Hypervalent iodine(III) reagents in organic synthesis

This review summarizes the chemistry of hypervalent iodine(III) compounds with emphasis of their synthetic applications.The preparation and reactions of (difluoroiodo)arenes, (dichloroiodo)arenes, iodosylarenes, [bis(acyloxy)iodo]arenes, and aryliodine(III) organosulfonates are overviewed.Application of these reagents allows mild and highly selective oxidative transformations in a facile and environmentally friendly manner.Some of these useful transformations can be carried out using organoiodine(III) compounds as catalysts or recyclable reagents.
