(E)-Alkenyl halides were transformed into (E)-alkenyl sulfides by the nickel(0) triethyl phosphite complex-catalyzed reaction with thiols, whereas (Z)-alkenyl halides gave alkynes under the same reaction conditions. Aryl halides were also transformed into aryl sulfides using the same reagent system.

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.
