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
