| Abstract: | The coupling of aryldiazonium tetrafluoroborates, DABCO?(SO2)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. |
