Versuchsvorschrift

In the same apparatus and procedure as Example 1 above, 0.20 g (0.75 mmol) of triphenylphosphine, 1.38 g (7.5 mmol) of (chloromethyl)trimethylsilane, and 5.08 g (37.5 mmol) of trichlorosilane were reacted at 150° C. for 10 hrs. The resulting mixture was distilled to give 1.2 g of 1,1,1,-trichloro-3,3-dimethyl-1,3-disilabutane (bp; 173-174° C., yield; 70%) and 0.1 g of 1,1-dichloro-3,3-dimethyl-1,3-disilabutane (bp; 157-159° C., yield; 7%).
