Photolysis of pentamethylphenyldisilane in the presence of t-butyl alcohol gave a mixture of adducts which were readily oxidized to 1-(t-butoxydimethylsilyl)-2-(trimethylsilyl)benzene by oxygen. Photolysis of p-tolylpentamethyldisilane in the presence of t-butyl alcohol afforded -(t-butoxydimethylsilyl)-1-methyl-5-trimethylsilyl-1,3-cyclohexadien e (4) as a primary photoproduct. The uv-irradiation of 4 gave ring opened products, 2-(t-butoxydimethylsilyl)-5-methyl-1-trimethylsilyl-1,3,5-hexatriene and 2-(t-butoxydimethylsilyl)-5-methyl-3-trimethylsilyl-1,3,5-hexatriene in a ratio of 1. 8/1.
