Abstract
A process for hydrocyanation of an aliphatic monoethylenically unsaturated compound, in which the ethylenic double bond is not conjugated to any other unsaturated group in the molecule, which process uses a catalyst composition comprising a zero-valent nickel and a multidentate phosphite ligand in the presence of a Lewis acid promoter.
