(I) has been investigated. Unlike thermolysis of I, which produces tetramethyldisilene as intermediate, irradiation at 10 K in an argon matrix or 77 K in a 3-methylpentane glass led to a di-π-methane photorearrangement to give 3,4-benzo-6,7-disila-6,6,7,7-tetramethylbicyclo [3.3.0.02,8]. octane. Photolysis of I at room temperature in cyclohexane did, however, give tetramethyldisilene.
研究了5,6-苯并-2,2,3,3-四甲基(2,3-二硅双环[2.2.2。] octa-5,7-二烯)(I)的光化学。与I的热分解不同,后者会产生四甲基二ilene作为中间体,在氩气基质中以10 K辐射,在3-甲基戊烷玻璃中以77 K辐射会导致二-π-甲烷光重排,从而生成3,4-苯并-6,7-二硅-6,6,7,7-四甲基双环[3.3.0.0 2,8 ]。辛烷。然而,室温下I在环己烷中的光解确实产生了四甲基二ilene。
