Procedure

Dichlorosilane in an amount of 83.5 g (0.827 mol), 82.3 g of cyclohexene (1.00 mol), 0.05 mol % of chloroplatinic acid (relative to dichlorosilane) were charged in a 500 ml pressure-proof stainless steel reactor and after sealing, reaction was carried out by heating in an oil bath at 100° C. for 30 hours. After reaction, the seal of the reactor was broken and the reacted liquid was discharged and subjected to vacuum distillation to obtain 139.3 g (0.761 mol) of cyclohexyldichlorosilane having a boiling point of 110°~112° C./155 mmHg.
