hours, with warer cooling.
Thedark yellow reaction product is subsequently freed from unreacted perchloromethyl mercaptan and
dimethyl dichlorovinyl phosphate by distillation in a vacuum. The product can thereby be separated
into three fractions
Boiling point Weight 1. Perchloromethyl mercaptan32"C./3 mm. Hg. 120 g.
2. Dimethyl dichlorovinyl126"C./3 mm. Hg. 140 g.

methylmercapto ethyl)
phosphate
The residue is taken up in ether, washed neutral with water, dried over anhydrous sodium sulphate and
the ether subsequently distilled off. Yield33% of theory.
The product is a dark brown liquid which distils in a vacuum with decomposition.

Abstract:
Abstract of JP52051028
PURPOSE:Selective herbicides of organic phosphates effective for controlling weeds of Gramineae,
broadleaf weeds and perennual weeds in paddy fields by soil or post-emergennce treatment without
exerting damages to applied rice plants.Description:
Description of corresponding document: US4132542
This invention relates to new organic phosphoric acid esters having an excellent herbicidal activity and
their use in controlling harmful weeds. The invention also relates to herbicidal compositions
comprising the organic phosphoric acid ester as an active ingredient and to herbicidal method
employing such compounds.
Canadian Patent Specification No. 710,340 discloses that a compound of the formula ##STR2##
possesses a herbicidal activity.
The novel organophosphosphoric esters of the invention are of the formula ##STR3## in which [email protected] is
lower alkyl (e.g. of up to 6 carbon atoms), cyclohexyl or phenyl;
[email protected] is lower alkyl (e.g., of up to 6 carbon atoms);
[email protected] is alkylene of up to 6 carbon atoms; and
X and Y are independently selected from oxygen and sulfur.
We have discovered that the specific O-phosphoric acid ester type compounds of formula (I) above
exhibit a very good weed-killing effect especially on paddy field weeds, such as gramineous weed,
broadleaf weed and perennial weeds and display selective herbicidal action causing no phytotoxicity to
cultured plants and thus is superior to conventional materials of this type. Particularly, the present
invention is based on the discovery that the specific compounds of formula (I) exhibit superior
herbicidal efficacy when used as either in pre-emergence or post-emergence treatment in paddy fields.
206/612
Preferably, for best activity, [email protected] is C1 -C4 alkyl (namely, methyl, ethyl, n- or isopropyl or n-, iso-,
sec.- or tert.-butyl), cyclohexyl or phenyl, [email protected] is C1 -C4 alkyl and [email protected] is 1-methylpentamethylene
or hexamethylene.
The present invention also provides a process for the preparation of a compound of the formula (I), in
which (a) a phosphoryl chloride of the general formula ##STR4## in which [email protected], [email protected], X and Y have
the meanings stated above, is reacted with a glycolic acid amide of the general formula ##STR5## in
which [email protected] has the meaning stated above, and
[email protected] is hydrogen, an alkali metal atom or an ammonium group, preferably hydrogen, sodium or
potassium, or (b), provided Y is to be sulphur, a thiophosphate of the general formula ##STR6## in
which [email protected], [email protected] and X have the meanings stated above, and
[email protected] is an alkali metal atom or an ammonium group, preferably sodium, potassium or ammonium,
is reacted with a halide of the general formula
[email protected]
(V),
in which
[email protected] has the meaning given above, and
Hal is a halogen atom, preferably chlorine or bromine.
When O-ethyl-S-n-propyldithiophosphoryl chloride and glycolic acid N-(2-methylpiperidide) are used
as starting materials in process variant (a), the course of the reaction can be illustrated by the following
equation: ##STR7##
When potassium O-ethyl-O-(N-2-methylpiperidinocarbonylmethyl)thiophosphate and methyl chloride
are used as starting materials in process variant (b), the course of the reaction can be illustrated by the
following equation: ##STR8##
Examples of the phosphoryl chlorides of the formula (II) include O-ethyl-S-n-propyldithiophosphoryl
chloride, O-isopropyl-S-ethylthiolphosphoryl chloride, O-ethyl-S-methylthiolphosphoryl chloride, Osec.-butyl-S-ethylthiolphosphoryl chloride, O-cyclohexyl-S-methylthiolphosphoryl chloride, O-phenylS-ethylthiolphosphoryl chloride and O-phenyl-O-ethylphosphoryl chloride.
Examples of the glycolic acid amides of the formula (III) include glycolic acid 2-methylpiperidide,
glycolic acid hexamethyleneimide and the potassium or sodium salts thereof.
Process variant (a) may be effected in the presence of an acid-binding agent, especially when [email protected] is
hydrogen. Any of the customary acid acceptors may be used for this purpose, for example a hydroxide,
carbonate, bicarbonate or alcoholate of an alkali metal, or a tertiary amine, for example triethylamine,
diethylaniline or pyridine.
Alternatively, the need for an acid-binding agent can be dispensed with, by employing the glycolic acid
amide in the form of an alkali metal salt or an ammonium salt.
Examples of the thiophosphates of the formula (IV) include potassium, sodium or ammonium O-ethylO-(2-methylpiperidinocarbonylmethyl)dithio-, O-ethyl-O-(2-methylpiperidinocarbonylmethyl)thio-, Oisopropyl-O-(2-methylpiperidinocarbonylmethyl)thio-, O-sec.-butyl-O-(2methylpiperidinocarbonylmethyl)thio-, O-cyclohexyl-O-(2-methylpiperidinocarbonylmethyl)thio- and
O-phenyl-O-(2-methylpiperidinocarbonylmethyl)thiophosphates.
Examples of the halides of the formula (V) include methyl chloride, methyl bromide, ethyl chloride,
ethyl bromide, n-propyl chloride and n-propyl bromide.
The preparative process, whether variant (a) or variant (b), is preferably carried out in the presence of a
solvent or diluent, preferably an inert organic solvent.
Examples of suitable solvents and diluents include water; aliphatic, alicyclic and aromatic
hydrocarbons (which may be chlorinated) such as hexane, cyclohexane, petroleum ether, ligroin,
benzene, toluene, xylene, methylene chloride, chloroform, carbon tetrachloride, ethylene chloride,
207/612
trichloroethylene and chlorobenzene; ethers such as diethyl ether, methyl ethyl ether, di-isopropyl
ether, dibutyl ether, propylene oxide, dioxan and tetrahydrofuran; ketones such as acetone, methyl ethyl
ketone, methyl isopropyl ketone, and methyl isobutyl ketone; nitriles such as acetonitrile, propionitrile
and acrylonitrile; alcohols such as methanol, ethanol, isopropanol, butanol and ethylene glycol; esters
such as ethyl acetate and amyl acetate; acid amides such as dimethyl formamide and dimethyl
acetamide; and sulfones and sulfoxides such as dimethyl sulfoxide and sulfolane. Bases such as
pyridine can serve as a solvent and, in process variant (a), also as acid-binding agents.
Both process variants can be carried out over a wide temperature range. Generally, the reaction is
effected at temperatures between -20 DEG C. and the boiling point of the mixture, preferably between
0 DEG and 100 DEG C. Furthermore, the reaction is preferably effected at normal pressures, although
it is also possible to effect the reaction under an elevated or reduced pressure.
The compounds of the present invention exhibit an excellent weed-killing activity, especially against
weeds that occur in paddy fields, or other crops such as soy beans, sugar beets, cotton etc., for example
gramineous weeds, broadleaved weeds and perennial weeds. By "weeds" in the broadest sense are
meant all unwanted plants growing in cultivated or uncultivated areas.
The present compounds are superior to conventional herbicides and to the structurally analogous
compound of the formula (VI) in that they show an excellent selective herbicidal effect, when used in
appropriate amounts, whether they are used in pre-emergence or in post-emergence treatments.
The compounds of the present invention, when used in appropriate amounts, exhibit little or no
phytotoxicity towards crop plants, especially rice plants. In this respect they appear to be better than
conventional compounds such as PCP or NIP (2,4-dichlorophenyl-4'-nitrophenyl ether), which are
widely used as herbicides in rice fields. The present compounds also show but little toxicity to warmblooded animals.
The present compounds exhibit a non-selective herbicidal action when used in large amounts (say, 6-30
kg of active compound per hectare) but exhibit excellent selective herbicidal action when used in
smaller amounts (say, 0.1-6 kg per hectare). Thus, they are active against the following weeds:
dicotyledons, such as Rotala indica Koehne, Lindernia pyxidaria L., and Polygonum persicaria L.; and
monocotyledons, such as Echinochloa crus-galli Beauvois, Monochoria vaginalis Presl, Eleocharis
acicularis L., Cyperus microiria Steudel, Sagittaria pygmaea Miquel, Potamogeton distinctus Bennett
and Alisma canaliculatum Braun and Bouche.
It should be noted that each of the above-named plants is merely a typical example of the stated genus;
the present compounds are effective against other species of weeds in the same genus.
The active compounds can be converted into the customary formulations, such as solutions, emulsions,
wettable powders, suspensions, powders, dusting agents, foams, pastes, soluble powders, granules,
aerosols, suspension-emulsion concentrates, and formulations used with burning equipment, such as
fumigating cartridges, fumigating cans, fumigating coils and the like, as well as ULV (ultra-lowvolume) cold mist and warm mist formulations.
These formulations may be produced in known manner, for example by mixing the active compounds
with extenders, that is, liquid or solid or liquefied gaseous diluents or carriers, optionally with the use
of surface-active agents, that is, emulsifying agents and/or dispersing agents and/or foam-forming
agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as
auxiliary solvents.
As liquid diluents or carriers, there are preferably used aromatic hydrocarbons, such as xylenes,
toluene, benzene or alkyl naphthalenes, chlorinated aromatic or aliphatic hydrocarbons, such as
chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or
paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers
and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, or
208/612
strongly polar solvents, such as dimethyl formamide, dimethyl sulphoxide or acetonitrile, as well as
water.
By liquefied gaseous diluents or carriers are meant liquids which would be gaseous at normal
temperatures and pressures, for example aerosol propellants, such as halogenated hydrocarbons, for
example freon.
As solid diluents or carriers, there are preferably used ground natural minerals, such as kaolins, clays,
talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, or ground synthetic minerals,
such as highly-dispersed silicic acid, alumina or silicates.
Preferred examples of emulsifying and foam-forming agents include non-ionic and anionic emulsifiers,
such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example
alkylarylpolyglycol ethers, alkyl sulphonates, alkyl suphates and aryl sulphonates as well as albumin
hydrolyzation products; and preferred examples of dispersing agents include lignin sulphite waste
liquors and methyl cellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders,
granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the
formulations.
The active compounds according to the invention, as such or in their formulations, can (in order to
reinforce and supplement their spectrum of action in accordance with the intended use) be combined
with other herbicidal active compounds. The active compounds according to the invention can also be
used as a mixture with other active compounds, such as fungicides, insecticides and acaricides.
The formulations in general contain 0.1 to 95 percent by weight of active compound, preferably 0.5 to
90 percent by weight.
The active compounds can be used as such, in the form of their formulations or in the application forms
prepared therefrom, such as ready-to-use solutions, emulsions, suspensions, powders, pastes and
granules. They may be applied in the customary manner, for example by spraying, atomising, dusting,
scattering, mixing with soil, coating, fumigation, vaporising and watering.
The compositions may be diluted for actual application, and the amount of active compound used can
vary within substantial ranges. In general, the ready-to-use preparations contain 0.01 to 20%,
preferably 0.05 to 10%, by weight, of the active compound.
The active compounds can also be applied using the ULV method, whereby it is possible to apply
compositions that are 95% by weight active compound or even to use the active compound by itself.
In general, the active compound is applied to an area of agriculture in an amount of 0.1 to 10 kg per
hectare, preferably 0.3 to 6 kg per hectare. However, it is possible to employ application rates outside
the broader range.
The present invention also provides a herbicidal composition containing as active ingredient a
compound of the present invention in admixture with a solid or liquefied gaseous diluent or carrier or
in admixture with a liquid diluent or carrier containing a surface-active agent.
The present invention also provides a method of combating weeds which comprises applying to the
weeds, or to a habitat thereof a compound of the present invention alone or in the form of a
composition containing as active ingredient a compound of the present invention in admixture with a
diluent or carrier.
The present invention further provides crops protected from damage by weeds by being grown in areas
in which immediately prior to and/or during the time of the growing a compound of the present
invention was applied alone or in admixture with a diluent or carrier.
209/612
It will be seen that the usual methods of providing a harvested crop may be improved by the present
invention.
The herbicidal compositions of this invention are illustrated by the following Examples, in which the
active compounds are identified by the number of the corresponding preparative Example. Parts are by
weight.
EXAMPLE (I)
Fifteen parts of compound No. 2, 80 parts of a mixture of siliceous earth and kaolin (at a ratio of 5:1)
and 5 parts of an emulsifier (a polyoxyethylene alkylphenylether) were mixed by pulverization, thereby
forming a wettable powder. The resulting wettable powder was diluted with water and applied by
spraying.
EXAMPLE (II)
Thirty parts of compound No. 6, 30 parts of xylene, 30 parts of methylnaphthalene and 10 parts of a
polyoxyethylene alkylphenylether were mixed by stirring, thereby forming an emulsifiable concentrate.
The resulting concentrate was diluted with water before being applied by spraying.
EXAMPLE (III)
Two parts of compound No. 4 and 98 parts of a mixture of talc and clay (at a ratio of 1:3) were mixed
by pulverization, thereby forming a dusting agent.
EXAMPLE (IV)
1.5 parts of compound No. 3, 0.5 part of isopropyl hydrogen phosphate (PAP), and 98 parts of a
mixture of talc and clay (at a ratio of 1:3) were mixed by pulverization, thereby forming a dusting
agent.
EXAMPLE (V)
Twenty-five parts of water were added to a mixture comprising 10 parts of compound No. 1, 10 parts
of bentonite, 78 parts of a mixture of talc and clay (at a ratio of 1:3) and 2 parts of lignin sulfonate.
The resulting mixture was compacted well and then finely divided into granular form of 20-40 mesh,
by means of an extruder granulator, and dried at 40 DEG-50 DEG C., thereby forming a granular agent.
EXAMPLE (VI)
Ninety-five parts of clay particles having a particle size distribution of0.2 to 2 mm were charged into a
rotary mixer, and 5 parts of compound No. 7 dissolved in an organic solvent were sprayed onto said
particles in the mixer during rotation. After the product had been rendered homogeneous, it was dried
at 40 DEG-50 DEG C., thereby giving a granular agent.
EXAMPLE (VII)
0.5 part of compound No. 8, 20 parts of a mixture of high-boiling-point aromatic compounds and 9.5
parts of kerosine were mixed by stirring, thereby giving an oil preparation.
The herbicidal activity of the present compounds is illustrated by the following biotest Examples.
Again, each of the compounds of this invention is identified by the number of the corresponding
preparative Example.
EXAMPLE A
Pre-emergence treatment under flooded conditions against paddy-field weeds (pot test)
210/612
Production of the active-compound preparation
Solvent: 5 parts by weight of acetone
Emulsifier: 1 part by weight of benzyloxypolyglycol ether
The preparation of the active compound was obtained by mixing one part by weight of the active
compound with the above-stated amounts of solvent and emulsifier. The emulsifiable concentrate
obtained in this manner was then diluted with water to the required concentration.
Test Method:
Wagner pots (0.0002 are) were charged with soil from a paddy field. Two rice plants (Kinmaze variety)
at the two- or three-leaved stage (about 10 cm high) were transplanted into each pot. In addition,
Echinochloa crus-galli, Cyperus sp., Eleocharis acicularis L. and seeds of various broad-leaved weeds
(including Monochoria vaginalis Presl, Rotala indica Koehne, and Lindernia pyxidaria L.) were also
planted and the whole was maintained in a wet condition. Two days after transplantation, each pot was
flooded with water to a depth of 3 cm. The active-compound preparation was then applied at a
prescribed dosage.
After this treatment, water was allowed to leak out of each pot for two days at a rate of 2-3 cm per day.
Thereafter, each pot was maintained in a flooded condition to a depth of 3 cm. Four weeks after the
treatment with the active-compound preparation, the herbicidal efficacy and the phytotoxicity towards
the rice plants were evaluated, in comparison with untreated control pots, on the following scales.
Herbicidal efficacy
5 - more than 95%
4 - more than 80%
3 - more than 50%
2 - more than 30%
1 - more than 10%
0 - 10% or less
Phytotoxicity towards rice plants
5 - more than 90% (plant completely injured)
4 - more than 50%
3 - more than 30%
2 - 30% or less
1 - less than 10%
0 - 0% (no phytotoxicity)

EXAMPLE B
Post-emergence treatment under flooded conditions against paddy-field weeds (pot test)
Production of the active-compound preparation
The active-compound preparation was obtained in the manner described in Example A.
Test method
Wagner pots (0.0002 are) were charged with soil from a paddy field. Two rice plants (Kinmaze variety)
at the two- or three-leaved stage (about 10 cm high) were transplanted into each pot. In addition,
Echinochloa crus-galli, Cyperus sp., Eleocharis acicularis L. and seeds of various broad-leaved weeds
(including Monochoria vaginalis Presl, Rotala indica Koehne and Lindernia pyxidaria L.) were also
planted and the whole was maintained in a wet condition.
The active-compound preparation was applied when the Echinochloa crus-galli had grown to the twoleaved stage (about 7-9 days after being planted). At the time of the treatment with the activecompound preparation, each pot was flooded to a depth of 6 cm.
After this treatment, water was allowed to leak from each pot for two days at a rate of 2 to 8 cm per
day. Thereafter, each pot was maintained in a flooded condition, to a depth of 3 cm. Four weeks after
treatment, the herbicidal efficacy and the phytotoxicity towards the rice plants were evaluated, in
comparison with untreated control pots, on the scales given in Example A.
The results obtained are given below in Table B.

EXAMPLE 1 ##STR11##
2.8 g of anhydrous potassium carbonate were added to a solution comprising 4.4 g (0.02 mole) of Oethyl-S-n-propyldithiophosphoryl chloride, 3.2 g (0.02 mole) of glycolic acid-2-methylpiperidide and
20 ml of toluene. The resulting solution was then stirred at 30-35 DEG C. for 18 hours. After
completion of the reaction, the reaction mixture was cooled to room temperature and washed with
water, a 5 % aqueous potassium hydroxide solution and water in that order. The organic layer was
separated and collected, and then dried with anhydrous sodium sulfate. After removal of toluene by
distillation there were obtained 5.5 g of O-ethyl-S-n-propyl-O-(2-methylpiperidinocarbonylmethyl)
phosphorodithioate. This final product had a refractive index [email protected] of 1.5310.
EXAMPLE 2 ##STR12##
To a solution comprising 4.1 g (0.02 mole) of O-isopropyl-S-ethylthiophosphoryl chloride, 3.2 g (0.02
mole) of glycolic acid-2-methylpiperidide and 20 ml of toluene there were added 2.1 g (0.02 mole) of
triethylamine at 20-30 DEG C., and the resulting solution was stirred for 1 hour. Thereafter, it was
stirred at 50-60 DEG C. for 1 hour and then at 80 DEG C. for 1 hour. After completion of the reaction,
the reaction mixture was cooled to room temperature and washed with water, dilute hydrochloric acid,
a 5% aqueous sodium hydroxide solution and water in that order. The organic layer was separated and
collected. By following the procedure of Example 1 there were obtained 5.5 g of O-isopropyl-S-ethyl-
213/612
O-(2-methylpiperidonocarbonylmethyl) phosphorothioate. This product had a refractive index [email protected]

Description of corresponding document: US4084952
BACKGROUND OF THE INVENTION
A broad range of alkyl(aminocarbonyl)phosphonate salts is disclosed in U.S. Pat. No. 3,846,512. These
compounds are extremely useful as plant growth regulants.
The presence of undesired vegetation in rice is an especially important problem for the world at this
time. Faced with the current world situation, wherein food shortages are acute in many different areas,
it is most important not to lose a portion of a valuable crop such as rice because of the presence of this
undesired vegetation. In particular, two kinds of herbaceous weeds, arrowhead, Sagittaria sp. and
nutsedge, Cyperus serotinus or rotundus are especially troublesome for rice crops. In the past, these
herbaceous weeds have been extremely difficult to control. Thus, a need exists for a particularly
effective compound which will control the growth of these weeds and prevent them from damaging a
significant part of the rice crop.
SUMMARY OF THE INVENTION
According to this invention, it has unexpectedly been discovered that a compound of Formula I may be
utilized for the post-harvest control of arrowhead, Sagittaria sp. and nutsedge Cyperus serotinus or
rotundus. ##STR1## wherein R1 is alkyl of 1 through 8 carbon atoms, chloroalkyl of 1 through 8
carbon atoms containing up to 3 chlorine atoms, bromoalkyl of 1 through 8 carbon atoms containing up
to 3 bromine atoms, alkoxy alkyl of from 3 through 10 carbon atoms, total, alkenyl of 2 through 8
carbon atoms, alkynyl of 3 through 4 carbon atoms, phenyl or benzyl;
215/612
R2 and R3 can be the same or different and each can be hydrogen, alkyl of 1 through 4 carbon atoms,
hydroxy alkyl of 2 through 4 carbon atoms, alkenyl of 3 through 4 carbon atoms, alkynyl of 3 through
4 carbon atoms; R2 and R3 can be taken together to form a ring wherein R2 and R3 taken together are -(CH2)2 --O--(CH2 O2 -- or --(CH2)n -- where n is 4, 5 or 6 or one of R2 and R3 can be ##STR2##
where R4 is hydrogen or alkyl of 1 through 4 carbon atoms and R5 is hydrogen or alkyl of 1 through 4
carbon atoms, and
M is hydrogen, sodium, lithium, potassium, calcium, magnesium, zinc, manganese, barium or
##STR3## where R6, R7 and R8 can be the same or different and each can be hydrogen, alkyl of 1
through 4 carbon atoms or hydroxy alkyl of 2 through 4 carbon atoms; and R9 is hydrogen, alkyl of 1
through 12 carbon atoms, ##STR4## where R4 is hydrogen or alkyl of 1 through 4 carbon atoms and
R5 is hydrogen or alkyl of 1 through 4 carbon atoms or benzyl.
Preferred for their high biological activity are those compounds of formula I where, independently:
(a) R1 is alkyl of 1 through 4 carbon atoms or alkenyl of 3 through 4 carbon atoms,
(b) R2 and R3 are both equal to hydrogen,
(c) M is ammonium or an alkali metal such as sodium, lithium or potassium.
More preferred for their higher activity are those compounds of formula I where R1 is alkyl of 1
through 4 carbon atoms, R2 and R3 are both hydrogen and M is ammonium or an alkali metal such as
sodium, lithium or potassium.
Specifically preferred for their outstanding herbicidal activity are:
(a) Ammonium ethyl (aminocarbonyl) phosphonate m.p. 173 DEG-176 DEG C
(b) Ammonium methyl (aminocarbonyl) phosphonate m.p. 148 DEG-152 DEG C.
PREPARATION OF THE COMPOUND
The compounds of the instant invention may be prepared according to the process disclosed in U.S.
Pat. 3,846,512, the disclosure of which is herein incorporated by reference.
Basically, the process involves the following equation: ##STR5##
FORMULATION OF THE COMPOUNDS
The growth controlling compositions of the present invention can be prepared by admixing at least one
of the compounds of this invention with pest control adjuvants or modifiers to provide compositions in
the form of dusts, water-soluble powders, solutions, granules or pellets.
Compositions of the invention may contain as a conditioning agent, one or more surface-active agents,
sometimes called surfactants, in amounts sufficient to render a given composition containing the
compound of this invention readily soluble in water or capable of wetting foliage efficiently.
The surface-active agent used in this invention can be a wetting, dispersing or an emulsifying agent
which will assist dispersion and solution of the active compound. The surface-active agent or surfactant
can include such anionic, cationic and non-ionic agents as have heretofore been generally employed in
plant control compositions of similar type. Suitable surface-active agents are set forth, for example, in
"Detergents and Emulsifiers", 1975 Annual by John W. McCutcheon, Inc.
In general, less than 10% by weight of the surface-active agent will be used in compositions of this
invention and ordinarily the amount of surface-active agents will range from 1-5% but may even be
less than 1% by weight.
Additional surface-active agents can be added to the formulations to increase the ratio of
surfactant:active ingredient up to as high as 5:1 by weight. Such compositions may have a greater
effectiveness than can be expected from a consideration of the activity of the components used
separately. When used at higher rates, it is preferred that the surfactant be present in the range of onefifth to five parts surfactant for each one part of active agent.
WATER-SOLUBLE POWDERS
216/612
Water-soluble powders are compositions containing the water-soluble active material, an inert solid
extender which may or may not be water-soluble, and optionally one or more surfactants to provide
rapid wetting and solution. A buffer, which may also function as an extender, can be present to
improve formulation stability and control the pH of the final spray solution.
The classes of extenders suitable for the water-soluble powder formulations of this invention are the
natural clays, diatomaceous earth, synthetic mineral fillers derived from silica and silicate, starch,
sugar, and inorganic salts. Most preferred fillers for this invention are kaolinites, attapulgite clay,
montmorillonite clays, synthetic silicas, synthetic magnesium silicate, calcium sulfate dihydrate, and
disodium hydrogen phosphate.
Suitable surfactants for use in such compositions are those listed by J. W. McCutcheon in "Detergents
and Emulsifers", 1975 Annual. Among the more preferred surfactants are the non-ionic and anionic
types, and those most suitable for the preparation of the dry, soluble products of this invention are solid
forms of compounds known to the art as wetters and dispersants. Occasionally a liquid, non-ionic
compound classified primarily as an emulsifier may serve as both wetter and dispersant.
Most preferred wetting agents are alkylbenzene- and alkylnaphthalene-sulfonates, sulfated fatty
alcohols, amines or acid amides, long-chain acid esters of sodium isethionate, esters of sodium
sulfosuccinate, sulfated or sulfonated fatty acid esters, petroleum sulfonates, sulfonated vegetable oils
and ditertiary acetylenic glycols. Preferred dispersants are methylcellulose, polyvinyl alcohol lignin
sulfonates, polymeric alkylnaphthalenesulfonates, sodium naphthalenesulfonate, polymethylene
bisnaphthalenesulfonate, and sodium N-methyl-N-(long chain acid)taurates.
Wetting and dispersing agents in these preferred water-soluble compositions of this invention are
usually present at concentrations of from about 0.5 weight percent to 5 weight percent. The inert
extender then completes the formulation. Where needed, 0.1 weight percent to 1.0 weight percent of
the extender may be replaced by a corrosion inhibitor or an anti-foaming agent or both.
Thus, water-soluble formulations of the invention will contain from about 25 to 95 weight percent
active material, from 0.5 to 2.0 weight percent wetting agent, from 0.25 to 0.5 weight percent
dispersant, and from 4.25 to 74.25 weight percent inert extender, as these terms are described above.
When the water-soluble powder contains a corrosion inhibitor or an anti-foaming agent or both, the
corrosion inhibitor will not exceed about 1 percent of the composition, and the anti-foaming agent will
not exceed about 0.5 percent by weight of the composition, both replacing equivalent amounts of the
inert extender.
SOLUTION CONCENTRATES
The aqueous solution concentrates are prepared by mixing a water-soluble active compound of this
invention with water. A portion of the water may be replaced with methanol, ethanol, isopropanol,
ethylene glycol, cellosolve or methyl cellosolve. Surfactants and buffering agents can optionally be
present.
These aqueous solution concentrates will contain from 15 to 60 percent active ingredient and from 40
to 85 percent water or mixture of water and hydroxylated organic solvent. Surfactants, corrosion
inhibitors, buffering and antifoam agents may also be included in which case they may replace up to 10
percent of the solvent system.
DUSTS
Dusts are dense powder compositions which are intended for application in dry form, in accordance
with the preferred compositions and methods of the invention. Dusts are characterized by their freeflowing and rapid settling properties so that they are not readily windborne to areas where their
presence is not desired. They contain primarily an active material and a dense, free-flowing, solid
extender.
217/612
Their performance is sometimes aided by the inclusion of a wetting agent, and convenience in
manufacture frequently demands the inclusion of an inert, adsorptive grinding aid. For the dust
compositions of this invention, the inert extender may be either of vegetable or mineral origin, the
wetting agent is preferably anionic or non-ionic and suitable adsorptive grinding aids are of mineral
origin.
Suitable classes of inert solid extenders for use in the dust compositions are those organic or inorganic
powders which possess high bulk density and are very free-flowing. They are also characterized by
possessing relatively low surface areas and are poor in liquid adsorption. Suitable classes of grinding
aids are natural clays, diatomaceous earths, and synthetic mineral fillers derived from silica or silicate.
Among ionic and non-ionic wetting agents, the most suitable are the members of the group known to
the art as wetting agents and emulsifiers. Although solid agents are preferred because of ease of
incorporation some liquid non-ionic agents are also suitable in the dust formulations.
Preferred inert solid extenders for the dusts of this invention are micaceous talcs, pyrophyllite, dense
kaolin clays, tobacco dust and ground calcium phosphate rock.
Preferred grinding aids are attapulgite clay, diatomaceous silica, synthetic fine silica and synthetic
calcium and magnesium silicates. Preferred wetting agents are those previously described under watersoluble powder formulations.
The inert solid extenders in the dusts of this invention are usually present in concentration of from
about 30 to 90 weight percent of the total composition. The grinding aid will usually constitute 5 to 50
weight percent of the composition, and the wetting agent will constitute from 0 to 1.0 weight percent of
the composition. Dust compositions can also contain other surfactants such as dispersing agents in
concentrations of up to about 0.5 weight percent.
The water-soluble powders described above can also be used in the preparation of dusts. While such
water-soluble powders could be used directly in dust form, it is more advantageous to dilute them by
blending with the dense dust diluent. In this manner, dispersing agents, corrosion inhibitors, and antifoam agents may also be found as components of a dust.
Thus, the dust compositions of this invention will comprise about 5 to 20 weight percent active
material, 5 to 50 weight percent adsorptive filler, 0 to 1.0 weight percent wetting agent, and about 30 to
90 weight percent dense, free-flowing dust diluent, as these terms are used herein. Such dust
formulations can contain, in addition, minor amounts of dispersants, corrosion inhibitors, and anti-foam
agents, derived from the water-soluble powders used to make the dusts.
GRANULES AND PELLETS
Under some circumstances it may be advantageous to apply the compounds of this invention in the
form of granules or pellets. Suitable carriers are natural clays, some pyrophyllites and vermiculites.
Wetting agents of the type listed by J. W. McCutcheon in "Detergents and Emulsifiers", 1975 Annual
can also be present to aid leaching of the active component.
One method of preparation suitable for both granules and pellets involves blending the active
ingredient with clays, water-soluble salts, surfactants and a small amount of water. After pelleting
and/or granulating, the formulation is dried prior to use. A second method suitable for the preparation
of granules formulation involves spraying a solution of the active material on porous, adsorptive,
preformed clay or vermiculite granules. Surfactants listed by McCutcheon can also be included in the
spray solution. After drying, the granules are ready for application.
The preferred granules or pellets will contain about 5 to 30 weight percent of active material, about 0 to
5 weight percent wetting agent and about 65 to 95 weight percent inert mineral carrier.
UTILITY
The carbamoylphosphonic salts of this invention may be used to control certain persistent weeds in rice
paddies after the harvest of one rice crop and prior to the planting of the next. These weeds, such as
218/612
arrowhead and nutsedge are not controlled by currently used selective rice herbicides. When sprayed
on the foliage of the weeds while they are growing, but after rice harvest, the phosphonates of this
invention cause retardation and prevent bud break on the vegetative propagules (stolons or tubers) of
these species. This effectively controls the plant the following season. These chemicals have little or no
effect on plants through the soil and cause no reaction in the following crop.
The compounds may be applied at rates of 1 to 20 kg/ha in sufficient carrier to distribute them
uniformly over the leaves of the weeds. Treatment must be applied while the weeds are green and
growing to insure that it will be translocated to the stolons or tubers. However, it must not be applied
before the crop is harvested.
EXAMPLE 1
Arrowhead, Sagittaria sp., was treated with ammonium ethyl(aminocarbonyl)phosphonate after water
had been drained from experimental rice pots at the rate of approximately 2-1/2 kg/ha. This treatment
caused marked growth retardation and prevented regrowth in the pots.
EXAMPLE 2
Nutsedge, Cyperus serotina, growing in experimental pots was treated with rates of ammonium
ethyl(aminocarbonyl)phosphonate at rates of 2-1/2, 5 and 10 kg/ha. Two and one-half months later the
tubers were dug from treated and control pots and their germination determined. The results are shown
below.

Abstract of JP55141495
NEW MATERIAL:The title compound of formula I (R is methyl or ethyl group). EXAMPLE:The
compound of formula I. USE:A nematocide against soil nematodes of the genera Heterodera (cyst
nematode), Pratylenchus (root leison nematode), and Meloidogyne (root-knot nematode), and
Aphelenchoides besseyi Christie (rice white-tip nematode), applicable during the growth of crops, with
safety and low toxicity to men and cattle, without phytotoxicity. PROCESS:A phosphorodithioate of
formula II (M is alkali metal; A is isopropyl, methyl, or ethyl group) is reacted with a halogen
compound of the formula Hal.B (Hal is halogen; B is isopropyl, methyl, or ethyl group, and when A is
isopropyl group B is methyl or ethyl group). Alternatively, a phosphorochloridothioate of formula IV is
reacted with a mercaptan of the formula HSB in the presence of a deacidification agent.Description:
Description of corresponding document: US4273769
This invention relates to an O-ethyl S-alkyl S-isopropyl phosphorodithiolate represented by the general
formula (I), ##STR1## wherein R represents methyl or ethyl group. It relates also to a nematocidal
composition comprising said dithiolate compound as an active ingredient.
The present compound represented by the general formula (I) is a novel nematocidal compound not
described in the literature, which can control a wide variety of harmful nematoda and exhibits little
phytotoxicity.
The nematocides in general use at present include D--D (a mixture of dichloropropene and
dichloropropane), EDB (ethylene dibromide), DBCP (1,2-dibromo-3-chloropropane), chloropicrin and
the like.
All of these chemicals diffuse as a gas through the soil and the nematoda die by contact with the gas.
However, in order to ensure the nematocidal effect, covering or water sealing of the field is necessary
for 7 to 14 days after application of the chemicals. Further, if a crop is transplanted or sowed while the
gas is still remaining, it will suffer from chemical injury. Accordingly, the field must be left as it is for
220/612
a long period after application of the chemicals or subjected to frequent degassing to remove the gas
from the soil. Owing to the non-cultivation period which is required or the troublesome degassing
work, an optimum sowing or planting time is often missed.
Beside the above-noted disturbance in effective utilization of the field owing to the chemical injury, a
high toxicity of chloropicrin gives rise to the pollution problem and other above-noted chemicals have
a disadvantage of high controlling chemical's cost per unit area.
The present inventors performed an investigation on the nematocidal effect of a series of
dithiolphosphate esters and as a result found that, as will become evident from the Examples herein
described, a distinguished nematocidal effect is exhibited by an ester in which the alkyl in the O-alkyl
linkage is ethyl, the alkyl in one S-alkyl linkage is isopropyl, and the alkyl in the other S-alkyl linkage
is methyl or ethyl, as compared with other esters having other alkyls closely related to those in the
former ester. Based on this finding, the present invention has been accomplished.
The compound of this invention is a compound which is safe, free from chemical injury, applicable
even during the vegetative period of the crops, is of high nematocidal activity, and of low toxicity to
man and animals. As contrasted to the conventional notion about the use of commercial nematocides,
the active ingredient of this invention is a distinguished nematocidal compound which is applicable to
the plant at any stage of growth.
The nematocide of this invention is effective in controlling a wide variety of nematoda including not
only soil nematoda such as cyst nematode, root-knot nematode and root-lesion nematode, but also other
nematoda such as rice white-tip nematode.
These O-ethyl S-alkyl S-isopropyl phosphorodithiolates are synthesized as described below.
The O-ethyl S-alkyl S-isopropyl phosophorodithiolates represented by the general formula (I) can be
prepared by any of the following methods A, B, C, D and E.
A. Synthesis by the reaction of a dithiophosphoric acid salt represented by the general formula (II),
##STR2## (wherein M represents an alkali metal atom such as, for example, potassium or sodium and

Abstract:
Abstract of JP58032890
NEW MATERIAL:A derivative of formulaI(R1 is lower alkyl; R2 is 2,4-dichlorophenyl, 4tolyfluoromethylphenyl). EXAMPLE:o,o-Diisopropylphosphonomethyl alpha=4-(2',4'dichlorophenoxy)phenoxypropionate. USE:Herbicide with high selectivity for rice and wheat.
PREPARATION:The condensation reaction between a hydroxymethylphosphonic ester derivative such
as o,o-diisopylhydroxymethyl phsophonate and an acid chloride of formula III such as alpha-4-(2',4'dichlorophenoxy)phenoxypyorpionyl chloride is conducted in a solvent such as chloroform in the
presence of a base such as pyridine.Description:
Description of corresponding document: US4470841
The present invention relates to organic phosphorous compounds, and their production and use. More
particularly, it relates to organic phosphorus compounds of the formula: ##STR2## wherein R1 is a C1
-C4 alkyl group, a phenyl group or a C1 -C4 alkoxy group, R2 is a C1 -C4 alkyl group, R3 and R4,
which are the same or different, are each a hydrogen atom, a C1 -C4 alkyl group or a phenyl group and
R5 is a 2,4-dichlorophenyl group, a 4-trifluoromethylphenyl group or a 5-trifluoromethylpyridin-2-yl
group, and their production and use a herbicides.
Among the organic phosphorus compounds (I), preferred are those wherein R1 is a C1 -C2 alkyl group,
a phenyl group or a C1 -C4 alkoxy group, R2 is a C1 -C4 alkyl group, R3 is a hydrogen atom, a C1 -C3
alkyl group or a phenyl group, R4 is a hydrogen atom or a methyl group and R5 is a 2,4-dichlorophenyl
group, a 4-trifluoromethylphenyl group or a 5-trifluoromethylpyridin-2-yl group.
It is known that certain kinds of 2-(substituted pheoxy)propionic acid derivatives, for instance,
diclofopmethyl (i.e. methyl 2-[4-(2,4-dichlorophenoxy)phenoxy]propionate), metriflufen-methyl (i.e.
methyl 2-[4-(4-trifluoromethylphenoxy)phenoxy]propionate) and fluazifop-butyl (i.e. butyl 2-[4-(5trifluoromethyl-2-pyridyloxy)phenoxy]propionate), show a herbicidal activity against Graminaceous
weeds (cf. U.S. Pat. No. 3,954,442, GB No. 1519334B, GB No. 2015995A, etc.). However, these
230/612
known compounds have a poor selectivity between said harmful weeds and the important useful plants
such as rice plant.
As a result of the extensive study, it has now been found that the organic phosphorus compounds (I) of
the invention exhibit a prominent herbicidal potency against Graminaceous weeds germinated in the
paddy field, particularly barnyard grass (Echinochloa crus-galli), while exerting no material
phytotoxicity to the transplanted paddy rice. It has also been found that the organic phosphorus
compounds (I) of the invention show an excellent herbicidal activity against the Graminaceous weeds
in the crop field by pre-emergence soil treatment as well as post-emergence foliar treatment.
Particularly, in the post-emergence treatment, they show a strong herbicidal activity against a variety of
Graminaceous weeds such as wild oat (Avena fatua), barnyard grass, green foxtail (Setaria viridis),
blackgrass (Alopecurus myosuroides), downy brome (Bromus tectorum), johnsongrass (Sorghum
halepense), large crabgrass (Digitaria sanguinalis), annual bluegrass (Poa annua), volunteer corn (Zea
mays), etc. without any material phytotoxicity to broad-leaved crop plants such as soybeans, cotton or
sugarbeet, etc. Besides, they can be safely applied to the wheat fields to exterminate or prevent wild
oat, barnyard grass, green foxtail, blackgrass, downy brome, etc. germinated therein. Thus, the organic
phosphorus compounds (I) can be used as herbicides applicable for the fields of crops and vegetables,
etc.
The organic phosphorus compound (I) can be produced by reacting a hydroxyl compound of the
formula: ##STR3## wherein R1, R2, R3 and R4 are each as defined above with an acid halide of the
formula: ##STR4## wherein X is a halogen atom (e.g. chlorine, bromine) and R5 is as defined above in
an inert solvent (e.g. water, chloroform, ether, benzene, toluene) in the presence of a base such as an
organic tertiary amine (e.g. pyridine, triethylamine, N,N-dimethylaniline) or an inorganic base (e.g.
sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate). The base may be
employed in an amount of 1 to 2 equivalents to the hydroxyl compound (II).
The reaction proceeds ordinarily at a temperature of -70 DEG C. to 50 DEG C. and can be
accomplished within a period of 10 minutes to 24 hours, although it varies depending upon the starting
materials. By usual work-up, the objective organic phosphorus compound (I) is obtainable in a high
yield. If necessary, however, purification such as column chromatography may be applied.
The hydroxyl compound (II) used as the starting material in the above reaction can be produced
according to the method as described in Howben-Weyl: Methoden der Organischen Chemie, 12 (1), p.
475 (1964). Namely, it can be produced from the reaction between aldehydes (or ketones) and
phosphonic acid or its ester.
Alternatively, the organic phosphorus compound (I) can be obtainable by reacting an acid ester of the
formula: ##STR5## wherein X' is a halogen atom (e.g. chlorine, bromine) and R1, R2, R3 and R4 are
each as defined above with a hydroxyphenyl ether of the formula: ##STR6## wherein R5 is as defined
above in an organic solvent such as ketones (e.g. acetone, methylisobutylketone), dimethylformamide
or diethylformamide in the presence of a base (e.g. sodium carbonate, potassium carbonate). The base
may be employed in an amount of 1 to 1.5 equivalents to the acid ester (IV).
The reaction proceeds ordinarily at a temperature of 50 DEG C. to the refluxing temperature of the
solvent and can be accomplished within a period of 3 to 12 hours, although it varies depending upon
the starting materials. By usual work-up, the objective organic phosphorus compund (I) is obtainable in
a high yield. If necessary, however, purification such as column chromatography may be applied.
Some embodiments of the procedures for production of the organic phosphorus compounds (I) are
illustratively shown in the following Examples.

In the practical usage of the organic phosphorus compounds (I), they may be applied as such or in any
composition form such as wettable powders, emulsifiable concentrates, granules, fine granules or dusts.
For formulation of those compositions, a solid or liquid carrier or diluent may be used. As for the solid
carrier or diluent, there may be exemplified mineral powders (e.g. kaolin, bentonite, montmorillonite,
talc, diatomaceous earth, mica, vermiculite, gypsum, calcium carbonate, apatite, synthetic hydrated
silica), vegetable powders (e.g. soybean powder, wheat flour, wooden powder, tobacco powder, starch,
crystalline cellulose), high molecular weight compounds (e.g. petroleum resin, polyvinyl chloride,
dammar gum, ketone resin), alumina, wax and the like. As for the liquid carrier or diluent, there may be
exemplified alcohols (e.g. methanol, ethanol, ethylene glycol, benzyl alcohol), aromatic hydrocarbons
(e.g. toluene, benzene, xylene, methylnaphthalene), halogenated hydrocarbons (e.g. chloroform, carbon
tetrachloride, monochlorobenzene), ethers (e.g. dioxane, tetrahydrofuran), ketones (e.g. acetone,
methylethylketone, isophorone, cyclohexanone), esters (ethyl acetate, butyl acetate, ethylene glycol
acetate), acid amides (e.g. dimethylformamide), nitriles (e.g. acetonitrile), ether alcohols (e.g. ethylene
glycol ethyl ether), water and the like.
A surface active agent used for emulsification, dispersion or spreading may be any of the non-ionic,
anionic, cationic and amphoteric type of agents. Examples of the surface active agent include
polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene fatty acid esters,
sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, oxyethyleneoxypropylene
polymers, polyoxyethylene alkyl phosphates, fatty acid salts, alkyl sulfates, alkyl sulfonates, alkylaryl
sulfonates, alkyl phosphates, polyoxyethylene alkyl sulfate, quaternary ammonium salts, and the like.
But the surface active agent is not of course limited to these compounds. And, if necessary, gelatin,
casein, sodium alginte, starch, agar, polyvinyl alcohol, ligninsulfonic acid, isopropyl acid phosphate,
alginates or the like may be used as auxiliary agents.
The organic phosphorus compounds (I) of the invention may be used together with other herbicides to
improve their activity as herbicides, and in some cases, a synergistic effect can be expected. As the
herbicides to be mixed with, there may be given 2,4-dichlorophenoxyacetic acid, sodium 5-[2-chloro-4(trifluoromethyl)phenoxy]-2-nitrobenzoate, 2-chloro-4-ethylamino-6-isopropylamino-s-triazine, 2methylthio-4,6-bis(isopropylamino)-s-triazine, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, 3-[4-(4chlorophenoxy)phenyl]-1,1-dimethylurea, 3-(.alpha.,.alpha.,.alpha.-trifluoro-m-tolyl)-1,1-dimethylurea,
isopropyl N-(3-chlorophenyl)-carbamate, 3,4-dichloropropionanilide, 3-cyclohexyl-5,6trimethyleneuracil, O-ethyl O-(5-methyl-2-nitrophenyl)-N-sec-butylphosphoramidothioate, 3isopropyl-1H-2,1,3-benzothiadiazin-(4)-3H-one-2,2-dioxide, disodium methanearsonate, etc.
In the herbicidal composition of the invention, the content of the organic phosphorus compounds (I)
may be from 0.5 to 90% by weight, preferably from 1 to 80% by weight.
Practical embodiments of the herbicidal composition according to the invention are illustratively shown
in the following examples wherein parts and % are by weight. The compound number of the active
ingredient corresponds to the one in Table 1.
FORMULATION EXAMPLE 1
Forty parts of Compound No. 3, 2 parts of polyoxyethylene alkylaryl ether, 30 parts of synthetic
hydrated silica and 28 parts of diatomaceous earth are well mixed while being powdered to obtain a
wettable powder.
235/612
FORMULATION EXAMPLE 2
Ten parts of Compound No. 6, 7 parts of polyoxyethylene alkylaryl ether, 3 parts of alkylarylsulfonate
and 80 parts of xylene are well mixed while being powdered to obtain an emulsifiable concentrate.
FORMULATION EXAMPLE 3
One part of Compound No. 9, 1 part of synthetic hydrated silica, 5 parts of lignin sulfonate and 93 parts
of kaolin are well mixed while being powdered. The mixture is then kneaded with water, granulated
and dried to obtain granules.
FORMULATION EXAMPLE 4
Forty parts of bentonite, 5 parts of lignin sulfonate and 55 parts of kaolin are well mixed while being
powdered. The mixture is then kneaded with water, granulated and dried to obtain granules containing
no active ingredient. Five parts of Compound No. 17 are immersed therein to obtain a granule.
FORMULATION EXAMPLE 5
Three parts of Compound No. 19, 0.5 part of isopropyl acid phosphate, 66.5 parts of kaolin and 30
parts of talc are well mixed while being powdered to obtain a dust.
FORMULATION EXAMPLE 6
Twenty parts of Compound No. 3 is mixed with 60 parts of an aqueous solution containing 3%
polyoxyethylene sorbitan monolactate and grained until the particle size of the active ingredient
becomes less than 3 microns. Twenty parts of an aqueous solution containing 3% of sodium alginate as
a dispersing agent is incorporated therein to obtain a suspension.
The dosage rate of the organic phosphorus compounds (I) may vary on the kind of preparation, sorts of
weeds or crop plants, the weather condition, etc. Generally, however, the dosage rate may be from 0.5
to 100 grams, preferably from 1 to 50 grams, of the active ingredient per are.
The application of the organic phosphorus compounds (I) as herbicides will be illustratively shown in
the following Examples wherein the herbicidal activity on weeds were evaluated as follows: the aerial
parts of the test plants were cut off and weighed (fresh weight); the percentage of the fresh weight of
the treated plant to that of the untreated plant was calculated with the latter fresh weight taken as 100;
and the phytotoxicity to crop plants and the herbicidal activity on weeds were evaluated by the standard
given in the table below. The rating values of phytotoxicity, 0 and 1, and those of herbicidal activity, 5
and 4, are generally regarded as satisfactory to protect crop plants and control weeds, respectively. The
rating values in the paddy field test alone were calculated from the dry weight of the test plants.

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to new phosphonic acid ester derivatives and, more particularly, to new
phenylthionophoshonic acid O,O-di-esters having a high insecticidal activity, high miticidal activity
and high nematocidal activity in combination. This invention also relates to a process for the
production of these new phosphonic acid ester derivatives, as well as to an insecticidal, miticidal and
nematocidal composition containing the above-mentioned new compound as active ingredient.
2. Description of the Prior Art
Many kinds of organo-phosphorus compounds having insecticidal activity, miticidal activity and/or
nematocidal activity are known. Thus, O-(N-alkoxy-benzimidoyl)-(thiono)phosphoric(phosphonic)acid esters having insecticidal and miticidal activities are disclosed in Japanese
patent application prepublication "Kokai" No. Sho 47-9149 (corresponding to U.S. Pat. No. 3,760,041),
Japanese patent application prepublication "Kokai" No. Sho 49-13335 (corresponding to U.S. Pat. No.
244/612
3,872,185) and Japanese patent application prepublications "Kokai" No. Sho 49-132244 and No. Sho
50-64436. O-(N-Alkoxy-substituted alkylimidoyl)-(thiono)phsphoric acid esters are also known to
have insecticidal and miticidal activities as disclosed in Japanese patent application prepublications
"Kokai" No. Sho 50-6724 and No. Sho 52-33627.
Amongst the insect pests, rice stem borer, brown planthoppers, rice leafhoppers, common cutworms
and aphids may be mentioned as the main insect pests which are predominantly infesting aquatic rice
plants cultivated in the submerged field or the crops cultivated in upland fields in recent years. For the
purpose of combating these main insect pests, there have been applied large quantities of insecticides
of the organo-phosphorus compound type, insecticides of the carbamate compound type, insecticides of
the chlorinated compound type and others since a long time ago. In these years, there occurs an
objectionable phenomena that the main insect pests have gained a resistance against the known
insecticidal compounds which have extensively been used in the crop fields.
SUMMARY OF THE INVENTION
An object of this invention is to provide a new insecticide of organophosphorus compound type to
which the resistance is not yet gained by the main insect pests of the crop fields. Another object of this
invention is to provide a new insecticide of organophosphorus compound type which exhibits a higher
insecticidal activity than that of the organophosphorus insecticides conventionally used in the crop
fields. Further objects of this invention will be clear from the following descriptions.
We, the present inventors, have synthetized a number of new organophosphonic acid esters and studied
their physiological properties. As a result, we have now found that amongst the new organophosphonic
acid esters, phenylthionophosphonic acid O,O-di-esters of the general formula: ##STR2## wherein R1
is a lower alkyl group; R2 is a hydrogen atom, a lower alkyl group or an unsaturated lower alkyl group;
and R3 is a lower alkyl group or an unsaturated lower alkyl group exhibit a high insecticidal activity, a
high miticidal activity and a high nematocidal activity in combination, and that the new compounds of
formula (I) show a remarkably high insecticidal activity against the "resistant" strains of insect pests
such as green rice leafhopper which have developed the resistance to various kinds of the known
organophosphorus type insecticides and of the known carbamate type insecticides.
According to a first aspect of this invention, therefore, there are provided as new compounds
phenylthionophosphonic acid O,O-di-esters of the general formula: ##STR3## wherein R1 denotes a
lower alkyl group; R2 denotes a hydrogen atom, a lower alkyl group or an unsaturated lower alkyl
group; and R3 denotes a lower alkyl group or an unsaturated lower alkyl group. The term "an
unsaturated lower alkyl group" means inclusively "a lower alkenyl group" and "a lower alkynyl group".
The term "lower" means that the concerned group contains 1 to 6 carbon atoms and preferably contains
1 to 4 carbon atoms.
DETAILED DESCRIPTION OF THE INVENTION
According to a specific embodiment of the first aspect of this invention, therefore, there are provided
new compounds of the general formula: ##STR4## wherein R4 is an alkyl group containing 1-6 carbon
atoms, R5 is a hydrogen atom, an alkyl group containing 1-6 carbon atoms, an alkenyl group
containing 2-6 carbon atoms or an alkynyl group containing 2-6 carbon atoms, and R6 is an alkyl group
containing 1-6 carbon atoms, an alkenyl group containing 2-6 carbon atoms or an alkynyl group
containing 2-6 carbon atoms.
More specifically, in formula (I'), R4 is methyl or ethyl group; R5 is hydrogen, methyl, ethyl, n-propyl,
i-propyl, n-butyl, vinyl, propenyl or ethynyl group; and R6 is methyl, ethyl, i-propyl, vinyl, allyl or
propargyl group.
According to a preferred embodiment of the first aspect invention, there are provided as new
compounds phenylthionophosphonic acid O,O-di-esters of the formula: ##STR5## wherein R7 is an
alkyl group of 1-4 carbon atoms, an alkenyl group of 2-4 carbon atoms or an alkynyl group of 2-4
carbon atoms.
More specifically, in formula (I"), R7 is methyl, ethyl, i-propyl, allyl or propargyl group.
245/612
Although the new compounds of general formula (I), (I') or (I") according to this invention have a
chemical structure similar to that of the known O-(N-alkoxy-benzimidoyl)-(thiono)phosphoric(phosphonic)acid esters and O-(N-alkoxy-substituted alkylimidoyl)-(thiono)phosphoric acid
esters taught in the chemical literature above-referred to, it has been found that the new compounds of
this invention are remarkably superior to the known, similar compounds in the insecticidal activity,
miticidal activity and nematocidal activity. Besides, it is observed that the pesticidal activities of the
new compounds of this invention are much more rapid and lasting than those of the known, similar
compounds and are systemic in nature which makes it possible to achieve the desired pesticidal effect
on pests inhabiting on the earth by applying the compounds to aquatic surface or soil. In addition, the
new compounds of this invention advantageously exhibit little or no toxicity to mammalian animals
and do not exhibit any phyto-toxicity to crop plants at all.

emulsification, dispersion, solubilization, wetting, foaming, lubrication and/or spreading. Surface
active agents may be of nonionic, anionic, cationic and amphoteric types. Examples of the nonionic
type are polyoxyethylene alkylethers, polyoxyethylene alkylesters, polyoxyethylene
sorbitanalkylesters, sorbitan alkylesters and the like. Examples of the anionic type are alkylbenzene
sulfonates, alkylsulfosuccinates, alkyl sulfates, polyoxyethylene alkylsulfates, aryl sulfonates and the
like. Examples of the cationic type include quaternary ammonium compounds such as stearyl trimethyl
ammonium chloride and alkyl dimethylbenzyl ammonium chloride and polyoxyethylene alkylamines.
Examples of the amphoteric type are carboxylic acids of betaine type and alkyl sulfates.
Other additives which may be used as an adjuvant include polyvinyl alcohol, carboxymethylcellulose,
acasia gum, polyvinyl acetate, gelatin, casein, sodium alginate and tragacanth gum, for example.
The composition according to this invention in the form of a variety of formulations as abovementioned may contain 0.1 to 95%, preferably 0.5 to 90%, by weight, of a phenylthionophosphonic
acid O-alkyl,O-(N-alkoxyalkanoylimidoyl)ester of formula (I) according to this invention. Thus, the
composition may usually contain 0.1 to 5% by weight of the active compound when formulated in the
form of dusting powder, DL powder or fine granules, 1 to 10% by weight in the form of granules and 5

EXAMPLE 10
This Example illustrates the test of estimating the effect of the test compounds for controlling
"resistant" strains of green rice leafhopper.
Aquatic rice plants of an average height of about 40 cm were planted in a pot of square cross-section (6
cm.times.6 cm) and made of black colored polyvinyl chloride. These aquatic rice plants were treated by
dusting thereon the dusting powder of this invention made in the Example 6, at the rate of application
of the active compound as indicated in Table 4 below. After the dusting treatment, the treated rice
254/612
plants were covered with a cylindrical box of 11 cm diameter in the cross-section and made of
polyvinyl chloride. Twenty adult female green rice leafhoppers (Nephotettix cincticeps) of 3 days old
after the emergence of such "resistant" strain which showed the resistance against the known organophosphorus type insecticides and against the known carbamate-type insecticides were released into and
confined in the cylindrical box containing the treated aquatic rice plants. The rice plants-cultivating
pot, together with the covering cylindrical box of polyvinyl chloride, was kept in a constanttemperature room at 25 DEG C. 48 Hours after the releasing of the insects, percent of the mortality was
assessed. The tests were conducted with three replicates for a particular value of the concentration of
the active compound under test, and the average of % mortality was calculated. The results (expressed
as averaged % mortality) are set out in Table 4 below.

EXAMPLE 13
This Example illustrates the test of estimating the effect of the new compounds for controlling twospotted spider mite.
Kidney-bean plants at the single true-leaf-extending stage planted in a pot of square cross-section (6
cm.times.6 cm) were infested with adult female two-spotted spider mites (Tetranychus urticae) which
were reared over some successive generations. The number of the mites infested was 20 per pot. The
258/612
infesting mites were allowed to produce the eggs on the bean plants. 24 Hours after the infestation, the
bean plants and the mites were sprayed with 30 ml/pot of the composition under test which was
prepared by diluting with water the wettable powder of this invention made in the Example 5 to a
concentration of the active compound as indicated in Table 7 below. The treated plants in the pot were
kept in a constant-temperature room at 25 DEG C. 3 Days after the spraying, the numbers of dead
mites and surviving mites were counted and the percent mortality was assessed in the same manner as
in Example 10. The tests were conducted with three replicates for a particular value of the
concentration of the active compound under test, and the average of mortality (%) was calculated. The
results (expressed as the averaged % mortality) are given in Table 7 below.

EXAMPLE 14
This Example illustrates the test under submerged condition of estimating the effect of the test
compounds for controlling small brown planthopper.
Aquatic rice plants were transplanted and cultivated under the submerged condition in a pot having an
area of 1/10,000 ares at the soil surface. When the aquatic rice plants so cultivated reached a 4-leave
stage, the granules of this invention prepared in the Example 7 were scattered onto the surface of the
submerging water where the pot was immersed. The granules were applied at the rate of application of
the active compound as indicated in Table 8 below. The test plots were classified into two, the first plot
was such that two days lapsed between the application of the granules and the release of the insect
pests under test; and the second plot was such that 5 days lapsed between the application of the
granules and the release of the insect pests. The predetermined 2 or 5 days later, the pot was covered
with a cylindrical box made of a plastic resin material and having 10 cm diameter and 30 cm height.
Into the box covering the pot were released and confined therein 20 adult small brown planthoppers
(Laodelphax striattellus). 48 Hours after the release of the planthoppers, the number of the dead insects
was counted and % mortality was assessed. The tests were conducted with three replicates for a
particular value of the concentration of the active compound under test, and the average of % mortality
was calculated. The results (expressed as the averaged % mortality) are set out in Table 8 below.

EXAMPLE 15
This Example illustrates the test of estimating the effect of test compounds for controlling southern
root-knot nematode.
A quantity of soil infested by southern root-knot nematode (Meloidogyne incognita) was admixed with
a predetermined amount of the granules of this invention prepared in the Example 7 to such
concentration of the active compound as indicated in Table 9. The mixture of the soil and the granules
was stirred and mixed uniformly and then charged into a pot having an area of 1/5,000 ares. In the
treated soil charged in the pot were sown 20 seeds of tomato plant per pot. The tomato seeds were
cultivated in a greenhouse. 4 Weeks after the seed sowing, the grown roots of the young tomato plant
were withdrawn from the soil without damaging the roots, and the degree of injury of the roots was
evaluated according to the following ratings to estimate the root-knot index:
Ratings of root-knot (Degree of injury):
0--No root-knot formation (perfect control).
1--Slight root-knot formation was observed at the tip of small side-roots.
2--Root-knot formation was observed in the small side-roots but the knots formed were not yet
connected with each other.
3--Root-knot formation was observed along the whole length of the small side-roots with some knots
being connected with each other.
4--Root-knot formation was observed in the main root, too, with the many knots in the side-roots being
connected with each other.
5--The number of root-knots formed were very much great, with the knots connected with each other in
the main root and also in the side-roots (corresponding to the "control" plot where no treatment was
made).
Root-knot index was estimated according to the following equation: ##EQU1##
The tests were conducted with three replicates for a particular value of the concentration of the active
compound under test, and the average of the estimated root-knot indexes was calculated. The results
(expressed as the averaged % root-knot index) are listed in Table 9 below.

The phenylpyrimidines of the formula I are most suitable for protecting cultivated plants such as
sorghum, rice, maize, cereals (wheat, rye, barley, oats), cotton, sugar beet, sugar cane, soybeans etc.,
from attack by aggressive agrochemicals, especially by herbicides belonging to a wide variety of
compound classes, e.g. triazines, phenylurea derivatives, carbamates, thiocarbamates, haloacetanilides,
halophenoxyacetates, substituted phenoxyphenoxyacetates and -propionates, substituted
pyridyloxyphenoxyacetates and -propionates, benzoic acid derivatives etc., where these compounds do
not have a selective action or do not act selectively enough, i.e. where they also damage the cultivated
plants to a greater or lesser extent in addition to the weeds to be controlled. The invention also relates
to compositions which contain these phenylpyrimidines of the formula I, together with herbicides.
Particularly suitable antidotes are the phenylpyrimidines of the formula I, wherein n is an integer of
from 1 to 5, R is hydrogen, halogen, cyano, nitro, hydroxyl, C1 -C6 alkyl, C1 -C6 alkoxy, C1 -C6

alkoxy; R1 and R3 are halogen and R2 is hydrogen, especially

2-(4-hydroxyphenyl)-4,6-dichloropyrimidine,
2-(3-nitrophenyl)-4,6-dichloropyrimidine and
2-(3-chloro-4-fluorophenyl)-4,6-dichloropyrimidine.
Various compounds which are able to antagonise specifically the harmful effects of a herbicide on
cultivated plants have already been proposed as safeners or antidotes, i.e. compounds which protect
cultivated plants without noticeably influencing the herbicidal action on the weeds which it is desired
to control. Depending on their properties, such antidotes, also known as safeners, can be used for
pretreating the seeds of the cultivated plants (dressing seeds or seedlings) or before sowing seeds in
furrows, or as tank mixture together with the herbicide, before or after emergence of the plants.
For example, British patent specification No. 1,277,557 discloses the treatment of seed and seedlings of
wheat and sorghum with certain esters and amides of oxamic acid from attack by N-methoxymethyl2',6'-diethyl-chloroacetanilide (Alachlor). Other publications (German Offenlegungsschrift
specification Nos. 1 952 910 and 2 245 471, and French patent specification No. 2 021 611), propose
268/612
antidotes for the treatment of cereals, maize seeds and rice seeds to protect them from attack by
herbicidal thiocarbamates. In German patent specification No. 1 576 676 and U.S. Pat. No. 3,131,509,
hydroxyaminoacetanilides and hydantoins are suggested for protecting cereal seeds against carbamates
such as IPC, CIPC, etc. Further development, however, has shown all these preparations to be
unsatisfactory.
Surprisingly, phenylpyrimidines of the formula I have the property of protecting cultivated plants from
attack by aggressive agrochemicals, in particular from herbicides belonging to a wide range of
compound classes, for example chloroacetanilides, chloroacetamides, carbamates and thiocarbamates,
diphenyl ethers and nitrodiphenyl ethers, benzoic acid derivatives, triazines and triazinones,
phenylureas, nitroanilines, oxdiazolones, pyridyloxyphenoxy derivatives, phosphates and pyrazoles,
where these compounds are not tolerated or are insufficiently tolerated by the cultivated plants.
The phenylpyrimidines of this invention preferably protect herbicides belonging to the classes of the
chloroacetanilides, chloroacetamides, thiocarbamates, and phosphates.
Depending on the particular purpose, a safener or antidote of the formula I can be used for pretreating
the seeds of the cultivated plant or incorporated in the soil before or after sowing, or else applied by
itself alone or together with the herbicide before or after emergence of the plants. In principle,
therefore, the treatment of the plant or seeds can be carried out independently of the time of application
of the phytotoxic chemical. However, the treatment can also be carried out simultaneously (tank
mixture). Preemergence treatment includes both the treatment of the crop area before sowing
(ppi=preplant incorporation), and the treatment of the sown crop areas in which the plants have not yet
emerged.
The rates of application in which the antidote is employed in relation to the herbicide depend largely on
the mode of application. Where a field treatment is carried out, either as tank mixture or if herbicide
and antidote are applied separately, the ratio of antidote to herbicide is usually from 1:100 to 10:1, with
the preferred range however being from 1:5 to 8:1, most preferably 1:1.
When dressing seeds and taking similar protective measures, however, much smaller amounts of
antidote are required in comparison e.g. with the amounts of herbicide employed later per hectare of
crop area. For seed dressing, 0.1 to 10 g of antidote is usually required per kg of seeds, with the
preferred amount being from 1 to 2 g. If the antidote is to be applied shortly before sowing by seed
soaking, then e.g. antidote solutions which contain the active ingredient in a concentration of 1-10000
ppm, preferably 100-1000 ppm, are used.
Protective measures such as seed dressing with an antidote of the formula I and a possible later field
treatment with agrochemicals, normally follow at a greater interval of time. Pretreated seeds and plants
can come into contact later with different chemicals in agriculture, horticulture and forestry.
Accordingly, the invention also relates to plant protection compositions which contain, as active
ingredient, an antidote of the formula I together with conventional carriers. If appropriate or desired,
such compositions can additionally be mixed with the chemical against the action of which it is desired
to protect the cultivated plant, for example with a herbicide.
Cultivated plants within the scope of this invention are all plants which, in any form, can be harvested
(seeds, roots, stalks, tubers, leaves, blossoms) and from which extracts can be obtained (oils, sugar,
starch, protein) and which for this purpose are cultivated and tended. To these plants belong e.g. all
species of cereals such as wheat, rye, barley and oats, and also in particular rice, sorghum, cotton, sugar
beet, sugar cane, soybeans, beans and peas.
The antidote will be employed whereever it is intended to protect a cultivated plant from the
phytotoxicity of a chemical.

The phenylpyrimidines of the formula I which act as antidotes may optionally be employed after
application of the agrochemical or also simultaneously with it.
Many phenylpyrimidines of this invention are novel, whilst others are known compounds.
Phenylpyrimidines are used as intermediates in the manufacture of dyes, in which connection attention
is drawn to e.g. British patent specification No. 1,502,912 or to published European patent application
Nos. 20 298 and 31 796. They are also known as intermediates of pharmacologically active
270/612
compounds, q.v. J. Med. Chem. 1978 (21), pp. 123-126, or they are met with elsewhere in the chemical
literature, q.v. Bull. Soc. Chem. Jap. 44 (8), pp. 2182-5.
The phenylpyrimidines of the formula I can be obtained by known synthesis routes. The 2phenylpyrimidine ring is formed e.g. by condensation of a phenylamidine with a malonic acid
derivative.
The 2-phenylpyrimidines are obtained by condensing a phenylamidine with adialkyl malonate in
alcoholic solution in the presence of a base ##STR3## and then, if desired, replacing the hydroxyl
groups of the resultant 2-phenyl-4,6-dihydroxypyrimidine of the formula IV by halogen atoms with a
halogenating agent (phosphoroxy chloride, phosphoroxy bromide, sulfuryl chloride, bromosuccinimide
etc.) and, if desired, replacing these halogen atoms in turn by further radicals R1 and R3.
If R2 is hydrogen, this can be replaced e.g. by treatment with chlorine or bromine in a polar solvent,
e.g. glacial acetic acid.
The halogen atoms in the positions 4, 5, and 6 of the pyrimidine ring can in turn be replaced, in known
manner, by alcohols, mercaptans or amines.
The following publications, for example, are cited as references: J. Chem. Soc. 1965, pp. 5467-5473, J.
prakt. Chem. 312 (1970), pp. 494-506, J. Chem. Soc. Perkin Trans.1 1977, pp. 2285-6.
Phenylpyrimidines in which R1 is an alkyl or phenyl group are obtained e.g. by condensation of a
phenylamidine with an alkyl ester of an acetoacetic acid: ##STR4## Here too the --OH group can be
replaced in known manner by a halogen atom, which in turn can be replaced by an alcohol, a thiol or an
amine.
It is also possible to prepare e.g. 2-phenyl-4,6-dichloropyrimidine and 2-phenyl-4-chloro-6hydroxypyrimidines by reaction of chlorobenzylidine-carbamoyl chlorides with an aliphatic nitrile in
the presence of hydrogen chloride: ##STR5## q.v. Bull. Soc. Chem. Japan 44 (1971), pp. 2182-2185.
2-Phenyl-4,6-dichloropyrimidine can be obtained e.g. in accordance with Ang. Chemie 89 (1977), pp.
816-817, e.g. by condensation of a N-phenyl cyanamide and a N,N-dialkyl amide in POCl3 at 100
DEG C.: ##STR6##
In the above formulae, R, R2 and n are as defined for formula I.
The synthesis of such compounds or the exchange of radicals R1, R2 and R3 by other substituents cited
in the definition are procedures which are known per se. As regards the preparation of these
compounds attention is drawn to the Examples or to the literature. A further reference is also "The
Chemistry of Heterocyclic Compounds", 16, Interscience Publishers, New York 1962, pp. 119 ff.
The compounds of formula I can be used by themselves alone or together with the compounds which it
is desired to antagonise.
The compounds of the formula I are used in unmodified form or preferably together with the adjuvants
conventionally employed in the art of formulation, and are therefore formulated in known manner to
emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders,
soluble powders, dusts, granulates, and also encapsulations in e.g. polmyer substances. Just like the
nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering
or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.
The formulations, i.e. the compositions or preparations containing the compound (active ingredient) of
the formula I and, where appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g. by
homogeneously mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid
carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms,
e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl
271/612
phthalate, aliphatic hydrocarbons such as cyclohexane, or paraffins, alcohols and glycols and their
ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether;
ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl
sulfoxide or dimethyl formamide; as well as epoxidised vegetable oils such as epoxidised coconut oil
or soybean oil; or water.
The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such
as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it
is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable
granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or
bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. In addition, a great
number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite
or pulverised plant residues.
Depending on the nature of the compound of formula I to be formulated, suitable surface-active
compounds are nonionic, cationic and/or anionic surfactants having good emulsifying, dispersing and
wetting properties. The term "surfactants" will also be understood as comprising mixtures of
surfactants.
Suitable anionic surfactants can be both water-soluble soaps and water-soluble synthetic surface-active
compounds.
Suitable soaps are the alkali, alkaline earth or unsubstituted or substituted ammonium salts of higher
fatty acids (C10 -C22), e.g. the sodium or potassium salts of oleic or stearic acid, or of natural fatty
acid mixtures which can be obtained e.g. from coconut oil or tallow oil. Mention may also be made of
fatty acid methyltaurin salts.
More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty
sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or sulfates are usually in the form of alkali, alkaline earth or unsubstituted or
substituted ammonium salts and contain a C8 -C22 alkyl radical which also includes the alkyl moiety
of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecylsulfate or of a mixture
of fatty alcohol sulfates obtained from natural fatty acids. These compounds also comprise the salts of
sulfuric acid esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated
benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical
containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or
triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a
naphthalenesulfonic acid/formaldehyde condensation product. Also suitable are corresponding
phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of
ethylene oxide.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols,
or saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether
groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the
alkyl moiety of the alkylphenols.
Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with
polypropylene glycol, ethylenediaminepolypropylene glycol and alkylpolypropylene glycol containing
1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups
and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 glycol units per
propylene glycol unit.
Representative examples of non-ionic surfactants are nonylphenol-polyethoxyethanols, castor oil
polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol,
polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acids esters of polyoxyethylene
sorbitan and polyoxyethylene sorbitan trioleate are also suitable non-ionic surfactants.
272/612
Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least
one polyglycol ether or C8 -C22 alkyl radical and, as further substituents, lower unsubstituted or
halogenated alkyl, benzyl or lower hydroxyalkyl radicals. The salts are preferably in the form of
halides, methylsulfates or ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2chloroethyl)ethylammonium bromide.
The surfactants customarily employed in the art of formulation are described e.g. in the following
publications: "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ringwood,
N.J., 1979; Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co. Inc.,
New York, 1964.
The pesticidal formulations will normally contain 0.1 to 99%, preferably 0.1 to 95%, of a compound of
the formula I, 1 to 99% of a solid or liquid adjuvant, and 0 to 25%, preferably 0.1 to 25%, of a
surfactant. Whereas commercial products will be preferably formulated as concentrates, the end user
will normally employ dilute formulations.
The compositions can also contain further ingredients such as stabilisers, antifoams, viscosity
regulators, binders, adhesives, as well as fertilisers or other active compounds, in order to attain special
effects.
In the following Examples parts and percentages are by weight.
Preparatory Examples

4,6-dichloro-2-p-tolylpyrimidine at 60 DEG-65 DEG C. over 15 minutes. The mixture is then heated to
the boil and refluxed for a further 4 hours to bring the reaction to completion. Excess isopropanol is
then distilled off and the residual oil is taken up in chloroform. The chloroform layer is washed with
water, dried over sodium sulfate, and filtered. The solvent is then distilled off, affording 112 g of 2-ptolyl-4,6-bis-isopropoxypyrimidine in the form of a yellowish oil which is purified by high vacuum
distillation. The boiling point is 123 DEG C./5.332 Pascal.
The starting 2-p-tolyl-4,6-dichloropyrimidine is prepared as follows:
(b) 102.3 g of p-tolylamidine hydrochloride and 99.3 g of diethyl malonate are suspended in 520 ml of
anhydrous ethanol. With good stirring and cooling, 323.7 g of a 30% solution of sodium methylate are
then run in. The reaction mixture is then heated to reflux and stirred at reflux temperature for 5 hours.
The solvent is then distilled off and the residue is taken up in 1000 ml of water, heated to 80 DEG C.,
and the somewhat turbid solution is then filtered over silica gel. The filtrate is cooled and acidified with
15% hydrochloric acid. The dense crystalline slurry is filtered and the filter residue is washed with

chloride was heated to the boil and the mixture is stirred at reflux for 1 hour. Excess phosphoroxy
chloride is distilled off and then the residue is washed with iced water to remove any phosphoroxy
chloride still remaining, triturated with iced water, and filtered. The filter residue is washed with iced
water and vacuum dried at 40 DEG-50 DEG C., affording 85.9 g of 2-p-tolyl-4,6-dichloropyrimidine

111.7 g of 4,6-diisopropoxy-2-p-tolylpyrimidine and 450 ml of carbon tetrachloride are heated to 70
DEG-75 DEG C. To the resultant solution is added 0.5 g of dibenzoyl peroxide, followed by the
addition, over 45 minutes, of a mixture of 1 g of azoisobutyronitrile and 70.8 g of Nbromosuccinimide. The mixture is refluxed for 2 hours to bring the reaction to completion. The
precipitated succinimide is then filtered off and excess carbon tetrachloride is removed by distillation,
affording 141 g of the title compound with a melting point of 74 DEG-75 DEG C. after purification
with methanol.
Example 3

solution are then added, over 10 minutes and with gentle cooling, 95.64 g of 2-p-tolyl-4,6dichloropyrimidine. The mixture is then heated to reflux and kept at the boil for 4 hours. The solvent is
removed by distillation and the residue is charged into 1000 ml of water. The product is triturated with
water to remove sodium chloride, isolated by filtration, washed with water and dried in the air,
affording 90.4 g of the title compound with a melting point of 61 DEG-62 DEG C.

38.2 g of 4-chlorobenzylamidine hydrochloride and 33.6 g of diethyl malonate in 175 ml of methanol,
and the mixture is subsequently refluxed for 5 hours. The solvent is then distilled off in a rotary
evaporator and the residue is taken up in 1000 ml of hot water and the solution is filtered. The filtrate is

methylene chloride and the solution is treated with fuller's earth, dried and concentrated. The residue
crystallises, giving 16.2 g of 2-p-chlorophenyl-4,6-dichloropyrimidine with a melting point of 119
DEG-120 DEG C. A sample sublimed at 80 DEG/0.02 mbar melts at 120 DEG-121 DEG C.
Example 6
2-p-Methoxyphenyl-4,6-dihydroxypyrimidine ##STR12##
338 g of a 30% solution of sodium methylate in methanol are added over 10 minutes to a suspension of
112 g of p-methoxybenzamidine hydrochloride and 101 g of diethyl malonate in 520 ml of ethanol, and
the mixture is subsequently refluxed for 5 hours. The reaction mixture is then concentrated by rotary
evaporation and the residue is dissolved in 1000 ml of warm water of 80 DEG C. The solution is
filtered and the filtrate is acidified to pH 1. The precipitate is isolated by filtration and vacuum dried at
80 DEG C., affording 109.8 g of 2-p-methoxyphenyl-4,6-dihydroxypyrimidine with a melting point of
318 DEG C. (decompos.).
Example 7
2-p-Methoxyphenyl-4,6-dichloropyrimidine ##STR13##
274/612
126 ml of phosphoroxy chloride (POCl3) and then 57 ml of N,N-dimethyl aniline are added dropwise
over 30 minutes to 54.5 g of 2-p-methoxyphenyl-4,6-dihydroxypyrimidine with cooling, such that the
temperature does not exceed 45 DEG C. The reaction mixture is then stirred for 2 hours at room
temperature and subsequently refluxed for 2 hours. The reaction mixture is then concentrated by rotary
evaporation and the residue is triturated in 2 liters of iced water. The solid product is isolated by
filtration, dissolved in 1.5 liters of methylene chloride and the solution is treated with fuller's earth and
dried. The methylene chloride solution is filtered and concentrated. The residue is recrystallised from
ethanol, affording 51 g of crystalline 2p-methoxyphenyl-4,6-dichloropyrimidine with a melting point of
127 DEG-128 DEG C.

FORMULATION EXAMPLES
The compounds of formula I will normally not be used by themselves in agriculture. They are used in
the form of ready-for-use formulations which can be applied either direct or diluted with water.
EXAMPLE 8
Dusts: The following substances are used to formulate (a) a 5% and (b) a 2% dust:
>;tb;______________________________________
>;tb;(a) 5 parts of 2-p-tolyl-4,6-bis-isopropoxypyrimidine
>;tb;
or of a mixture thereof with 2-chloro-2',6'>;tb;
diethyl-N--(butoxymethyl)-acetanilide
>;tb;
95 parts of talcum;
>;tb;(b) 2 parts of the above active ingredient or a mixture
>;tb;
1 part of highly dispersed silicic acid
>;tb;
97 parts of talc;
>;tb;______________________________________
The active ingredients are mixed with the carriers and ground and in this form can be processed to
dusts for application.
Example 9
Granulate: The following substances are used to formulate a 5% granulate:
>;tb;______________________________________
>;tb;5
parts of 2-p-tolyl-4,6-isopropoxy-5-bromopyrimidine
>;tb;
or of a mixture thereof with 2-chloro-2',6'-diethyl>;tb;
N--(methoxymethyl)-acetanilide
>;tb;0.25 part of epoxidised vegetable oil
300/612
>;tb;0.25 part of cetyl polyglycol ether
>;tb;3.25 parts of polyethylene glycol
>;tb;91 parts of kaolin (particle size 0.3-0.8 mm).
>;tb;______________________________________
The active ingredient or mixture is mixed with the vegetable oil and the mixture is dissolved in 6 parts
of acetone. Then polyethylene glycol and cetyl polyglycol ether are added. The resultant solution is
sprayed on kaolin and the acetone is evaporated in vacuo. A microgranular formulation of this kind can
be conveniently incorporated in seed furrows.
Example 10
Wettable powders: The following constituents are used to formulate (a) a 70%, (b) a 40%, (c) and (d) a
25% and (e) a 10% wettable powder:
>;tb;______________________________________
>;tb;(a) 70 parts of 2-p-tolyl-4,6-bis-(methoxyethyl)-5-chloro>;tb;
pyrimidine or a mixture thereof with 2-chloro>;tb;

BIOLOGICAL EXAMPLES
The ability of the compounds of formula I to protect cultivated plants from the phytotoxic effects of
potent herbicides can be seen from the following Examples. In the test procedures, the compounds of
formula I are designated as antidotes. The protective action is indicated in percent. 0% denotes the
action of the herbicide when applied by itself; 100% denotes the desired normal growth of the
cultivated plant. A protective action of at least 10% is significant.
Example 13
Tests with antidote and herbicide in transplanted rice. Method of application: tank mixture
302/612
Rice plants are reared in soil to the 11/2- to 2-leaf stage. The plants are then transplanted in bunches
(always 3 plants together) in sandy loam in containers measuring 47 cm.times.29 cm.times.24 cm. The
surface of the soil is then covered with water to a height of 1.5 to 2 cm. Two to three days after
transplantation, the herbicide and the antidote as test substance are applied together direct to the water
as tank mixture. The protective action of the antidote is evaluated in percent 24 days after
transplantation. The plants treated with herbicide alone (no protective action) as well as the completely
untreated controls (100% growth) serve as references for the evaluation. The results are reported
below.

The antidote, compound 1, as well as other 2-phenylpyrimidines of this invention, were also able to
protect rice from the phytotoxic effects of S-4-benzyl-diethylthiocarbamate and 5-tert-butyl-3-(2,4dichloro-5-dichloro-5-isopropoxyphenyl)-1,3,4-oxdiazol -2-one ("Oxidiazon").
Example 20
Test with antidote and herbicide with rice sown in water. Application of the antidote while soaking the
rice seeds.
Rice seeds are soaked for 48 hours in solutions of the test antidote at a concentration of 100 ppm. The
seeds are then allowed to dry for about 2 hours until they are no longer tacky. Plastic containers
measuring 25 cm.times.17 cm.times.12 cm are filled with sandy loam to 2 cm below the edge. The
soaked seeds are sown on the surface of the soil in the containers and then very lightly covered. The
soil is kept in a moist (non-marshy) state. Then a dilute solution of the herbicide is sprayed onto the
surface of the soil. The water level is raised gradually in accordance with the growth of the plants.
Evaluation of the protective action in percent is made 21 days later. The plants treated with herbicide
alone (no protective action) as well as the completely untreated controls (100% growth) serve as
references for the evaluation. The results are reported in the following table.

Example 21
312/612
Test with antidote and herbicide with rice sown in water. Application of antidote and herbicide in
nutrient solution.
Seeds which would normally be damaged in the test concentrations of the herbicide employed are sown
in granular zonolith (expanded vermiculite) in plastic flower pots (diameter 6 cm at the top) which are
perforated at the bottom. Each pot is then placed in a second transparent plastic flower pot (diameter 7
cm at the top) which contains about 50 ml of the nutrient solution prepared with herbicide and antidote.
This nutrient solution then rises by capillary action in the filling material of the smaller pot and
moistens the seed and the germinating plant. The loss in fluid is daily replenished to 50 ml with a
Hewitt nutrient solution. Evaluation of the protective action in percent is made 3 weeks after the start
of the test. The plants treated with herbicide alone (no protective action) as well as the completely
untreated controls (100% growth) serve as references for the evaluation. The results are as follows:

Example 22
Test with antidote and herbicide with rice sown dry (20 days after sowing, when the rice plants have
attained the 3-leaf stage, the soil is flooded). Application of antidote and herbicide as tank mixture.
Rice seeds of the IR-36 variety are sown in containers measuring 47 cm.times.29 cm.times.24 cm,
covered and gently pressed firm. The test antidote and the herbicide are then sprayed together as tank
mixture onto the soil. About 20 days after sowing, when the rice plants are attained the 3-leaf stage, the
surface of the soil is covered with water to a height of 4 cm. The protective action of the antidote is
evaluated in percent 30 days after transplantation. The plants treated with herbicide alone (no
protective action) as well as the completely untreated controls (100% growth) serve as references for
the evaluation. The results are reported in the following table.

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is directed to novel phenylhydrazine derivatives which exhibit activity as insecticides,
acaricides and nematicides. This invention is also directed to insecticidal, acaricidal or nematicidal
compositions comprising such compounds as well as to methods of controlling insects, acarids and
nematodes employing such compounds or compositions.
Destruction by insects, acarids and nematodes presents a serious problem to agriculture. A wide variety
of field crops are in need of protection from nematodes, acarids, and insects including such valuable
crops as soybeans, corn, peanuts, cotton, alfalfa, rice and tobacco. In addition, vegetables, such as
tomatoes, potatoes, sugarbeet, carrots, peas, and the like as well as fruits, nuts, ornamentals and seed
bed crops such as apples, peaches, almonds, citrus fruit and grapes may also require protection from the
ravages of such pests.
323/612
Consequently, the development of new, more effective pesticides including insecticides, acaricides and
nematicides represents an ongoing scientific activity. More particularly, the development of pesticides
which are effective as both ovicides and larvicides are of interest.

Further, when X includes a substituent having a phenyl ring (i.e., is phenyl, phenylalkoxy, phenoxy or
benzyl), the phenyl ring is optionally substituted with one or more of halogen, nitro, lower alkyl, lower
alkoxy, lower haloalkyl, or dialkylamino.
The instant invention further relates to pesticidal compositions comprising:
a) an effective amount of a compound having the structure of formula (I) or (II) above as an active
ingredient; and (b) an agriculturally acceptable carrier.
The present invention is also directed to a method for controlling pests such as insects, acarids or
nematodes which comprises applying an effective amount of a compound of formula (I) or (II) or of a
composition of the present invention to a locus to be protected or rid of pests.
DETAILED DESCRIPTION OF THE INVENTION
The compounds of the present invention have the structure (I) or (II) defined above. Preferred
compounds are those in which Y is hydrogen or COCF3.
The compounds having structure (I) may be prepared by reacting a substituted phenylhydrazine:
##STR3## with an acylating agent: ##STR4## wherein Z is halo or ##STR5## and an equivalent of an
HCl acceptor such as pyridine in a solvent such as toluene. The product of this reaction may be further
acylated, or converted by oxidation with an oxidizing agent such as Pd/air to form compounds having
structure (II).
The compositions of this invention comprise (a) a compound having a structure within that of formula
(I) or (II) above, and (b) a suitable carrier. Such suitable carriers may be solid or liquid in nature.
324/612
Suitable liquid carriers may be comprised of water, alcohols, ketones, phenols, toluene and xylenes. In
such formulations, additives conventionally employed in the art may be utilized such as, for example,
one or more surface active agents and/or inert diluents, to facilitate handling an application of the
resulting pesticide composition.
The pesticidal compositions may alternatively comprise solid carriers taking the form of dusts,
granules, wettable powders, pastes, aerosols, emulsions, emulsifiable concentrates, and water-soluble
solids.
For example, the pesticidal compounds of this invention may be applied as dusts when admixed with or
absorbed onto powdered solid carriers, such as mineral silicates, e.g., mica, talc, pyrophyllite and clays,
together with a surface-active dispersing agent so that a wettable powder is obtained which then is
applicable directly to the loci to be treated. Alternatively, the powdered solid carrier containing the
compound admixed therewith may be dispersed in water to form a suspension for application in such
form.
Granular formulations of the compounds, suitable for application by broadcasting, side dressing, soil
incorporation or seed treatment, are suitably prepared using a granular or pellitized form of carrier such
as granular clays, vermiculite, charcoal or corn cobs.
Alternatively, the pesticidal compounds may be applied in liquids or sprays when utilized in a liquid
carrier, such as in a solution comprising a compatible solvent such as acetone, benzene, toluene or
kerosene, or as dispersed in a suitable non-solvent medium, for example, water.
Another method of application to loci to be treated is aerosol treatment, for which the compound may
be dissolved in an aerosol carrier which is a liquid under pressure but which is a gas at ordinary
temperature (e.g., 20 DEG C.) and atmospheric pressure. Aerosol formulations may also be prepared
by first dissolving the compound in a less volatile solvent and then admixing the resulting solution with
a highly volatile liquid aerosol carrier.
For pesticidal treatment of plants (such term including plant parts), the compounds of the invention
preferably are applied in aqueous emulsions containing a surface-active dispersing agent which may be
non-ionic, cationic or anionic. Suitable surface-active agents include those known in the art, such as
those disclosed in U.S. Pat. No. 2,547,724 (columns 3 and 4). The compounds of the invention may be
mixed with such surface-active dispersing agents, with or without an organic solvent, as concentrates
for the subsequent addition of water to yield aqueous suspensions of the compounds at desired
concentration levels.
In addition, the compounds may be employed with carriers which themselves are pesticidally active,
such as insecticides, acaricides, fungicides or bactericides.
It will be understood that the amount of the pesticidally active compound in a given formulation will
depend upon the specific pest to be combatted, as well as upon the specific chemical composition and
formulation of the compound being employed, the method of applying the compound/formulation and
the locus of treatment so that the pesticidally effective amount of the compound may vary widely.
Generally, however, concentrations of the compound as the active ingredient in pesticidally effective
formulations may range from about 0.1 to about 95 percent by weight. Spray dilutions may be as low
as a few parts per million, while at the opposite extreme, full strength concentrates of the compound
may be usefully applied by ultra low volume techniques. Concentration per unit area, where plants
constitute the loci of treatment, may range between about 0.01 and about 50 pounds per acre, with
concentrations of between about 0.1 and about 10 pounds per acre preferably being employed for crops
such as corn, tobacco, rice and the like.
To combat pests, sprays of the compounds may be applied to the pests directly and/or to plants upon
which they feed or nest. The pesticidally active formulations may also be applied to the soil or other
medium in which the pests are present.
Harmful insects, nematodes and acarids attack a wide variety of plants, including both ornamental and
agricultural plants and inflict damage by consuming roots and/or foliage, withdrawing vital juices from
325/612
the plants, secreting toxins and often by transmitting
