Neutral Nickel(II)-Based Catalysts for Ethylene Polymerization

Abstract

Neutral salicylaldiminato Ni(II) complexes have been synthesized, and their structure has been confirmed by an X-ray analysis of complex 4e. These compounds are active catalysts for the polymerization of ethylene under mild conditions in the presence of a phosphine scavenger such as Ni(COD)2 or B(C6F5)3.
