Abstract
A process for the preparation of more highly alkylated silanes and disilanes. The process comprises (A) contacting a halodisilane, with an alkyl halide in the presence of a metal, such as aluminum, which serves as a halogen acceptor, (B) reacting the halodisilane with the alkyl halide in the presence of the metal at a temperature greater than about 150.degree. C. to form the more highly alkylated silanes and disilanes and a metal halide; and (C) isolating and separating the more highly alkylated silanes and disilanes.
