A metal‐free, photochemical strategy for the direct alkylation of indoles was developed. The reaction, which occurs at ambient temperature, is driven by the photochemical activity of electron donor–acceptor (EDA) complexes, generated upon association of substituted 1H‐indoles with electron‐accepting benzyl and phenacyl bromides. Significant mechanistic insights are provided by the X‐ray single‐crystal
已开发出一种用于吲哚直接烷基化的无金属光化学方法。该反应在环境温度下发生,受电子给体-受体(EDA)配合物的光化学活性驱动,该配合物是由取代的1H-吲哚与电子接受性苄基和苯甲酰溴缔合而产生的。对与光烷基化有关的EDA配合物进行X射线单晶分析,并确定该过程的量子产率(Φ),可提供重要的机械学见解。
