Ozonolysis is an important organic chemistry transformation, widely employed for the synthesis of carbonyl compounds. However, handling difficulties associated with ozone makes this a dangerous and tedious task to perform on a large scale. Herein, we report a continuous photo-flow protocol for the anaerobic oxidative cleavage of styrenes using nitroarene as the oxygen transfer reagent. The developed flow process provided yields up to 80% in a shorter residence time of 60–90 minutes. Various styrene derivatives underwent anaerobic cleavage, leading to the formation of carbonyl derivatives. This developed photo-flow process carries significant potential for the industrial scale production of carbonyl compounds.

用于苯乙烯厌氧氧化裂解的可扩展连续光流方案

臭氧分解是一种重要的有机化学转化，广泛用于羰基化合物的合成。然而，处理与臭氧相关的困难使得大规模执行这项任务变得危险而乏味。在此，我们报告了使用硝基芳烃作为氧转移试剂进行苯乙烯厌氧氧化裂解的连续光流方案。所开发的流程在 60-90 分钟的较短停留时间内提供高达 80% 的产率。各种苯乙烯衍生物经历厌氧裂解，导致羰基衍生物的形成。这种开发的光流工艺对于工业规模生产羰基化合物具有巨大的潜力。
