Benzene, halobenzenes, and a number of more or less deactivated arenes,including nitrobenzene, readily reacted in anhydrous HIO3/AcOH/Ac2O/conc. H2SO4 mixtures to probably give ArIO2 intermediates or other hypervalent species (not isolated). The final reaction mixtures were poured into excess aq. Na2SO3
