An organophotoredox 1,6-radical addition of 3,4-dihidroquinoxalin-2-ones to -quinone methides catalyzed by Fukuzumi's photocatalyst is described under the irradiation of a HP Single LED (455 nm). The corresponding 1,1-diaryl compounds bearing a dihydroquinoxalin-2-one moiety (20 examples) are obtained with good to excellent yields under mild reaction conditions. Several experiments have been carried out in order to propose a reaction mechanism.
描述了在Fukuzumi光催化剂催化下，3,4-二氢喹喔啉-2-酮与醌甲基化物进行的有机光氧化还原1,6-自由基加成反应，该反应在HP单颗LED（455 nm）照射下进行。在温和的反应条件下，以良好至优异的产率得到了相应的带有二氢喹喔啉-2-酮部分的1,1-二芳基化合物（20个实例）。为了提出反应机理，进行了几项实验。
