Comprehensive Summary Herein, we report a rare example of three‐component net‐oxidative sulfonylation SO 2 surrogate with an oxidatively activated radical precursor under mild and metal‐ external‐oxidant‐free conditions. The mildness sustainability the reaction are enabled by photoelectrocatalysis, 3‐aza‐1,5‐dienes, organotrifluoroborates 1,4‐diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO) undergo sulfonylative cyclization to afford sulfono 4‐pyrrolin‐2‐ones in atom‐economical manner broad substrate scope good functional‐group tolerance. protocol is amenable late‐stage diversification complex molecular architectures as well gram‐scale synthesis. Sunlight could be used light source, conducted all‐solar mode using commercially available photovoltaic panel generate electricity situ . Mechanistic studies reveal that generated (DABCO), which was generally innocent previous reactions, functions electron shuttle between photocatalytic cycle reactants.
