A number of undecamethylcyclohexasilanyl-substituted silanes have been prepared employing a salt elimination reaction between undecamethylcyclohexasilanyl potassium and several silyl halides or triflates. This method provides access to compounds with one or two undecamethylcyclohexasilanyl units attached to one silicon atom. Several attempts to introduce a third ring failed, resulting in formation
A simple way for the preparation of undecamethylcyclohexasilanylalkalimetal compounds is described by the reaction of dodecamethylcyclohexasilane with alkalimetal alcoholats in glyme solvents. Reactions of other cyclosilanes are also discussed. Some reactions of undecamethylcyclohexasilanylpotassium with element-halogen derivates and inorganic acids are described.

To study the behaviour of some cyclosilanes containing Si-H bonds in dehydrogenative polymerization, cyclosilanes with Si-H bonds directly on the ring and cyclosilanes with Si-H bonds in silyl- and disilanyl side chains were synthesized and characterized by the usual spectroscopic and analytical methods. The ease of the polymerization is affected by steric hindrance and oligomers can be formed along with other side products. Only 1,4-bis(silyl)decamethylcyclohexasilane gave a polymer. Cp(2)HfCl(Si(6)Me(11)) was prepared for use as a catalyst.
