Procedure

Hydrosilation of diphenylacetylene with bis(dichlorosilyl)methane in the presence of Pt((CH2 =CHSiMe2)2O)2. Into the same apparatus as described in Example 1 were added 1 g of bis(dichlorosilyl)methane, 0.84 g of diphenylacetylene, 20 μl of Pt((CH2 =CHSiMe2)2O)2 in 1,1,3,3-tetramethyl-1,3-divinyl-1,3-disiloxane (4 weight percent Pt), and 20 ml of dried benzene. The flask content was refluxed, with stirring, for 4 hours and then the solvent removed at atmospheric presssure. The products were distilled at 67 Pa to give a mixture comprising 0.73 g of 1,1,3,3-tetrachloro-4,5-diphenyl-1,3-disilacyclopentane (TCD-GC area 73.7%) and 3,3,5,5-tetrachloro-1,2,6,7-tetraphenyl-3,5-disilahepta-1,6-diene (TCD-GC area 13.2%).
