Ring contraction of cyclohexasilanes to silylcyclopentasilanes and the preparation of monofunctional nonamethylcyclopentasilanes
Abstract
Dodecamethylcyclohexasilane undergoes ring contraction 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 monofunctional nonamethylcyclopentasilanes.
