Reaction of alkynes with ICI and an iodide source results in the stereoselective formation of diiodoalkenes in moderate to high yield, At r.t., the reaction is stereospecific, resulting in the formation of E-diiodoalkenes, however lowering the temperature and using a more soluble iodide source results in a stereoselective formation of the Z-diiodoalkenes.

Treatment of an alkyne with iodine monochloride and sodium iodide at room temperature results in the formation of the thermodynamic (E)-diiodoalkene. The corresponding (Z)-diiodoalkene can also be produced, by treatment of the alkyne with iodine monochloride at −78 °C in the presence of tetraethylammonium iodide. Such 1,2-diiodoalkenes are useful for the synthesis of more functionalised alkenes by using either Stille or Suzuki cross-coupling protocols.
