A method for the preparation of a cycloalkyl silane compound.

摘要

Cycloalkyl silane compound such as cyclohexyl methyl dichlorosilane can be efficiently prepared by the photochemically induced hydrosilylation reaction. For example, an equimolar mixture of cyclohexene and methyl dichlorosilane and admixture of a catalytic amount of a platinum compound, e.g., chloroplatinic acid, is irradiated at a temperature up to 70 DEG C with ultraviolet light so that the hydrosilylation reaction takes place and proceeds almost to completeness without deactivation of the platinum catalyst to give the desired product in a yield of 90% or even higher.
