The reactions between alkyltin hydrides and a variety of polyhalo-and mixed halosilanes have been investigated. For SiCI, and SiCI3H, the reductions proceed in a stepwise manner to yield the monoreduced species as the major products. The reduction of SiBr, occurs much faster to yield a mixture of SiBr, H and SiH,, or, in the vapor phase, SiBr3H as the sole product. SiF3X (X= Br, CI) is converted into SiF3H, with no further reduction of SiF3H ...
