Abstract
New methodolgy for direct iodination of benzenoid compounds has been d eveloped; the aromatic substrate is simply mixed with iodine and sulfu ric acid, suspended in an inert medium, such as 1,1,2-trichlorotrifluo roethane (CF2ClCFCl2) or perfluorocarbon, and elemental fluorine is pa ssed through the system at room temperature, High conversions to iodoa rormatic products occur, even with some deactivated systems, e.g. nitr obenzene. A very powerful brominating system is produced using the ana lagous methodology.
