A convenient and simple one-pot method for the preparation of iodoarenes at room temperature has been developed, by sequential diazotization-iodination of aromatic amines with NaNO2/KI in the presence of a sulfonic acid based cation-exchange resin in water. This inexpensive, noncorrosive and eco-friendly synthetic route is general in nature and allows for the preparation of iodoarenes with an electron-donating or -withdrawing group in various positions from the corresponding amines in 50-98% yields.
