A copper-catalyzed addition of halide and sulfide groups to internal alkynes was carried out using disulfides with n-BU4NX (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.
