Abstract
A halosilane compound: R1CH2CH2SiR52X is prepared by hydrosilylation reaction of a vinyl compound: R1CH═CH2 with a halogenodiorganosilane compound having formula: HSiR52X in the co-presence of an iridium catalyst, an internal olefin compound, and an allyl halide. The halosilane compound is prepared on an industrial scale with the advantages of low costs, high yields, and high selectivity, using a small amount of iridium catalyst.
