BIDENTATE PHOSPHITE AND NICKEL CATALYST COMPOSITIONS FOR HYDROCYANATION OF MONOOLEFINS

摘要

Processes for hydrocyanation of nonconjugated aliphatic monoolefins or monoo lefins conjugated to an ester group utilizing a catalyst precursor composition comprising an unsymmetrical bidentate phosphite ligand and zero-valent nickel, preferably in the presence of a Lewis acid promoter, to produce a terminal organo-nitrile. Catalyst precursor comp ositions are also disclosed.
