In this study, we present a photochemical method for the amination of phenols (C–H) and halophenols (SNAr), facilitated by dual catalytic pathways involving both Ir(III) photocatalysis and phenol–pyridinium electron donor–acceptor complexation. By incorporating a pyridinium additive, we achieved efficient C–N coupling between phenols and diverse aromatic nitrogen nucleophiles, delivering high yields
