The action of sodium ethoxide in ethanol on a number of(halomethyl)disilanes containing phenyl groups or chloride atoms on silicon has been studied. The reaction proceeds in three directions: intramolecular rearrangement involving migration of a silyl group from silicon to carbon, cleavage of the siliconsilicon bond with concomitant reduction of the halomethyl group to methyl, without evolution of
研究了乙醇中乙醇钠对硅上许多含有苯基或氯原子的(卤甲基)乙硅烷的作用。反应在三个方向上进行:分子内重排,涉及甲硅烷基从硅向碳的迁移;硅硅键的裂解,同时卤代甲基还原为甲基,而不会析出氢;硅硅键的裂解随着氢的释放。重排/切割比例取决于取代基的性质和位置。讨论了可能的机制。
