摘要：

The reaction of MCl4 (M = Zr, Hf) with the dilithium salt of 1-cycolopentadienyl-1-fluorenyl-1,1-diphenylmethane in pentane at ambient temperature leads to the formation of the complexes (eta5-C5H4CPh2-eta5-C13H8)MCl2. NMR and X-ray diffraction data confirm that the fluorenyl groups are eta5-bonded in these complexes. When activated with aluminoxane or other appropriate ionizing agents both complexes catalyze the stereospecific polymerization of propylene to syndiotactic polypropylene of high molecular weight and tacticity.
