nickel-catalyzed aminocarbonylation of (hetero)aryl bromides was developed. The utilization of readily available oxamic acids, the application of a broadly used organic photoredox catalyst (4CzIPN), and mild reaction conditions make this transformation an appealing alternative to classical amidation procedures. The generation of carbamoyl radicals was supported by trapping reactions with a hydrogen
开发了一种用于(杂)芳基溴的光氧化还原和镍催化氨基羰基化的有效方法。利用容易获得的草酸、广泛使用的有机光氧化还原催化剂 (4CzIPN) 和温和的反应条件,使这种转化成为经典酰胺化程序的有吸引力的替代方案。在 D 2 O 存在下,通过与氢原子转移催化剂的捕获反应支持氨基甲酰基自由基的产生,产生氘代甲酰胺。对于各种草酸,证实了该氘化方案的通用性。
