An electrochemical sulfonylation of alkynes with sodium sulfinates was achieved for the first time at room temperature. Employing this electrolysis strategy, reaction occurs efficiently under transition-metal-free, external oxidant-free, and base-free conditions furnishes diverse alkynyl sulfones in satisfactory yield broad functional group tolerance.
