CA 2177135

Processes for hydrocyanation of nonconjugated acyclic aliphatic monoolefins, monoolefins conjugated to an ester group, or monoolefins conjugated to a nitrile group which utilize a catalyst precursor composition comprising a bidentate phosphite ligand and zero-valent nickel preferably in the presence of a Lewis acid promoter. Catalyst precursor compositions are also disclosed.

L'invention a pour objet des procédés destinés à l'hydrocyanuration de mono-oléfines acycliques aliphatiques non conjuguées, de mono-oléfines conjuguées à un groupe ester, ou de mono-oléfines conjuguées à un groupe nitrile, utilisant une composition précurseur de catalyseur comprenant un ligand de phosphite bidentate et du nickel zérovalent de préférence en présence d'un promoteur d'acide de Lewis. L'invention a également pour objet des compositions précurseurs de catalyseur.
