    • Abstract

       

      Cu2+ -doped zeolitic imidazolate framework-8 (ZIF-8)-catalyzed one-pot procedure to synthesize β-keto and vinyl sulfones by the direct oxysulfonylation and hydrosulfonylation of alkynes via radical reaction under mild conditions has been described. The advantages of this protocol included broad substrate scope and excellent β-keto and E-stereoselectivity. The Cu/ZIF-8 catalyst not only exhibited excellent performance but also had a great stability in the reaction, successfully allowing its reuse up to five cycles. This efficient Cu/ZIF-8heterogeneous catalyst is explored for the first time to generate β-keto and vinyl sulfones.
