Abstract

Novel reactions used to prepare phosphole and bisphosphole compounds are detailed. Novel phosphole compounds and metal coordination compounds of phosphole and bisphosphole compounds are also provided. These metal coordination compounds are useful as catalysts for the polymerization or olefins with carbon monoxide and for the polymerization of acrylic monomers.
