Versatile Hypervalent‐Iodine(<scp>III</scp>)‐Catalyzed Oxidations with <i>m</i>‐Chloroperbenzoic Acid as a Cooxidant

Abstract

A new and effective use of hypervalent iodine(III) reagents as catalysts involves the transformation of iodoarenes 1 into hypervalent iodine(III) species 2 with meta-chloroperbenzoic acid (mCPBA) as the appropriate cooxidant. With observed turnover numbers greater than 70, this procedure paves the way for broader application of these useful oxidants in organic synthesis.
