Dodecamethylcyclohexasilane undergoes ringcontraction with aluminium chloride as catalyst in the presence or absence of trimethylchlorosilane to give, respectively, chlorodimethylsilyl- or trimethylsilyl-cyclo-pentasilane, the former being convertible into monofunctionalnonamethylcyclopentasilanes.

By means of the new possibility to split a trimethylsilyl group from the methylated cyclopentasilane by action of EtONa, a new, simple, and effective pathway to valuable molecules for other syntheses was found.
