Excitation of photoactive electrondonor–acceptor (EDA) complexes is an effective way to generate radicals. Applications in a catalytic regime typically use catalytic donors. Herein, we report that readily available electron-poor tetrachlorophthalimides can act as effective organocatalytic acceptors to trigger the formation of EDA complexes with a variety of radical precursors not amenable to previous

readily available aldehydes, primary amines and 4-alkyl-1,4-dihydropyridines (alkyl-DHPs) for the synthesis of secondary amines at room temperature under visible light irradiation has been accomplished. This transformation occurs smoothly under mild conditions to enable facile access to various secondary amines with high efficiency, wide substrate scope and good functional group tolerance, and can be
