In contrast to traditional ground-state palladium catalyzed alkyl Heck reactions, which are thermodynamically unfavourable and endothermic, excited-state palladium catalysis facilitates single-electron mechanisms, with light primarily driving the formation of alkyl radicals from triplet-state Pd(0). Here, we report a novel and mechanistically distinct Pd-catalyzed reaction, where the key hybrid alkyl Pd(I)-radical intermediate is generated from the triplet-state Pd(II) at room temperature.
