The reactions of ketene silyl acetals and silyl enol ethers in a CCl4 solution containing no promoter under ambient temperature, reflux, or photo-irradiation conditions afforded products via the addition of a trichloromethyl group to those silyl substrates. Polyhalides other than CCl4 were subjected to photoreactions in a hexane solution, resulting in the formation of carbonyl derivatives based on
乙烯酮甲硅烷基缩醛和甲硅烷基烯醇醚在不含促进剂的 CCl4 溶液中在环境温度、回流或光照射条件下反应,通过向这些甲硅烷基底物添加三氯甲基提供产物。除 CCl4 外的多卤化物在己烷溶液中进行光反应,导致基于多卤代烷基加成的羰基衍生物的形成。
