Eco-friendly and Green Procedure for Iodination of Reactive Aromatics Using PEG 400-I2/HIO3 Combination

Abstract

Background: Iodination of organic substrate is an important reaction for synthesis of pharmacological active molecules. Methods: In view of these concerns, we reported the convenient procedure for synthesis of iodo compounds using iodine and iodic acid in PEG-400.We have reported the eco-friendly procedure for preparation of aromatic iodo compounds using iodine and iodic acid in green reaction media as polyethylene glycol (PEG-400). Results: The iodination of some aromatic compounds such as benzaldehydes, acetophenones, phenols, amines and heterocyclic compounds carried out using iodine, iodic acid and PEG-400. The synthesized substituted aromatic iodo compounds were confirmed based on spectral characterization and mixed melting points. Conclusion: The method comprises several advantages such as simple reaction procedure, easy isolation, quantitative yields, and purity of iodo products.
