A facile visible‐light photocatalytic conjugate addition to prepare 1,4‐dicarbonyl compounds has been developed by employing readily available aroyl chlorides as aryl radical sources. This operationally simple method shows a broad scope with regard to both aroyl chlorides and Michael acceptors. As a result, a variety of 1,4‐diketones were efficiently synthesized in moderate to good yields.

通过芳酰氯的共轭添加，可见光促进1,4-二羰基化合物的合成

通过使用容易获得的芳酰氯作为芳基自由基来源，已经开发了一种简便的可见光光催化共轭加成物，用于制备1,4-二羰基化合物。对于芳酰氯和迈克尔受体，这种操作简单的方法显示了广泛的范围。结果，有效地合成了各种1,4-二酮，收率中等至良好。
