Procedure

In the same apparatus and procedure as Example 1 above, 0.20 g (0.75 mmol) of triphenylphosphine, 1.07 g (7.5 mmol) of (chloromethyl)methyldichlorosilane, and 5.08 g (37.5 mmol) of trichlorosilane were reacted at 150° C. for 24 hrs. The resulting mixture was distilled to give 1.0 g of 1,1,1,3,3-pentachloro-1,3-disilabutane (bp; 181-182° C., yield; 58%) and 0.1 g of 1,1,3,3-tetrachloro-1,3-disilabutane (bp; 166-167° C., yield; 14%).
