た。That is, as a result of various studies on efficient production methods of tert-butylmethyldimethoxysilane, the present inventors found that when tert-butylmethylchlorosilane and methanol are reacted in the presence of a magnesium compound, a reaction occurs due to the catalytic action of the magnesium compound. Tert-butylmethyldimethoxysilane can be easily obtained in a high yield through the process, and in this case there is no conversion of methyl groups to iCH2 groups, so the desired tert-butylmethylmethoxysilane can be obtained with high purity. The present invention was completed by conducting research on reaction conditions such as the type of magnesium compound used and the amount added.
