Procedure

Hydrosilation of diphenylacetylene with bis(dichlorosilyl)trichlorosilylmethane in the presence of Pt(C2H4)(PPh3)2. Into the same apparatus as described in Example 1 were added 0.99 g of bis(dichlorosilyl)trichlorosilylmethane, 0.102 g of Pt(C2H4)(PPh3)2, and 25 ml of dried benzene to form a mixture. To this mixture at reflux was added 0.52 g of diphenylacetylene in 10 ml of benzene over a 30 minute period. The resulting mixture was stirred for an additional 18 hours and then the solvent remove at atmospheric pressure. The residue was vacuum distilled at 67 Pa to yield a mixture comprising 0.61 g of 1,1,3,3-tetrachloro-2-trichlorosilyl-4,5-diphenyl-1,3-disilacyclopentane (TCD-GC area 13.8%).
