METHOD FOR PRODUCING MIXTURES OF MONOOLEFINIC C 5?-MONONITRILES BY CATALYTIC HYDROCYANATION IN THE PRESENCE OF A CATALYST CONTAINING AT LEAST ONE METALLOCENE PHOSPHOR (III)-NICKEL-(0) COMPLEX

摘要

A process for preparing mixtures of monoolefinic C5 mononitriles with nonconjugated C=C and C=N bonds by catalytic hydrocyanation of 1,3-butadiene or a 1,3-butadiene-containing hydrocarbon mixture, wherein the hydrocyanation takes place in the presence of a catalyst which comprises at least one metallocene-phosphorus(III)-nickel(0) complex which comprises at least one monodentate or bidentate metallocene-phosphorus(III) ligand of the formula Ior salts and mixtures thereof.
