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 4-(t-butoxydimethylsilyl)-1-methyl-5-trimethylsilyl-1,3-cyclohexadiene (4) as a primary photoproduct. The UV-irradiation
在叔丁醇存在下,五甲基苯基乙硅烷的光解得到加合物混合物,该混合物很容易被氧气氧化为 1-(叔丁氧基二甲基甲硅烷基)-2-(三甲基甲硅烷基)苯。在叔丁醇存在下对甲苯基五甲基乙硅烷进行光解得到 4-(叔丁氧基二甲基甲硅烷基)-1-甲基-5-三甲基甲硅烷基-1,3-环己二烯 (4) 作为主要的光产物。4 的紫外线照射得到开环产物,2-(叔丁氧基二甲基甲硅烷基)-5-甲基-1-三甲基甲硅烷基-1,3,5-己三烯和2-(叔丁氧基二甲基甲硅烷基)-5-甲基-3-三甲基甲硅烷基-1,3,5-己三烯的比例为 1.8/1。
