The sodium periodate mediated oxidative cleavage of the C-C bond of twelve epoxides is reported with yields of the corresponding carbonyl compounds in up to 91%. This is a two-step reaction that proceeds through a rate-limiting epoxide opening to a vicinal diol that is cleaved in situ to the corresponding carbonyl compound. This method serves as a chemoselective alternative to ozonolysis.
据报道,高碘酸钠介导的十二种环氧化合物的碳 - 碳键氧化裂解反应,相应羰基化合物的产率高达91%。这是一个两步反应,首先通过限速的环氧化物开环生成邻二醇,然后邻二醇原位裂解为相应的羰基化合物。该方法可作为臭氧分解的化学选择性替代方法。
