An alkene and a (hetero)arene, to be reduced or retained? In contrast to conventional processes, in the reported hydrogen atom transfer (HAT) protocol enabled by energy transfer (EnT) catalysis, the benzenoid ring of a quinoline is more easily reduced than an electron-deficient alkene. Furthermore, many reducing labile moieties, such as aryl iodides, electron-deficient alkynes, benzsulfamides, and
