ozone oxidation of silylalkenes is a highly efficient reaction to provide synthetically versatile α-silylperoxy carbonyl compounds. To gain insight into the reaction mechanism, we performed a computational study, which revealed that the reaction proceeds via [1,2]-Brook rearrangement-type silyl migration of primary ozonide. In sharp contrast to the addition-type reactions, the ozone oxidation of α-alkoxysilylalkenes
甲硅烷基烯烃的加成型臭氧氧化是一种高效反应,可提供合成上通用的α-甲硅烷基过氧羰基化合物。为了深入了解反应机理,我们进行了计算研究,结果表明反应是通过一次臭氧化物的[1,2]-布鲁克重排型甲硅烷基迁移进行的。与加成型反应形成鲜明对比的是,α-烷氧基甲硅烷基烯烃的臭氧氧化以裂解型方式进行,从而在1,2-甲硅烷基迁移之前通过伯恶臭化合物的1,3-环消除反应提供了优异的甲硅烷羧酸酯收率。 。
