Reactions of dodecamethylcyclohexasilane and polydimethylsilane with metal chlorides

The reactions of dodecamethylcyclohexasilane and high-molecular-weight polydimethylsilane with chlorides of I, II, IV-VI and VIII Group metals at high temperature in the absence of a solvent were studied. The interaction of (Me2Si)6 with metal chlorides proceeds with the cleavage of Si-Si and Si-C bonds with the formation of chloro derivatives of linear and cyclic permethyloligosilanes. The reactions of polydimethylsilane with metal chlorides afford mixtures of α,ω-dichlorooligosilanes, Cl(Me2Si)nCl (n=2-9). The influence of the reaction conditions (temperature, reaction time and the reagent ratio) on the composition and yields of the reaction products was examined.

The behaviour of medium-sized permethylated cyclosilanes towards SOCl2 and SOCl2-HC(OCH3)3

Treatment of Si6Me12 with SOCl2 in various solvents gives α,ω-dichloropermethylpolysilanes (nSi = 2,3,4,6) at temperatures above 80 deg C.In contrast to an earlier report, treatment of the α,ω-dichloropermethylpolysilanes with HC(OCH3)3 in the presence of SOCl2 does not give Si6Me12.
