Dichlorodimethylsilane → Chlorotriethylsilane

Participants

Reaction Steps

A four-necked flask was equipped with a condenser, thermometer, dropping funnel, and stirrer was charged with 12.9 g (0.10 mol) of dimethyldichlorosilane and 0.27 g (0.002 mol) of AlCl3, which were agitated with the stirrer. To the flask at room temperature, 5.8 g (0.05 mol) of triethylsilane was added dropwise over 30 minutes. Thereafter, agitation was continued for one hour while the flask was kept at 30° C. 0.28 g (0,002 mol) of o-dimethoxy-benzene was added to the reaction solution which was agitated for a further one hour. Dimethylchlorosilane and triethylchlorosilane were isolated from reaction solution by distillation. There were obtained 3.78 g of dimethylchlorosilane and 7.37 g of triethylchlorosilane in a yield of 80% and 98%, respectively.
