A cascade reaction of cyclopropyl alcohols, DABSO (1,4-diazoniabicyclo[2.2.2]octane-1,4-disulfinate), and N-(sulfonyl)acrylamides has been developed. This tandem process went through a cyclopropanol ring opening Michael addition sequence. The γ-keto sulfinate generated from the between serves as nucleophilic reagent, N-(sulfonyl)acrylamide is used acceptor. By utilizing this strategy, multitudinous sulfone-bridged 1,7-dicarbonyl compounds that contain both β-sulfonyl amide unit sulfone skeleton were conveniently synthesized.

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.

Abstract A mild photoredox catalyzed construction of sulfides, disulfides, selenides, sulfoxides and sulfones from unstrained ketone precursors is introduced. Combination this deacylative process with S N 2 or coupling reactions provides novel convenient modular strategies toward unsymmetrical symmetric disulfides. Reactivity studies favor a bromine radical that initiates HAT (Hydrogen Atom Transfer) the aminal intermediate resulting in expulsion C‐centered intercepted to make C−S C−Se bonds. Gram scale reactions, broad substrate scope tolerance towards various functional groups render method appealing for future applications synthesis organosulfur selenium complexes.
