Ru complexes, the discovery and employment of photocatalysts based on alternative and abundant metal salts remain highly necessary. Herein, the visible-light-induced decarboxylative alkylation of quinoxalin-2(1H)-ones with phenyliodine(III) dicarboxylate has been accomplished using inexpensive and catalytic amount of CeCl3 as the photocatalyst. The novel protocol has advantages of mild conditions,
尽管在使用有机
染料或昂贵的 Ir 和 Ru 配合物的光氧化还原催化方面取得了进展,但基于替代和丰富的
金属盐的光催化剂的发现和应用仍然非常必要。在此,使用廉价且催化量的CeCl 3作为光催化剂,已经完成了
喹喔啉-2(1 H )-酮与苯
碘(III)二
羧酸盐的可见光诱导的脱羧烷基化反应。该新方案具有条件温和、产率高、底物范围好等优点。对照实验表明,一种激进的机制是造成目前转变的原因。
