Hydrosilation of phenylacetylene with bis(dichlorosilyl)methane in the presence of H2PtCl6 /THF. Into the same apparatus as described in Example 1 were added 1 g of bis(dichlorosilyl)methane, 20 μl of 0.1 M H2PtCl6 in THF (tetrahydrofuran) solution, and 20 ml of dried benzene. The flask content was heated to reflux and 0.52 ml of phenylacetylene was added over a ten minute period. The flask content was refluxed, with stirring, for another 8 hours and then the solvent removed at atmospheric pressure. The products were vacuum distilled at 67 Pa to give a mixture comprising 1.66 g of 3,3,5,5-tetrachloro-1-phenyl-3,5-disilapenta-1-ene (TCD-GC area 27.3%) and 3,3,5,5-tetrachloro-1,7-diphenyl-3,5-disilahepta-1,6-diene (TCD-GC area 26.4%).
