Iodine(iii) and iodine(v) coexist in new nitroiodoxybenzene-based oxidant

Chemists have made the first hypervalent iodine compound containing both iodine(iii) and iodine(v). The new oxidant has proved effective in making 2-unsubstituted 2H -azirines from enamines, a synthesis not possible using existing hypervalent iodine reagents.
