GENERAL DESCRIPTION & APPLICATIONS
Intermediates provide functional groups, building blocks, possibilities for motif modifications, and leaving group to create a desired chemical compound through a series of chemical reactions. 2-Pentenenitrile has a carbon-carbon solid bond and nitrile functional group. Its unsaturated bond enables a series of addition reactions at C 3, producing ethyl branched derivatives including fatty diamines, ether nitriles, ether amines. A large number of inorganic or organic reagents, can be added to this unsaturated bond.

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, reduction to amines, cyclizized to pyridine derivatives.

Pentenenitrile finds applications in dye and flavour & fragrance manufacturing, rubber chemicals, plasticizers and lubricant, solvents  as well as a monomer.
