A straightforward method for the dehydrogenative alkylation of quinoxalin-2(1)-ones with alkylbenzenes has been developed, facilitated by a photoexcited nitroarene. The reaction's success hinges on the dual role of the photoexcited nitroarene molecule, acting as both a hydrogen atom transfer (HAT) reagent and an oxidant. This technique is both atom-economical and cost-effective, due to the readily available nitroarene, which serves as the sole intermediary in the reaction process.
已开发出一种用烷基苯对喹喔啉-2(1)-酮进行脱氢烷基化的直接方法，该方法由光激发的硝基芳烃促进。该反应的成功取决于光激发的硝基芳烃分子的双重作用，它既作为氢原子转移（HAT）试剂又作为氧化剂。由于反应过程中用作唯一中间体的硝基芳烃易于获得，该技术具有原子经济性且成本效益高。
