Abstract: Treatment of various aromatic compounds with 1-(p-toluenesulfonyloxy)-1, 2- benziodoxol-3 (1H)-one 1A and iodine gave the corresponding iodinated compounds in good yields. Similarly, chlorination and bromination proceeded effectively. As compared with other trivalent iodine compounds, the iodinane 1A showed the best reactivity as a halogenation reagent.
