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.
