C–H functionalization of indoles. The reaction affords 2,3-difunctionalized indoles in up to 84% yield, but the reaction rate depends strongly on electronic substituent effects. Mechanistic DFT studies and control experiments suggest that the secondary functionalization occurs through an independent photocatalytic oxidation of bromide ions formed during the reaction to generate molecular bromine capable
本文公开了一种新型的吲哚的可见光光催化双 C-H 功能化。该反应以高达 84% 的产率提供 2,3-双官能化吲哚,但反应速率很大程度上取决于电子取代基的影响。机械 DFT 研究和控制实验表明,二次官能化是通过对反应过程中形成的溴离子进行独立的光催化氧化而发生的,以生成能够亲电 C-3 溴化的分子溴。
