Procedure

A flask equipped with a stirrer, reflux condenser, dropping funnel and thermometer was charged with 111.6 g (0.50 mol) of 4-(2-methyldichlorosilylethyl)-1-cyclohexene and 0.1 g of a 20 wt % isopropanol solution of chloroplatinic acid, which were heated at 80° C. After the internal temperature became constant, 63.3 g (0.55 mol) of methyldichlorosilane was added dropwise over 5 hours. After the completion of addition, the reaction solution was stirred for 8 hours at 80° C. The reaction solution was distilled, collecting 136.0 g of (2-methyldichlorosilylethyl)methyldichlorosilylcyclohexane as a fraction having a boiling point of 122-124° C./0.1 mmHg (yield 80.4%).
