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–H thianthrenation of aromatics, this method provides a new tool for the site-selective fluorosulfonylation of drugs.
