three‐component synthesis of N‐aminosulfonamides starting from diaryliodonium salts, hydrazines and sulfurdioxide is reported. This reaction proceeds under mild conditions at room temperature and is driven by visible light. A simple bisulfite salt can be used as a readily available and easy‐to‐handle sulfurdioxide source. Mechanistic studies support a catalytic photoredox pathway with the diaryliodonium

A facile route to aryl N-aminosulfonamides under mild conditions is provided. The reaction of aromatic amines (including heteroaromatic amines), sulfurdioxide, and hydrazines proceeds efficiently with good functional group tolerance. The in situ generated diazonium ion is involved in the aminosulfonylation process.
