摘要：

A mild and eco-friendly visible-light-induced decarboxylative acylation of quinoxalin-2(1H)-ones and alpha-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.
