Taming the carbamoyl radical for selective hydrocarbamidation of alkynes via metallaphotoredox catalysis
The direct addition of an amide group across unsaturated C–C bonds remains a persistent challenge in chemical transformations. Although nickel-catalyzed hydrocarbamoylation and hydroamidation reactions of alkynes have been developed under thermal conditions, these protocols typically require formamide and isocyanate as...
