The coupling of aryldiazonium tetrafluoroborates, DABCO⋅(SO 2 ) 2 , and hydrazines under metal‐free conditions leads to the formation of aryl N ‐aminosulfonamides. The reaction proceeds smoothly at room temperature and shows broad functional‐group tolerance. A radical process is proposed for this transformation.
