Iodination of o-nitrotoluene in H2SO4 or CF3SO3H at 0°C with compounds having a nitrogen-iodine bond leads to the formation of isomeric mono- and diiodo derivatives whose ratio differs from the statistical value. The reaction of nitrobenzene with 2

Dissolution of N-iodosuccinimide in sulfuric acid gives rise to electrophilic iodine-containing species which are capable of successfully iodinating aromatic compounds with electron-withdrawing substituents in the temperature range from 0 to 20°C. T
