ABSTRACT:
The preparation of branched unsaturated dinitriles as the major products (along the branched saturated dinitriles as the by-products) is achieved by electrolytic coupling of unsaturated mono nitriles in acetonitrile. All dinitrile products have an odd number of carbons between the two nitrile groups. The starting aliphatic unsaturated nitriles include 2-pentenenitrile, 3-pentenenitrile, 2-butenenitrile and 3-methyl-2-butenenitrile.
