An environmentally benign protocol for the iodination of activated aromatics, such as phenols, anilines, and hydroxycoumarins, using inexpensive commercially available potassium iodide and ammonium peroxodisulfate in aqueous methanol at room temperature provides predominantly ortho-monoiodinated products. This acid-free method is compatible with various oxidizable functional groups.
