Abstract

The synthesis and characterization of the new silylene(isodicyclopentadienyl)(fluorenyl)zirconium dichloride ( 5 ) have been performed. This complex has been characterized by 1 H and 13 C NMR spectroscopy and its solid-state molecular structure has been determined. After activation by methylalumoxane, 5 is shown to initiate the polymerization of ethylene and propylene. S-PP is produced. Quite unusual for a silylene-bridged zirconium complex, good syndiotacticity was observed for propylene polymerization.
