POLYHALIDE DERIVATIVES OF POLYSTYRENE-BASED BENZYLTRIETHYLAMMONIUM RESINS AS OXIDIZING REAGENTS - SYNTHETIC AND REACTIVITY CORRELATIONS

The oxidation of alcohols using polystyrene-based benzyltriethylammoni um dichloroiodate, tetrachloroiodate and dichlorobromate reagents is d escribed. On reaction with different alcohols, the polymeric polyhalid e reagents afforded the respective carbonyl compounds in high yields. The insoluble spent reagents could be regenerated and reused without s ignificant loss in reactivity. The reactivities of the polymeric polyh alides were investigated as a function of the nature of solvents, effe ctive molar concentration of the reagent, temperature and by varying t he polarity of the macromolecular support, and the results are discuss ed.
