An atom economic β-C(sp3)−H chlorination of amide derivatives has been developed. This mild protocol employs CuCl2 instead of palladium catalysts with atom-economic HCl as chlorine sources and enables the late-stage functionalization of medicine derivatives. Mechanism studies suggest a plausible visible light triggered ligand-to-metal charge transfer (LMCT)/1,4-hydrogen atom transfer (HAT) cascade.

光诱导铜电荷转移催化酰胺衍生物的 β-C(sp3)−H 氯化
已经开发出酰胺衍生物的原子经济β -C(sp 3 )−H 氯化。这种温和的方案采用 CuCl 2代替钯催化剂,并以原子经济的 HCl 作为氯源,并能够实现药物衍生物的后期功能化。机制研究表明,可见光触发配体到金属电荷转移 (LMCT)/1,4-氢原子转移 (HAT) 级联是合理的。
