chem lec 6 (sulfides, nitriles)

  • R-S-R

    functional group of sulfides

  • Sulfides

    it is also known as thioethers. The sulfur atom replaced the oxygen in ethers

  • -sulfide

    for common names of sulfides are made according to the two alkyl groups bonded to the functional group (-S-), written alphabetically followed by the word

  • -thia

    acyclic compound becomes complex, that is, when several sulfur atoms are present in a compound or in heterocyclic system, the word

  • sulfides

    are characterized by their strong odors, which are similar to thiol odor. This odor limits the applications of volatile thioethers.

  • volatile, higher melting point, lesss hydrophilic

    resemble ethers but sulfides have lesser characteristic of

  • polarizability of the divalent sulfur center

    why does ether have higher boiling point?

  • Thiphenes

    are used in making drugs and plasticizers, production of dye, synthetic resin, solvents, etc.

  • Sulfones

    are used principally for treatment of leprosy and it is also useful for the treatment of variety of dermatologic disorders such as dermatitis herpetiformis

  • Nitriles

    are compounds that contain a cyano (-CΞN) group.

  • Nitriles

    Considered to be carboxylic acid derivatives.

  • -nitrile

    • Acyclic nitriles are named by adding the suffix

  • number 1

    The carbon atom of the –CΞN group is assigned the

  • preffix -cyano

    When there are other functional group that take naming precedence over the nitrile/cyanide group, the

  • -carbonitrile

    Cyclic nitriles are named by adding the suffix

  • -onitrile

    Nitriles in which the -CN group can be thought of as having replaced the –COOH group of a corresponding carboxylic acid are named by removing the “ic acid” or “oic acid” and replacing it with

  • Liquid at room temperature

    • Low molecular weight nitriles are

  • electronegative nitrogen

    causes nitriles to be very polar molecules

  • chain length increases

    • Ethanenitrile is completely soluble in water, and the solubility then falls as

  • Nitrile rubber

    which is highly resistant to chemicals and is used to make protective gloves, hoses and seals.

  • Citalopram

    an antidepressant from Nitrile

  • Anastrozole

    for treating breast cancer from nitrile
