Procedure

Dichlorosilane in an amount of 83.5 g (0.827 mol), 88.6 g of 1-hexene (1.08 mol) and 0.05 mol % of chloroplatinic acid (relative to dichlorosilane) were charged in a stainless steel reactor and sealed and subjected to reaction in a bath at a temperature of 50° C. for 5 hours. After reaction, the seal of the reactor was broken and the reacted liquid was discharged, and by vacuum distillation, n-hexyldichlorosilane was obtained with a yield of 18% and di-n-hexyldichlorosilane with a yield of 72%.
