Procedure

Hydrosilation of phenylacetylene with bis(dichlorosilyl)trichlorosilylmethane in the presence of Pt(C2H4)(PPh3)2. Into the same apparatus as described in Example 1 were add 0.99 g of bis(dichlorosilyl)trichlorosilylmethane, 0.101 g of Pt(C2H4)(PPh3)2, and 25 ml of dried benzene forming a mixture. To this mixture at reflux was added 0.32 ml of phenylacetylene over a 10 minute period. The resulting mixture was stirred for an additional 15 hours at reflux temperature and then the solvent removed. The residue was vacuum distilled at 67 Pa to give a mixture comprising 0.58 g of 1,1,3,3-tetrachloro-2-trichlorosilyl-4-phenyl-1,3-disilacyclopent-4-ene (TCD-GC area 43.9%).
