Abstract
Aromatic chlorosilanes are prepared by reacting a benzenoid hydrocarbon with an organodichloromonohydrosilane in the presence of a boron halide at a temperature above 150 DEG C., under sufficient pressure to ensure that at least a portion of the reaction mixture is in a condensed phase, to produce an organodichlorosilyl derivative of the benzenoid hydrocarbon. The temperature employed may be between 150 DEG and 420 DEG C. or 150 DEG and 300 DEG C. Suitable benzenoid hydrocarbons are benzene, polyphenyls, and alkyl substituted benzenes such as toluene, xylene, cumene and mesitylene. The boron halide may be formed in situ by the addition of boric acid or boron trioxide. In the examples the following compounds are prepared: phenylmethyldichlorosilane, bis-(methyldichlorosilyl)-benzene, diphenyldichlorosilane, bis-(phenyldichlorosilyl)-benzene, diethylphenyl phenyl dichlorosilane, o-, m- and p-tolylmethyldichlorosilanes, bis - (methyldichlorosilyl) - toluenes, diphenylylmethyldichlorosilanes, bis-(methyldichlorosilyl)-diphenyls and compounds of the general formula <FORM:0646629/IV (b)/1> Specifications 632,824 and 645,972 are referred to.
