GENERAL DESCRIPTION & APPLICATIONS |
||
Nitrile is any
of a family of organic compounds containing cyano group (-C¡ÕN) which is attached
to a carbon atom and having the general formula RC¡ÕN. Their names are
corresponding to carboxylic acids by changing '-ic acid' to '-onitrile', or
'-nitrile', whichever preserves a single letter o. Examples are acetonitrile
from acetic acid and benzonitrile from benzoic acid. Pendant nitriles are often
named as ¡°cyano¡± substituents. Cyanoacetic acid, the half
nitriled-malonic acid, and its esters are basic chemical intermediates for
the production of;
Although nitriles don't have a carbonyl group, they are often considered as derivatives of carboxylic acids. Nitrile undergoes acid hydrolysis to form a carboxylic acid. Nitrile is reduced to form amine in the presence of nickel catalyst. Grignard reagents add to nitriles, forming a relatively stable imino derivative which can be hydrolyzed to a ketone. Metaloimine is hydrolyzed to give beta-ketoester. Nitrile undergoes a sequence of nucleophilic additions with an alcohol under acid catalysis, called nitrile alcoholysis. Nitriles are hydrolyzed to carboxylic acids, alcoholyzed to esters, reduced to amines, cyclyzed to pyridine derivatives. |
