摘要

Process for the preparation of complex nu00ecquel (0) - phosphorus ligand, and use of mixtures which comprise complexes of nu00ecquel (0) - ligand of match.Process for the production of complexes of nickel (o) - phosphorus ligand that include at least one central atom of nickel (o) and at least one ligand containing phosphorus by reaction of a compound of nickel (II) with a reducing agent in the presence of ligand to provide a mixture of reau00e7u00e3 The, characterized by the fact that,(a) in the reaction, the molar ratio of reducing agent: composed of nickel (II) is 1: 1 to 1000: 1, calculated as the molar ratio of redox equivalents, (b) in the reaction, the molar ratio of ligand containing phosphorus: composed of nickel (II) is in a maximum of 30: 1, calculated as the molar ratio of u00e1to Let P: atoms of Ni, c) in the reaction mixture resulting from the content of nickel (0) is at most 13% by weight, and (d) mixing the resulting reaction is extracted by adding at least one dinitrila and at least a hydrocarbon forming at least two immiscible phases.
