A metal-free reusable hypervalent iodine(III) reagent is employed as a stable catalyst for the selective oxidation of active methylenes, indoles and styrene C-H bond to corresponding carbonyl compounds. From both economic and environmental point of view use of 2-Iodosobenzoic acid for oxidations replacing metals, makes the reaction interesting.
