Sulfonamides are among the most important chemical motifs in pharmaceuticals and agrochemicals. However, there is no methodology to directly introduce the sulfonamide group to a non‐prefunctionalized aromatic compound. Herein, we present the first dehydrogenative electrochemicalsulfonamidesynthesis protocol by exploiting the inherent reactivity of (hetero)arenes in a highly convergent reaction with

The palladium‐catalysed dehydrogenation of sp3 carbon‐hydrogen bonds of N‐alkylbenzenesulfonamides allows a simple access to N‐alkenylbenzenesulfonamides. The reaction proceeds with easily accessible catalysts, with pivalate as a base, and allows a variety of substituents both on nitrogen and on the arene moiety.
