摘要：
The synthesis, characterization and X-ray structures of two zirconium complexes of the bulky pentaphenylcyclopentadienyl ligand, C-P(PRO), are reported. The monocyclopentadienyl 12 electron complex, (CPZrCl3)-Zr-PRO (I), has an unusual monomeric structure in the solid state and has short Zr-ligand distances. The Lewis acidity of this complex is manifested in its ability to catalyze the [4 + 2] cycloadditions of methyl- and ethylmethacrylate to cyclopentadiene. The sandwich complex, (CPCpZrCl2)-Cp-PRO (II), has more typical Zr-ligand distances, but has a more parallel arrangement of the two cyclopentadienyl rings. (C) 1999 Elsevier Science S.A.
