Procedure

In the same apparatus and procedure as Example 1 above, 0.44 g (1.50 mmol) of tetrabutylphosphonium chloride, 1.18 g (7.50 mmol) of 1-bromo-3-chloropropane, and 10.16 g (75.0 mmol) of trichlorosilane were reacted at 150° C. for 4 hrs. The resulting mixture was distilled to give 1.21 g of 1,3-bis(trichlorosily)propane (yield; 52%), 0.17 g of 3-(bromopropyl)trichlorosilane (yield; 9%), and 0.16 g of 3-(chloropropyl)trichlorosilane (yield; 10%).
