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 use of salt elimination, the transition-metal-substituted cyclopentasilanes Me9Si5-Co(CO)3PPh3. Me9Si5-Fe(CO)2Cp, Me9Si5-SiMe2Co(CO)3PPh3 and Me9Si5-SiMe2Fe(CO)2Cp were prepared and characterized.
