摘要：

One unbridged and three bridged zirconocene complexes, each of them bearing a cyclopentadienyl, fluorenyl, alpha-olefin and a PMe(3) ligand have been prepared and characterized by H-1, C-13 and P-31 NMR spectroscopy. These model compounds illustrate the mechanism of olefin coordination and insertion at the active sites of syndiospecific homogeneous catalysts for the polymerization of propylene and 1-butene.
