CATALYST COMPRISING AT LEAST ONE PHOSPHONITE LIGAND BASED NICKEL (O) COMPLEX AND METHOD FOR THE PRODUCTION OF NITRILES

摘要

The invention relates to a catalyst, comprising at least one nickel (O) complex containing at least one monodentate, bidentate or multidentate phosphonite ligand of general formula (I) or the salts or mixtures thereof. The invention also relates to a method for producing said catalysts and to a method for producing monoolefinic C5-mononitriles with a non conjugated C=C and CN -bond by catalytic hydrocyanation of butadiene or a hydrocarbon mixture containing 1.3 butadiene, characterised in that hydrocyanation occurs in the presence of one such catalyst.
