A mild and eco-friendly visible-light-induced decarboxylative acylation of quinoxalin-2(1H)-ones and α-oxo carboxylic acids with ambient air as the sole oxidant at room temperature was established. The reaction proceeded efficiently without any metal catalysts, strong oxidants or external-photosensitizers, ultimately reducing the generation of waste.
建立了在室温下以环境空气为唯一氧化剂的轻度和生态友好型可见光诱导的喹喔啉-2(1 H)-ones和α-氧代羧酸的脱羧酰化反应。该反应无需任何金属催化剂,强氧化剂或外部光敏剂即可有效地进行,最终减少了废物的产生。
