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.

A palladium complex with an optically active ligand catalyzes asymmetric hydrosilylation of 1,3-dienes using difluoro(phenyl)silane to give optically active allyl difluoro(phenyl)silanes in good enantiomeric excess.Keywords: Chirality; Fluorine; Silane; Ferrocene; Silicon; Palladium
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.

Tertiary and secondary silanes are O-selective.With alcohols the corresponding silyl ethers are formed.Cesium fluoride/imidazole)CsF/Im) is a better activating system than CsF alone.Primary OH groups are silylated remarkably faster under CsF/Im activation
