- Selective synthesis of halosilanes from hydrosilanes and utilization for organic synthesis
-
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.

- DARSTELLUNG UND CHARAKTERISIERUNG DER PHENYLFLUORDISILANE Si2Ph6-nFn
-
Fluorination of chlorophenyldisilanes with ZnF2 yields the corresponding fluorophenyldisilanes, if silver powder is used as a catalyst. 1,2-Difluorotetraphenyldisilane is synthesized by UV irradiation of bis-(fluorodiphenylsilyl)mercury, the first known fluorosilylmercury compound.All the eight possible fluorophenyldisilanes, unknown up to now, are characterized by spectroscopic methods.
