A visible‐light‐catalyzed radical N‐acylation of amines with carboxylic acids was achieved by means of eosin Y as the photocatalyst under aqueous medium without any transition‐metal‐based catalytic systems. The new method takes advantages of visible‐light photocatalysis to generate the amides under mild conditions. A variety of amides have been synthesized in good to excellent yields. Moreover, the strategy was successfully applied in the preparation of paracetamol.

无过渡金属，可见光和轻度介导的N-酰化：水中酰胺的有效途径

曙红Y作为光催化剂，在水性介质下无需任何基于过渡金属的催化体系，即可实现胺与羧酸的可见光催化自由基N-酰化反应。新方法利用了可见光光催化在温和条件下生成酰胺的优势。已经以良好至优异的产率合成了多种酰胺。此外，该策略已成功应用于扑热息痛的制备中。
