14 Claims

1. A system which is suitable as a catalyst for the hydrocyanation of olefinically unsaturated compounds and comprises;

a) Ni(0),

b) a compound which complexes Ni(0) as a ligand and comprises phosphites, phosphonites or mixtures thereof,

c) a Lewis acid

and

d) a compound of the formula M R_n, where

c) and d) are different, and

where

M is selected from Al or Ti,

R is selected from identical or different monovalent alkoxy radicals, in which the alkoxy radicals may be bonded together, and if M=Al, R may also be identical or different monovalent alkyl radicals, in which the alkyl radicals may be bonded together or one or more alkyl radicals may be bonded to one or more of the abovementioned alkoxy radicals, and

n is the valency of M.
