Abstract
AbstractAn efficient, green, and oxidant‐free electrochemical method for alkyne difunctionalization was described. Using undivided electrochemical cell for iodosulfonylation of alkynes with commercially available iodide radical (NaI), arylsulfonyl radical (ArSO2NHNH2) sources, a variety of (E)‐β‐iodovinyl sulfones were obtained in one‐pot with wide substrate scope, excellent regio‐ and stereoselectivity under mild and ecofriendly conditions.
