摘要

Kinetic and mechanistic studies for the previously reported (dfepe)Pt(Me)(NC5F5)+ ethylene dimerization catalyst system and a general extension to other chelating diphosphine analogues (PP)Pt(Me)(C2H4)+are presented. Underlying factors for relative ethylene insertion barriers for diimine and diphosphine systems are evaluated.
