Hydrosilation of phenylacetylene with bis(dichlorosilyl)methane in the presence of RhCl(PPh3)3. Into the same apparatus as described in Example 1 were added 0.99 g of bis(dichlorosilyl)methane, 0.102 g of RhCl(PPh3)3, and 20 ml of dried benzene. The flask content was heated to reflux and 0.52 ml of phenylacetylene was added over a 10 minute period. The flask content was refluxed, with stirring, for another 2 hours and then the solvent removed at atmospheric pressure. The products were vacuum distilled at 67 Pa to give a mixture comprising 0.9 g of 3,3,5,5-tetrachloro-1-phenyl-3,5-disilapent-1-ene (TCD-GC area 5.5%) and 3,3,5,5-tetrachloro-1,7-diphenyl-3,5-disilahepta-1,6-diene (TCD-GC area 66.5%).
