在此,我们报告了光激发硝基芳烃促进醇、胺、醛和亚胺厌氧氧化的方案。机理研究支持光激发硝基芳烃与醇和胺经历双氢原子转移(HAT)步骤以提供各自的酮和亚胺产物的观点。在醛和亚胺存在的情况下,连续发生 HAT 和氧原子转移 (OAT) 事件,分别产生羧酸和酰胺。这种转变适用于连续光流设置,从而缩短了反应时间。

A Ru2+-photocatalyzed, visible-light-mediated ATRA reaction for the straightforward preparation of 1,4-ketoaldehydes, 1,4-diketones, and 1,4-ketoesters, which are of difficult access by other means, is reported herein. This method employs readily accessible α-bromoketones and alkyl vinyl ethers as starting materials, allowing the construction of secondary, tertiary, and challenging quaternary centers
