The diazotization of aryl amines at room temperature in paste form with NaNO(2), p-TsOH and a small amount of water, followed by treatment with KI provides a new, simple, and effective route for the preparation of various aryl iodides. The water-paste and strong acid-free reaction conditions are environmentally friendly and compatible with acid-sensitive functional groups. (c) 2007 Elsevier Ltd. All rights reserved.
