an aryl group with a silyl tethered alkene yields a tetracyclic 2-silaoxane with high regiose-lectivity. The multicyclic structure has been further modified to give an unstable tricyclic diol. Photocycloaddition between cyclopentene and phenylcyclopropane gave a single major cycloadduct without cyclopropyl ring opening, indicating that the putative radical intermediate involved in cycloaddition apparently
用甲硅烷基系链的烯烃辐照芳基产生具有高区域选择性的四环2-硅氧烷。多环结构已被进一步修饰以得到不稳定的三环二醇。环戊烯和苯基环丙烷之间的光环加成反应生成了一个没有环丙基开环的主要环加合物,这表明参与环加成反应的假定自由基中间体如果存在则寿命很短。
