M(CO)6–RCln–hν catalysts (M = W, Mo; RCln= PhCCl3, Ph2CCl2): new catalyst systems for the metathesis polymerization of substituted acetylenes and cycloalkenes

Abstract

The M(CO)₆–RCl_n-hν systems (M = W, Mo; RCl_n= PhCCl₃, Ph₂CCl₂) work as effective catalysts for the polymerizations of substituted acetylenes and norbornene to provide high molecular weight polymers in good yields, where RCl_n are sufficient in catalytic amounts unlike CCl₄.
