The photolysis of tris(trimethylsilyl)phenylsilane (I) in the presence of allyl chloride, allyl bromide, 2-cyclohexenyl chloride, 2-cyclohexenyl bromide and 2-methylallyl chloride resulted in formation of the respective 1-(2-alkenyl)-1-halo-1-phenyltrimethyldisilanes in moderate yields.Irradiation of I in the presence of crotyl chloride, 1-methylallyl chloride, prenyl chloride and 1,1-dimethylallyl chloride afforded the corresponding α- and γ-substituted chlorodisilanes.Photolysis of I in the presence of allyl ethyl ether produced 1-phenyl-1-trimethylsilyl-2-ethoxymethyl-1-silacyclopropane, although this product was not isolated.The reaction of this silacyclopropane with hydrogen chloride, methanol and boron trifluoride etherate is described.
