ABSTRACT:
A system comprisinga) Ni(0)b) from 4 to 10 mol per mol of Ni(0) in a) of a compound (I) of the formulain-line-formulae description="In-line Formulae" end="lead"?P(X1R1)(X2R2)(X3R3)   (I)in-line-formulae description="In-line Formulae" end="tail"?whereX1, X2, X3are each, independently of one another, oxygen or a single bond,R1, R2, R3are, independently of one another, identical or different organic radicalsandc) from 1 to 4 mol per mol of Ni(0) in a) of a compound (II) of the formulawhereX11, X12, X13X21, X22, X23are each, independently of one another, oxygen or a single bond,R11, R12are identical or different, individual or bridged organic radicals,R21, R22are identical or different, individual or bridged organic radicals andY is a bridging groupis suitable as catalyst for preparing mixtures of monoolefinic C5mononitriles having nonconjugated C═C and C═N bonds by hydrocyanation of a 1,3-butadiene-containing hydrocarbon mixture and for preparing a dinitrile by hydrocyanation of a mixture of monoolefinic C5mononitriles having nonconjugated C═C and C═N bonds.
