Procedure

A four-necked flask equipped with a condenser, thermometer, gas feed tube, and stirrer was charged with 129.1 g (1.0 mol) of dimethyldichlorosilane and 1.3 g (0.01 mol) of AlCl3, which were agitated with the stirrer. To the flask at room temperature, trimethylsilane which had been synthesized in a separate flask from methylmagnesium chloride and 57.5 g (0.5 mol) of methyldichlorosilane was fed. Agitation was continued for one hour. 2.2 g (0.02 mol) of anisole was added to the reaction solution which was agitated for a further one hour. Dimethylchlorosilane and trimethylchlorosilane were isolated from the reaction solution by distillation. There were obtained 42.0 g of dimethylchlorosilane and 48.9 g of trimethylchlorosilane in a yield of 89% and 90%, respectively.
