Abstract

A method for preparing a tertiary hydrocarbon-silyl compound comprises the step of reacting a grignard reagent represented by the general formula: R.sup.1 MgX.sup.1 (wherein R.sup.1 represents a tertiary hydrocarbon group and X.sup.1 is a halogen atom) with a silicon atom-containing compound represented by the general formula: X.sup.2.sub.m R.sup.2.sub.n SiH.sub.4-m-n (wherein X.sup.2 is a halogen atom and may be identical to or different from X.sup.1 ; R.sup.2 is a monovalent hydrocarbon group; m is 1, 2 or 3; and n is 0, 1 or 2, provided that m+n is not more than 3 and that if n is 2, R.sup.2 's may be identical to or different from one another) in an aprotic inert organic solvent in the presence of a copper compound and/or a quaternary ammonium salt. According to this method, the tertiary hydrocarbon-silyl compounds can industrially efficiently and rapidly produced in high yields.
