Procedure

In the same apparatus and procedure as Example 1 above, 0.44 g (1.50 mmol) of tetrabutylphosphonium chloride, 0.85 g (7.5 mmol) of 1,3-dichloropropane, and 10.16 g (75.0 mmol) of trichlorosilane were reacted at 150° C. for 10 hrs. The resulting mixture was distilled to give 1.68 g of 1,3-bis(trichlorosilyl)propane (yield; 72%) and 0.22 g of (3-chloropropyl)trichlorosilane (yield; 14%).
