The title compounds, 2-aryl-3-iodo-4H-1-benzopyrans and 2-alkyl-or 2-aryl-3-iodo-4H-1-benzothiopyrans, were prepared by reaction of the corresponding heterocyclic derivatives with the iodine-cerium(IV) ammonium nitrate system under mild conditions. The scope and proposed mechanism of the reaction were also demonstrated.

Abstract Reactions of the 3—iodo derivatives of flavones, thioflavones and thiochromones with finely divided copper at 200–210°C gave the title compounds respectively. Thus a new way to these compounds was provided.
