実験手順

The sec-butyl magnesium chloride as prepared above was added dropwise to the methylmethoxydichlorosilane solution as obtained in Example 7, in the same manner as in Example 3(c), to effect the Grignard reaction. The resulting Grignard reaction solution was post-treated with the saturated aqueous ammonium chloride solution as used in Example 3(c) in a reduced amount of 80 ml, instead of the 120 ml. The organic layer was separated and was subjected to a fractional distillation, thereby to afford 31 g of di-sec-butyl methylmethoxysilane as a fraction boiling at 76° C.-78° C./16 mmHg (yield; 80%).
