Reactions of hydrosilanes, R4-nSiHn (R = alkyl or phenyl, n = 1-3), with 2 equiv of CuBr2 in the presence of a catalytic amount of CuI led to selective replacement of an H-Si bond with a Br-Si bond giving R3SiBr, R2SiHBr, or RSiH2Br, while treatment of R2SiH2 and RSiH3 with 4 equiv of the reagent produced R2SiBr2 and RSiHBr2, respectively. Similar reaction of HEt2SiSiEt2H afforded HEt2SiSiEt2Br.
The Mechanism of the Reaction of Molecular Bromine with Organosilicon Hydrides

The kinetics of the bromination of 7 triarylsilanes and 14 other organosilicon hydrides by molecular bromine in CCl4 have been determined by the stopped flow method.For triethylsilane, Arrhenius parameters have been measured in octane and CCl4, and solvent effects determined in other solvents of different polarity.The results accord with a molecular mechanism involving one molecule of bromine and one of the organosilicon hydride, with partial positive charge build-up on silicon in the transition state.
