Hypervalent iodine(III) reagents show promising properties in organic synthesis, however, the application of nitrooxyl (O2NO)-containing I(III) reagents remains underexplored. Here, the authors report the synthesis of a benziodazole-type O2NO-I(III) reagent, which can be applied to the synthesis of furazan heterocycles as a nitrating agent, by reaction with β-monosubstituted enamines via a copper-catalyzed radical nitration/cyclization/dehydration cascade.
