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