Sulfonylfluorides are valuable synthetic motifs for a variety of applications, among which sulfur(VI) fluoride exchange-based “click chemistry” is currently the most prominent. Consequently, the development of novel and efficient synthetic methods to access these functional groups is of great interest. Herein, we report a mild and environmentally benign electrochemical approach to prepare sulfonyl

types of aliphaticsulfonylhalides (Cl versus F) were compared in parallel synthesis of sulfonamides derived fromaliphatic amines. Aliphaticsulfonyl fluorides showed good results with amines bearing an additional functionality, while the corresponding chlorides failed. Both sulfonylhalides were effective in the reactions with amines having an easily accessible amino group. Aliphaticsulfonyl chlorides

A practical electrochemically driven method for fluorosulfonylation of both aryl and alkyl thianthrenium salts has been disclosed. The strategy does not need external redox reagents or metal catalysts. In combination with C–Hthianthrenation of aromatics, this method provides a new tool for the site-selective fluorosulfonylation of drugs.
