Herein, a photoinitiated radical relay reaction of quinoxalin-2(1H)-ones, with acyloxy nitroso compounds as a source of radicals, is described. Although the C–H functionalization of quinoxalin-2(1H)-ones has been investigated, its difunctionalization, the simultaneous construction of C–C and N–N bonds directly via the radical relay reaction, has rarely been reported. Moreover, the obtained products

硝基化合物为自由基源的quinoxalin-2(1 H )-ones的光引发自由基中继反应。尽管已经研究了quinoxalin-2(1 H )-ones的C-H官能化,但很少报道其双官能化,即直接通过自由基中继反应同时构建C-C和N-N键。此外,所获得的产物在温和条件下经历了顺序反应以获得
喹喔啉-2(1 H )-酮的C7-NO 2 。
