실험 절차

There was allowed 100 g (1.0 mmol) of trimethylsilyl ethene to react with 127 g (1.1 mol) of methyldichlorosilane in a 500-ml flask equipped with a dropping funnel, reflux condenser, stirrer and nitrogen gas introducing tube, by steps of placing 20 ml of a mixture of trimethylsilyl ethene and methyldichlorosilane and 0.0051 g (0.01 mmol) of chloroplatinic acid in the flask, adding dropwise the remaining mixture of trimethylsilyl ethene and methyldichlorosilane thereto over a period of 4 hours while stirring the reaction mixture, and continuing the stirring for another 1 hour to complete the reaction. Subsequently, 200 ml of hexane was added to the reaction mixture, and the catalyst precipitated was filtered off. The filtrate was condensed and vaccum-distlled. 145 g (yield: 75%) of (2-trimethylsilylethyl)methyldichlorosilane was obtained.
