Abstract	AbstractThe catalytic dehydrocoupling of bis(1-sila-3-butyl)benzene 1 and 2-phenyl-1,3-disilapropane 2 by Cp 2 ZrCl 2 /Red-Al andCp 2 ZrCl 2 /n-BuLi was reported to compare their catalytic efficiency. The dehydrocoupling of monomeric silanes 1 withthe Cp 2 ZrC1 2 /Red-Al and Cp 2 ZrCl 2 /n-BuLi combination catalysts produced two phases of polymers: one is a highly cross-linked insoluble solid, and the other is noncross-linked or slightly cross-linked soluble oil and could be a precursor forthe solid polymer. The dehydrocoupling of 2 with the Cp 2 ZrCl 2 /n-BuLi combination catalyst similarly produced two phasesof polymers. By contrast, the catalytic reaction of 2 with the Cp 2 ZrCl 2 /Red-Al combination catalyst produced a solublepolymer via redistribution/dehydrocoupling process.Key words : Dehydrocoupling, Catalyst, Polymers, Silanes 1. Introduction Inorganic polymers with various superior propertiesover organic polymers have been employed for manyadvanced applications [1] . Especially, polysilanes pos-sessing unusual optoelectronic properties attributed toelectron-conjugation along the silicon backbone haveparticularly received extensive attentions as SiCceramic precursors
