However, most of these methods require hazardous or toxic reagents or high reaction temperature for a long reaction time. A combination of N-iodosuccinimide and trifluoromethane sulfonic acid (2–5 equiv.) 12 has been used for the iodination of deactivated aromatics compounds. Iodination of activated aromatic ethers with only N-iodosuccinimide in acetonitrile has been reported more recently. 7 Nevertheless long reaction times (6–24 h) and high reaction temperature ...
