Versuchsvorschrift

In a 1-1 flask equipped with a dropping funnel, reflux condenser, stirrer and nitrogen gas introducing tube were placed 149 g (1 mol) of methyltrichlorosilane and 250 ml of diethyl ether. While stirring the mixture, the above chlorotrimethylsilylmethyl magnesium was dropwise added thereto over a period of 2 hours. After completion of the addition, the mixture was refluxed with heating and stirring for 36 hours. After cooling, 200 ml of hexane was added to the reaction mixture, and the salts formed were filtered off. The filtrate was condensed and vaccum-distilled. 11.7 g (yield: 43%) of (trimethylsilylmethyl)methyldichlorosilane was obtained.
