Abstract
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 a fford high-molecular-weight poly(phenylsilanes)(M-w > 10(4)). Si-29 NM R reveals that the microstructure of the resulting polymers is predomi nantly syndiotactic.
