Electrochemical meta-C–H sulfonylation of pyridines with nucleophilic sulfinates

Posted in chemistry

Direct meta-selective C–H functionalization of pyridines is of paramount importance, but such reactions remain limited and highly challenging. Here, the authors report an electrochemical methodology in which nucleophilic sulfinates allow meta-sulfonylation of pyridines through a redox-neutral dearomatization-rearomatization strategy.
