A system comprising a) Ni(0) b) from 4 to 10 mol per mol of Ni(0) in a) of a compound (I) of the formula <?in-line-formulae description="In-line Formulae" end="lead"?>P(X<SUP>1</SUP>R<SUP>1</SUP>)(X<SUP>2</SUP>R<SUP>2</SUP>)(X<SUP>3</SUP>R<SUP>3</SUP>) (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where X<SUP>1</SUP>, X<SUP>2</SUP>, X<SUP>3 </SUP>are each, independently of one another, oxygen or a single bond, R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3 </SUP>are, independently of one another, identical or different organic radicals and c) from 1 to 4 mol per mol of Ni(0) in a) of a compound (II) of the formula where X<SUP>11</SUP>, X<SUP>12</SUP>, X<SUP>13 </SUP>X<SUP>21</SUP>, X<SUP>22</SUP>, X<SUP>23 </SUP>are each, independently of one another, oxygen or a single bond, R<SUP>11</SUP>, R<SUP>12 </SUP>are identical or different, individual or bridged organic radicals, R<SUP>21</SUP>, R<SUP>22 </SUP>are identical or different, individual or bridged organic radicals and Y is a bridging group is suitable as catalyst for preparing mixtures of monoolefinic C<SUB>5 </SUB>mononitriles 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 C<SUB>5 </SUB>mononitriles having nonconjugated C-C and C-N bonds. |
