The oxidation of alcohols using polystyrene‐based benzyltriethylammonium dichloroiodate, tetrachloroiodate and dichlorobromate reagents is described. On reaction with different alcohols, the polymeric polyhalide reagents afforded the respective carbonyl compounds in high yields. The insoluble spent reagents could be regenerated and reused without significant loss in reactivity. The reactivities of the polymeric polyhalides were investigated as a function of the nature of solvents, effective molar concentration of the reagent, temperature and by varying the polarity of the macromolecular support, and the results are discussed. © of SCI.
