Successive treatment of aromatic amines with liquid nitrogen dioxide and powdered sodium iodide in acetonitrile at -20 °C, followed by usual work- up, gave the corresponding aryl iodides in good yield. This method worked especially well for less basic amines bearing electron-withdrawing substituents.
