    摘要： Tetrakis(trimethylsilyl)silane is prepared by reacting tetrachlorosilane with chlorotrimethylsilane in the presence of lithium metal, adding a compound with active proton(s) to the reaction mixture for treating the residual lithium metal therewith while maintaining the mixture neutral or acidic, and separating tetrakis(trimethylsilyl)silane from the organic layer. The residual lithium metal is treated in a safe and simple manner. Reaction of the tetrakis(trimethylsilyl)silane with an alkyl lithium or alkali metal alkoxide, followed by acid hydrolysis, affords tris(trimethylsilyl)silane. The desired compounds are prepared in high yields and on an industrial scale.
