Procedure

A reactor was charged with 42.3 grams (0.30 mol) of methylvinyldichlorosilane and 0.1 ml of a 2.ethylhexyl alcohol solution containing 2% chloroplatinic acid. To the reactor was added dropwise 34.5 grams (0.30 mol) of methyldichlorosilane. After the completion of addition, stirring was continued for a further one hour. After cooling, the reaction solution was distilled, obtaining 74.5 grams (yield 97%) of 1,2-bis(methyldichlorosilyl)ethane having a boiling point of 109°-110° C./30 mmHg.
