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.
Ring-opening reactions of alkanone acetals with iodosilane equivalents for the formation of siloxyalkyl enol ethers

Reactions of ketone acetals with iodosilane equivalents were studied. Treatment of alkanone ethylene acetals with a 1:2 mixture of Et2NSiMe3 and MeI afforded 2-siloxyethyl enol ethers in good yield. Benzophenone ethylene acetal underwent deprotection with the iodosilane equivalents, giving benzophenone.
General Method for the Synthesis of Enol Ethers (Vinyl Ethers) from Acetals
Gassman, Paul G.,Burns, Stephen J.
, p. 5574 - 5576 (2007/10/02)
A general, high yield method for the synthesis of enol ethers from acetals has been devised that involves treatment of an appropriate acetal with a 10-75percent molar excess of trimethylsilyl triflate and a 20-90percent molar excess of N,N-diisopropylethy
