ABSTRACT:
Silicon halides and silicon hydrohalides, such as SiCl.sub.4, SiBr.sub.4, and SiHCl.sub.3 react with alkali metal aluminum hydrides such as NaAlH.sub.4 and LiAlH.sub.4 in the presence of a hydrocarbon reaction medium; e.g., toluene, and a tetraalkyl ammonium salt, and in the substantial absence of an ether, to produce silane and a metal aluminum halide co-product which is not tightly complexed to an organic substance.
