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.

cyclo-Si5Me8ClSiMe2Cl (III). Treatment with [Fe(CO)2Cp]− produced cyclo-Si5Me9SiMe2[Fe(CO)2Cp] (II) and cyclo-Si5Me8[Fe(CO)2Cp]SiMe2[Fe(CO)2Cp] (IV). The structures of II and IV were determined by single crystal X-ray diffraction. Compound II crystallizes in the monoclinic space group P21/c with a 21.531(9) Å, b 9.865(4) Å, c 13.917 Å, β 101.67(2)°, V 2895(2) Å3 and with Z = 4. Compound IV crystallizes
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.
