A copper-catalyzed addition of halide and sulfide groups to internal alkynes was carried out using disulfides with N-Bu 4 NX (X = Br, I or Cl) in air. The present reaction can selectively prepare the corresponding ANTI-configured haloalkenyl sulfide, and uses both sulfide groups of the disulfide reagent.

Shuttle catalysis is emerging as a potent strategy to unleash unprecedented synthetic flexibility in organic synthesis. Herein, we disclose a rare example of shuttle hetero-difunctionalization to transfer two distinct functional groups between β-halosulfides and alkynes with excellent chemo-, regio-, and stereoselectivity via a paired electrolysis process. This unfolds new opportunities for selective
