We were also intended to performed a literature-known rearrangement of Nsulfonamide-based acyclic iodonium salts. Here, in case of cyclic diaryliodazinium species, the rearrangement product 21a was obtained in only 27% yield, while the Mssubstituted derivate 21b could not be observed. To verify the reactivity, the mesityl sulfonamide 2k gave a significant increase in product formation due to the prevention of side reactions yielding 21c in 56%.
