1,2-DIIODOETHANE Chemical Properties,Uses,Production

Chemical Properties

dark brown crystals

Uses

1,2-Diiodoethane is used as C-X bond formation reagent. It is also used as Pharmaceutical intermediates.

Uses

1,2-Diiodoethane can be used:

  • To synthesize samarium(II) iodide-water complex (SmI2-H2O complex), a single-electron transfer reagent, to further synthesize 3-hydroxy carboxylic acids.
  • To synthesize derivatives of regioselective homopropargyl alcohols by using sonochemical Barbier-type reaction conditions.
  • As an iodine source and an effective reagent for the dehydroxy-iodination of alcohols.

Purification Methods

Dissolve it in ether, wash it with saturated aqueous Na2S2O3, dry over MgSO4 and evaporate the ether in vacuo and distil it. Store it in the dark. [Molander et al. J Am Chem Soc 109 453 1987]. [Beilstein 1 IV 169.]
