Patent

CA 2204803

A new family of phospholes having a metalloid bridge to a cyclopentadienyl group is prepared by reacting an organometallic cyclopentadienyl reagent with a "halogenated phosphole" (having a halogen or pseudohalogen group). The new phospholes may be used to prepare organometallic phospholyl complexes. Group 4 metal complexes of these phospholes are excellent polymerization catalysts, especially for the polymerization of olefins at high temperature.
