Abstract:

Hypervalent iodine (III) reagents have been employed as mild oxidants in a variety of C-X bondforming reactions. However, superstoichiometric amounts of iodine (III) reagents are typically employed, thus generating equimolar amounts of undesired aryl iodides. In 2005, the Ochiai and Kita groups independently reported a catalytic process involving in situ oxidation of iodoarenes by using meta-chloroperbenzoic acid (m-CPBA). Since then, this concept has been extensively used for the synthesis of a variety of organic molecules. We herein report our preliminary results on an economical approach to benzolactones from simple benzoic acids via metal-free, aryl iodide-catalized C-O bond formation initiated by Csp2-H and Csp3-H functionalization.
