Ammonium Chloride → HCID 131727207、化合物

The THF solution of cyclohexyl magnesium chloride as prepared above was added dropwise to the methylmethoxydichlorosilane solution obtained in Example 7, in the same manner as in Example 3(c), to effect the Grignard reaction. The post-treatment of the resulting Grignard reaction solution was carried out in the same manner as in Example 3(c), except that the saturated aqueous ammonium chloride solution used in Example 3(c), was used in a reduced amount of 80 ml instead of 120 ml. The organic layer was separated and was fractionally distilled under a reduced pressure, thereby to afford 39 g of dicyclohexylmethylmethoxysilane as a fraction boiling at 128° C.-129° C./7 mm Hg (yield; 80%).
