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, 100 ml of toluene, 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 methyl-magnesium chloride and 57.5 g (0.5 mol) of methyldichlorosilane was fed. Agitation was continued for one hour. 2.8 g (0.02 mol) of o-dimethoxybenzene 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 42.6 g of dimethylchlorosilane and 47.3 g of trimethylchlorosilane in a yield of 90% and 87%, respectively.
