Abstract:
A process for the production of a polysilane compound represented by the following formula (VII): ##STR9## wherein R.sup.4 represents an alkyl group having no more than 12 carbon atoms, an aryl group having no more than 12 carbon atoms, a cycloalkyl group having no more than 12 carbon atoms or an aralkyl group having no more than 12 carbon atoms and n is an integer of at least 8, said process comprising subjecting a trihydrosilane represented by the following formula (VI):R.sup.4 SiH.sub.3 (VI)wherein R.sup.4 is as defined above, to hydrogenative condensation in the presence of a metal complex catalyst represented by the following formula (VIII): ##STR10## wherein M represents zirconium or titanium, L.sup.1 represents a first group selected from the group consisting of (a) a group represented by the following formula (I): ##STR11## wherein R.sup.1 stands for an alkyl group having no more than 3 carbon atoms, X stands for N or CH and p represents an integer of 4 or less, (b) a group represented by the following formula (II): ##STR12## wherein R.sup.2 stands for an alkyl group having no more than 3 carbon atoms, Y stands for N or CH and q represents an integer of 4 or less, and (c) a group represented by the following formula (III): ##STR13## wherein R.sup.3 stands for an alkyl group having no more than 3 carbon atoms, Z stands for N or CH and m represents an integer of 4 or less, L.sup.2 represents a second group selected from the group consisting of (d) a cyclopentadienyl group represented by the formula (IV): ##STR14## and (e) a pentamethylyclopentadienyl group represented by the formula (V): ##STR15## and L.sup.3 and L.sup.4 are each a monodendate anionic ligand.
