The reaction of o-nitroiodobenzene and mCPBA in AcOH was found to afford a novel hypervalent iodine compound which both iodine(iii) and iodine(v) moieties coexist. This new reagent is proved to be effective in realizing the synthesis of 2H-azirines.

This manuscript describes a highly enantioselective oxidative cyclization of N-Allyl Benzamides and derivatives thereof. This method uses a chiral triazole-based iodine catalyst to generate a hypervalent iodine compound in situ as the active catalytic species. Besides oxazolines, other N-heterocylces such as thiazolines, imidazolines as well as oxanines can be generated in high optical purities. <br>

An oxidative 3-amination of indole derivatives using hypervalent iodine(III) and bissulfonimides, which proceeds via the formation of indolyl(aryl)iodonium imides, was developed. This reaction was followed by an indole-selective copper-catalyzed oxidative C–N coupling reaction to obtain 3-amino indole derivatives as single regioisomers. o-Alkoxy(diacetoxyiodo)arenes showed higher reactivity in the reaction than o-alkyl(diacetoxyiodo)arenes, efficiently promoting the formation of indolyl(aryl)iodonium imides in the first step.
