Polymer-supported oxidation of alcohols was conducted very efficiently by employing oxoammonium salts, the reactive intermediates in TEMPO oxidations (TEMPO=2,2,6,6-tetramethylpiperidinoxyl). These highly reactive salts (see scheme; X=Br, Cl) could be prepared and isolated on the polymeric support, and were used for the conversion of single compounds as well as of complex mixtures of alcohols.
