  Synthesis of unsymmetrical 1,2-bis(diorganochlorosilyl)ethanes

  摘要：

  Unsymmetrical 1,2-bis(diorganylsilyl)ethanes were synthesized by two procedures. Hydrosilylation of chloro(vinyl)silanes were used to obtain compounds of the general formula ClMe2SiCH2CH2SiRMeCl with different substituents (R = Et, Vin, Ph) on the silicon atom. Chlorodealkylation of 1,2-bis(trialkylsilyl)ethanes gave compounds of the general formula ClAlk(2)SiCH(2)CH(2)SiAlk(2)Cl (Alk = Me, Et, Pr). It is established that the latter reaction provides high yields only with Me- and Et-substituted compounds, whereas Pr-substituted products are formed in poor yields. The mechamism of this reaction based on quantum-chemical calculations is offered.
