Hypervalent Iodine Reagents and Green Chemistry

Recent advances in the development of environmentally friendly recyclable reagents and catalytic systems based on hypervalent iodine are discussed. The review covers the following topics of active current research: polymer-supported iodine(III) and iodine(V) oxidants, recyclable monomeric hypervalent iodine(III) reagents, reactions of hypervalent iodine in solid state, application of water or recyclable organic solvents in these reactions, and catalytic systems based on hypervalent iodine compounds. These efficient and ecofriendly reagents and catalytic systems are now widely used in organic synthesis for various oxidative transformations of organic substrates.
