5.2. The workshop sessions
Reactivity of carboxylic acids
Compounds in which one or more hydrogen atoms are replaced by carboxyl group
– СООН called carboxylic acids. Depending on the nature of organic radical RСООН carboxylic acids can be aliphatic, aromatic and heterocyclic. Carboxylic acids
on the number of carboxyl groups are divided into one main, two main and
polycarboxylic. For example, acetic СН3СООН and benzoic С6Н5СООН one main
acid, malon СООН - CH2 - СООН and terephthalic СООН- С6Н4 - СООН two main
acid. There are also saturated or unsaturated carboxylic acids.
Carboxylic acids are relatively high acidity.
Due to the-M-effect increases the mobility of hydrogen hydroxyl group. Due to
the separation of a proton from the hydroxyl group is formed high-stability
carboxylate - ion, communications and the charges in which aligned:
6
The reactionary centers of carboxylic acids and their derivatives
The reactions of nucleophilic substitution are characteristic of carboxylic acids
and their functional derivatives. In addition to electrofille the main and the weak CHacid centres available in aldehydes and ketons in a molecule of carbon acids and their
functional derivatives is also associated with carbon atom of carbonyl group deputy X
(potential leaving the group, nucleofuge), the ability to go in the form of anion X AC
or conjugate acid HX
.
At the expense +I-effect of negatively charged oxygen atom at carbon atom in the
product accession there is a partial negative chargeд which facilitates the separation
of the outgoing group X.
On the mechanism of the reaction proceeds in the presence of strong enough
nucleophile Y and the good of the outgoing group X. Easy nucleophilic attack
depends on the value of effective positive charge of the carbonyl group. In functional
derivatives of carboxylic acids R-CO-X it increases with the-I-effect of a deputy X
and decreases with increasing its +M-effect. Electrofile carbonyl carbon atom is
reduced by +M-effect of the functional deputy X associated with the carbon atom of
carbonyl group. For this reason, the nucleophilic reactions of derivatives of carboxylic
acids are often essential acid catalysis - protronation of the oxygen atom of carbonyl
group leads to the appearance of the full of positive charge at carbon atomа which
facilitates the attack nucleofille.
7
Factors influencing on reactivity of carboxylic acids.
The reactions of nucleophilic substitution of SN carboxylic acids and their
functional derivatives.
Getting halogen anhydrides
Halides are the most active acilic reagents among derivatives of carboxylic acids.
So, atsetilecholoride easily hydrolyses in water (atsetilate water) with heat release and
the formation of acetic acid. Halides RCOHal receive action (PCl5, PCl3) or
tionil chloride (SOCl2) on acid.
Getting anhydrides. When replacing the hydrogen hydroxyl group of carboxylic
acids on the balance of carboxylic acids are formed anhydrides acids. In practice
anhydrides are as follows:
8
Acetic acid
Anhydrides easily hydrolysable by with the formation of acids:
There are still mixed anhydrides consisting of residues of organic and mineral
acids. These include atsetilenitrate СН3СООNO2 and atsetilefosfate. Atsetilefosfate,
substituted atsetilfosfate and substituted atsilfosfate play an important role in
biochemical processes of the organism:
Atsetilfosfate
Substituted atsetilfosfate
Substituted atsilfosfate
(R - balance adenosine nucleoside, R’ radical carboxylic acid).
Substituted atsilfosfates are metabolites, with participation of which in the body is
the transfer of acil residuumes for hydroxyl, tionyl and аmino groups of various
compounds.
Esters and tioesters. Interaction of carboxylic acids from alcohols, leading to the
formation of esters, i.e. the reaction of the esterification is the most important process
of transformation of carboxylic acids and their functional derivatives.
The esterification reaction in the absence of catalysts is very slow due to the
already the low capacity of carbonyl groups in carboxylic acids to be subjected to
nucleophilic attack due to the +M- effect of OH group reduction and positive charge
at carbon atom. However, in the presence of mineral acids (sulfuric, HCl) reaction
considerably speeded up.
9
The process of esterification is reversible. Below is the mechanism of this reaction.
Complex esters RCOOR' and complex tioesters RCOSR' - the most widespread in
the nature as derivatives of carboxylic acids. Many medicines contain in their
composition of the ester group.
Hydrolysis. Esters may be subjected to hydrolysis (in contrast to the reaction of
the esterification) in both acidic and alkaline environments.
Hydrolysis in the alkaline environment is irreversible and requires ekvimoleculare
number of alkali.
The following scheme of the mechanism is fair to alkaline hydrolysis not only
esters, but also tioesters, halogen anhydrides, anhydrides and carboxylic acid amides.
The cause of the irreversibility of hydrolysis in the alkaline environment is the
formation of a stable masomer atsilate-ion.
The most common representative of these substances in the body is acetyl
coenzyme A (coenzyme of acetylation) – tioester of acetic acid and coenzyme A.
Atsetilecoenzyme A in vivo serves as a carrier of acetyl groups on nucleofile
substrates.
10
For example, with the participation of acetile coenzyme A precedes transformation
of choline in acetilcholine.
Atsetilecofermente A receives the following way:
Amides of carboxylic acids. At the substitution of hydroxyl group carboxylic
acid on aminogroup NH2 form amides of carboxylic acids:
Amides of carboxylic acids have a weakly acidic and weakly basic property.
Including of the electron acceptor acilic balance in the molecule of ammonia, leads to
the appearance of diluted acidic properties. Under the influence of +M-effect amides
are weakly basic properties compared with amines. The basic properties of amides
acids are evident in the reactions of formation of salts with stronger acids:
Amide group СN found in many biologically important
 
О Н
Substances, such as peptides and proteins.
Nitriles of carboxylic acids. Nitriles of carboxylic acids are obtained by
dehydration of acid amides:
As well as under the action of cyanide of alkaline metals on haloidalkils:
RBr  KCN  KBr  RC  N
Hydration nitriles pass in an alkaline environment. It can be imagined as
nucleophilic addition of water to a polarized triple connection nitrile with the
11
formation of the interim iminol, which are further changes in amide.
Nitriles represent more weak bases than amides. They are deprived of their basic
properties.When restoring nitriles into the corresponding amines:
R – C  N + 2H2  R – CH2 – NH2
One of the most important representatives of nitriles is acetonitrile CH3-С N.
Condensation reactions. Condensation reactions, which are based on the
ability of a carbonyl compounds to join the carbonyl group of the same or another
carbonyl compounds are typical not only for aldehydes and ketones, but also for the
derivatives of carboxylic acids in particular esters and tioefireов. Such reactions are
of great biological importance. With their help in the body leads to the formation of
new relations of the carbon-carbon. Indispensable participants of reactions by type
альдольного accession in vivo are tioesters of carboxylic acids - derivative
coenzyme A. In tioesters, compared with the usual esters due to the effective
positive charge on carbonil carbon atom nucleophilic substitution in the atom is
easier. For the same reason α - hydrogen atoms in tioesters more mobile and more
active in the reactions of condensation.
Biological importance of carbon acids.
Formic acid НСООН is contained in the nettles and in separations of the ants, it
is irritating to the skinу can cause burns. In medicine 1.25% alcohol solution of
formic acid is used in the treatment of rheumatism.
Acetic acid is a product of acetic fermentation of sugars. In medicine is applied in
the form of salts. Potassium acetate СН3СООК - moderate diuretic agent; lead acetate
(СН3СОО)2РЬ • ЗН20 - astringent, is used for inflammatory diseases of the skin and
mucous membranes. Acetic acid is used for food preservation.
Succinic acid has an unpleasant smell, is contained in gone bust oil and
perspiration.
Isovaleric acid is in the roots of valerian; a member of validol, valerian tincture.
Has a calming effect.
Sodium benzoate C6H5COONa - expectorant and poorly Dezin-фицирующее
means.A large medical-biological importance is the derivative of carbonic acid urethanes, ureid - and guanid derivatives.
12
Urethanes - esters of carbomide acid H2NCOOR - have psychic effect. Some of
them are used in nervous and mental diseases, showing sedative action. In particular,
meprotane (meprobamat) is used as a tranquilizer.

mechanism.
Activity
chlorangadrate is explained by the fact that chlorine is
the good of the leaving group. Positive mezomer effect of
chlorine less than the hydroxyl group, acidity more, and
the positive charge at carbon above and SN reaction is
easier.)
2. In the human body many reactions of carboxylic acids are held with the
participation of tioesters. For example, the transformation of choline in acetylcholine,
forming of citric acid from sorrelvinegar acid and atsetilecoenzyme A. Write the
reaction of transformation of choline in acetylcholine, explain the mechanism of
reaction and confirm why nature as a substrate or reagent chose tioesters, and not
esters of carboxylic acids. (Answer: the Reaction goes on SN mechanism. Activity
tioesters is explained by the fact that SR group is a well leaving the group. Positive
mezomer effect SR group less than the hydroxyl group, the radius of the sulphur
17
greater than the radius of oxygen, so the acidity more, and the positive charge at
carbon above and SN reaction is easier.)
3. In the body acilfosfate delivers acil group of alcohol, tiols and substances
containing aminogroupe. Write the reaction of the acetiladenilate and coenzyme A.
Explain the mechanism and why these substances exist in the form of phosphate
anhydride. (Answer: the reaction goes on SN macchanism.So as a phosphate group is
a well-outgoing group, anhydrate group easily hydrolyses and the gap anhydrate link
leads to the formation of a large amount of energy and increases the energy potential
of the process.)
