An environmentally benign protocol for the iodination of activated aromatics, such as phenols, anilines, and hydroxycoumarins, using inexpensive commercially available potassiumiodide and ammonium peroxodisulfate (1:2.5 molar equivalents per mole of substrate) in aqueous methanol (MeOH-H2O, 6:1) at room temperature has been developed. The protocol provides for ortho-selective monoiodination as the
