colourless liquid

Uses

4-Pentenenitrile may be used to synthesize 4-pentenylamine.

General Description

4-Pentenenitrile (4-PN) is a terminal alkene nitrile. It is obtained from 3-pentenenitrile via cationic nickel hydride or cobalt catalyzed isomerization. 4-Pentenenitrile undergoes hydrocyanation in the presence of bidentate nickel complexes (catalysts) to yield 3-pentenenitrile. 4-PN undergoes gas-phase reaction with OH radicals and Cl atoms in the presence of synthetic air and various reference compounds.
