energy-transfer-driven homolysis followed by decarboxylation generates the persistent iminyl radical and aryl radical, which would undergo an unprecedented intermolecular hydrogenatomabstractionfrom the alkyl substrate to provide the key C(sp3) radical. Selective radical–radical C–N cross-coupling furnishes imines which are valuable amine building blocks.
