Poly[4-hydroxy(tosyloxy)iodo]styrene (high M. W.) and poly{α-methyl[4-hydroxy(tosyloxy)iodo]styrene} (low M. W.) were prepared from polystyrene (average M. W. = 45,000) and poly(α-methylstyrene) (average M. W. = 6,200), respectively, and their reactivities for the α-tosyloxylation of ketones and oxidative α-tosyloxylation of alcohols were compared with those of [hydroxy(tosyloxy)iodo]benzene.
