| | 1,2-DIIODOETHANE Usage And Synthesis |
| Chemical Properties | dark brown crystals | | 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.
| | Uses | 1,2-Diiodoethane is used as C-X bond formation reagent. It is also used as Pharmaceutical intermediates. | | 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.] |
