Catalytic Version of and Reuse in Hypervalent Organo‐λ³‐ and ‐λ⁵‐iodane Oxidation

Abstract

Abstract Hypervalent organoiodanes are one of the most valuable classes of oxidants for use in oxidative transformations of various kinds of functionalities in modern organic synthesis. This microreview provides an overview of the recently developed aryl iodide‐catalyzed oxidations, in which hypervalent organoiodanes(III and V) generated in situ serve as the actual oxidants. We also summarize recent attempts to improve the efficiency of recyclable hypervalent organoiodanes in oxidations, updating Togo's and Sakuratani's 2002 review.(© Wiley‐VCH Verlag GmbH & Co.
