Polymer-supported hypervalent iodine reagents

Polymer-supported hypervalent iodine reagents, bearing (diacetoxy)iodo, (dihalo)iodo, (hydroxy)(tosyloxy)iodo, (hydroxy)(phosphoryloxy)iodo, aryliodonium, 1,2-benziodoxol-3-one, and hypervalent iodine groups as counter anions, can be used for various oxidative functional group conversions of substrates. These polymer species can be recovered quantitatively by simple filtration, and can be regenerated and reused. Thus, these polymer-supported hypervalent iodine reagents are very useful, effective, and environmentally benign reagents for organic synthesis.
