activate iodine in the addition reaction with triple bonds. A facile and technologically straightforward procedure was developed for the synthesis of E‐diiodoalkenes based on the reaction of alkynes with an I2–H2O2 system in THF. Selective iodination of terminal and internal alkynes containing electron‐donating and electron‐withdrawing substituents afforded 16 E‐diiodoalkenes in yields up to 89%.

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.

A mild and selective palladium-catalyzed carbonylation of (E)-1,2-diiodoalkenes protocol for the synthesis of (E)-3-iodoacrylate esters and maleic diesters has been developed. In the presence of PdCI2, CuCl2, and CO, (E)-3-iodoacrylate esters and maleic diesters were obtained selectively in moderate yields. Noteworthysis that a clean inversion of configuration takes place in the palladium-catalyzed dicarbonylation of (E)-1,2-diiodoalkenes procedure.

A new approach to the stereospecific diiodination of alkynes under mild conditions has been developed. This protocol employs ammonium persulfate as an oxidant and iodide as an iodine source, and provides a highly efficient and general method for the preparation of a broad range of (E)-diiodoalkenes in water.
