Abstract
Alkyl cycloalkyl dialkoxysilanes (e.g., methyl cyclohexyl dimethoxysilane) can be prepared by reaction of an alkyl trialkoxysilane (e.g., methyl trimethoxysilane) with a Grignard reagent containing the cycloalkyl moiety derived in the final end-product (e.g., a reagent formed by reacting cyclohexyl chloride and magnesium metal). The reaction is run in the absence of ether solvent, the Grignard reagent is preferably formed in situ by the reaction of magnesium metal and cyclohexyl halide, and agitation is used to promote the reaction. Advantageously, a catalyst, such as iodine, is used to promote the reaction.
