Description and 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.
