A straightforward multicomponent sulfonamidation of nitroarenes, sodium metabisulfite and boronic acids was established under transition‐metal‐free conditions to access diverse sulfonamides from readily available and low‐cost materials modularly. Inorganic salt sodium metabisulfite not only served as a sulfur dioxide source, but also played a key role for both activator and reductant during sulfonamidation
