  Selective synthesis of halosilanes from hydrosilanes and utilization for organic synthesis

  摘要：

  Selective synthesis of halosilanes has been examined. Various types of halosilanes and halohydrosilanes, such as R3SiX, R2SiHX, R2SiX2, RSiH2X, RSiHX2 (X = Cl, Br, F), were obtained by the reactions of the corresponding hydrosilanes with Cu(II)-based reagents selectively in high yields. This method could be also applied to the synthesis of chlorofluorosilanes and chlorohydrogermanes. On the other hand, iodo- and bromosilanes and germanes were obtained by Pd- or Ni-catalyzed hydride-halogen exchange reactions of hydrosilanes with alkyl or allyl halides. Their synthetic applications have been demonstrated by using iodo-and bromosilanes and chlorofluorosilanes. (C) 2003 Elsevier Science B.V. All rights reserved.

• Method for the chlorination of a silicon compound

  A novel method is proposed for the chlorination of a silicon compound having, in a molecule, at least one hydrogen atom directly bonded to the silicon atom. The method comprises the step of reacting the starting silicon compound with anhydrous copper (II) chloride as a chlorinating agent in the presence of copper (I) iodide as a catalyst so as to substitute a chlorine atom for the silicon-bonded hydrogen atom. When the starting silicon compound has two or more of silicon-bonded hydrogen atoms, the chlorination reaction proceeds stepwise so that the inventive method provides a possibility of selective chlorination.

  提出了一种新的方法，用于氯化具有分子中至少一个氢原子直接与硅原子键合的硅化合物。该方法包括以下步骤：在铜(II)氯作为氯化剂的存在下，将起始硅化合物与碘化铜(I)作为催化剂反应，以取代硅键合氢原子的氯原子。当起始硅化合物具有两个或更多硅键合氢原子时，氯化反应逐步进行，因此该创新方法提供了选择性氯化的可能性。
