摘要：

New zirconocene complexes Cp*[Cp(CH2)(n)-NMe2]ZrCl2 (n = 2, 3) and Cp*[Cp(CH2)(n)CH(CH3)(2)]-ZrCl2 (n = 2, 2) catalyze, in conjunction with 2 equiv of n-BuLi, dehydrocoupling polymerization of phenylsilane to afford high-molecular-weight poly(phenylsilanes)(M-w > 10(4)). Si-29 NMR reveals that the microstructure of the resulting polymers is predominantly syndiotactic.
