HCID 2756737Bis(trichlorosilyl)methaneYield 68%

Procedure

In the same apparatus and procedure as Example 1 above, 0.22 g (0.67 mmol) of benzyltributylphosphonium chloride, 1.23 g (6.69 mmol) of (chloromethyl)trichlorosilane, and 2.71 g (20.0 mmol) of trichlorosilane were reacted at 160° C. for 15 hrs. The resulting mixture was distilled to give 1.13 g of 1,1,1,3,3,3-hexachloro-1,3-disilapropane (yield; 68%).

Workup
