Recent advances in the development of polymer-supported iodine(V) oxidants, recyclable monomeric hypervalent iodine(III) reagents and catalytic systems based on hypervalent iodine compounds are discussed. These efficient and environmentally friendly reagents and catalysts are particularly useful for oxidative transformations of alcohols to carbonyl compounds and for oxidations at the benzylic position.

A simple three-step preparation of polymer-supported N-(2-iodyl-phenyl)-acylamide (NIPA resin) starting from 2-iodoaniline is described. The resin was obtained with good loading levels (0.7-0.8 mmol g(-1)) and has been successfully used for efficient oxidation of a diverse collection of alcohols. Thus, treating alcohols with 1.0 equiv of the resin in 1,2-dichloroethane under reflux for 30-60 min allowed rapid and in most cases complete conversion to the corresponding carbonyl compound.
