Versuchsvorschrift

In the same apparatus and procedure as Example 1 above, 0.20 g (0.75 mmol) of triphenylphosphine, 0.92 g (7.5 mmol) of (chloromethyl)trichlorosilane, and 5.08 g (37.5 mmol) of trichlorosilane were reacted at 150° C. for 42 hrs. The resulting mixture was distilled to give 1.1 g of 1,1,1,3,3,3-hexachloro-1,3-disilapropane (bp; 173-174° C., yield; 50%) and 0.3 g of 1,1,1,3,3-pentachloro-1,3-disilapropane (bp; 166-167° C., yield; 16%).
