Organic halides are critical building blocks that participate in various cross-coupling reactions. Furthermore, they widely exist as natural products and artificial molecules in drugs with important physiological activities. Although halogenation has been well studied, to the best of our knowledge, studies focussing on sensitive systems (e.g. aryl amines) have not been reported. Herein, we describe a compatible oxidative halogenation of (hetero)arenes with air as the oxidant and halide ions as halide sources under ambient conditions (visible light, air, aqueous system, room temperature, and normal pressure). Moreover, this protocol is practically feasible for gram-scale synthesis, showing potential for industrial application.

可见光促进（杂）芳烃的氧化卤化

有机卤化物是参与各种交叉偶联反应的重要组成部分。此外，它们作为具有重要生理活性的药物中的天然产物和人工分子广泛存在。尽管已经对卤化进行了充分的研究，但据我们所知，还没有报道过针对敏感系统（例如芳基胺）的研究。在此，我们描述了在环境条件（可见光，空气，水系统，室温和常压）下，（杂）芳烃与空气作为氧化剂和卤离子作为卤化物源的相容性氧化卤化作用。而且，该协议对于克级合成实际上是可行的，显示出工业应用的潜力。
