Reaction of the liner poly[styrene(iodoso diacetate)] with p-toluenesulfonic acid afforded the poly[4-hydroxy(tosyloxy)iodo]styrene. This hypervalent iodine agent represented enough reactivity for the α-tosyloxylation of esters; moreover, it can be regenerated and reused as environmentally benign reagent.
