ABSTRACT:
A polysilane is produced by subjecting a trihydrosilane to hydrogenative condensation in the presence of a titanium or zirconim complex catalyst having a first group selected from a dialkylaminoalkylcyclopentadienyl group, an .alpha.-[(dialkylamino)alkyl]indenyl group and a .beta.-[(dialkylamino)alkyl]indenyl group and a second group selected from a cyclopentadienyl group and a pentamethylcyclopentadienyl group. The above dialkylaminoalkyl group may be replaced by a branched alkyl group. The zirconium complexes are novel compounds.
