An Efficient and Selective Method for the Preparation of Iodophenols

Article abstract of DOI:10.1021/jo00305a026

Direct iodination of a wide range of phenols may be achieved with unprecedented selectivity in aqueous alcohol solvents by the action of a reagent preparated in situ from sodium hypochlorite and sodium iodide.Para-substituted phenols (or ortho-substituted, when the para-position is already occupied) are obtained in fair to excellent yields by simple isolation techniques.The extent of iodination is easily controlled by stoichiometry.The technique is also useful with some anilines.
