<p>A system suitable for use as a catalyst for the hydrocyanation of olefinically unsaturated compounds, containing a) Ni(0), b) Ni(0) as a ligand complex-fixing compound containing trivalent phosphorus, c) a Lewis acid and d) a compound of formula MRn wherein M = AI or Ti, R= identical or different monovalent alkoxyl radicals, wherein several alkoxy radicals can be interbridged, also in the case where M = AI, R = identical or different alkyl radicals wherein several alkyl radicals can be interbridged or one or several alkyl radicals can be bridged by one or several of the above-mentioned alkoxy radicals, n = valency of M. The invention also relates to methods for the hydrocyanation of an olefinically unsaturationed compound in the presence of said system.</p> |
