A highly selective, environmentally friendly, and scalable electrochemical protocol for the construction of α-acyloxy sulfides, through the synergistic effect of self-assembly-induced C(sp3)–H/O–H cross-coupling, is reported. It features exceptionally broad substrate scope, high regioselectivity, gram-scale synthesis, construction of complex molecules, and applicability to a variety of nucleophiles

amide functionality play a significant role in the development of pharmaceuticals and biologically active compounds. While conventional amidation strategies primarily relies on C‐N bond formation, the strategic integration of photoredoxcatalysis for synthesizing these compounds through C‐C bond formation is in accordance with the principles of green chemistry and sustainability. Herein, we demonstrate
