Procedure

Hydrosilation of acetylene with bis(dichlorosilyl)trichlorosilylmethane in the presence of Pt(C2H4)(PPh3)2. Into the same apparatus as described in Example 1 were placed 0.103 g of Pt(C2H4)(PPh3)2, 2.99 g of bis(dichlorosilyl)trichlorosilylmethane, and 20 ml of dried benzene forming a mixture. The mixture was brought to reflux and acetylene gas was blown into the mixture at 90 ml per minute for 4 hours. The mixture was vacuum distilled at 67 Pa to yield a mixture comprising 2.02 g of 1,1,3,3-tetrachloro-2-trichlorosilyl-1,3-disilacyclopent-4-ene (TCD-GC area 50.8%).
