Modified polyacrylamide supported chlorochromate was synthesized and used as a versatile and efficient oxidizing agent for the oxidation of various organic compounds such as hydroxyl compounds, silylethers, oximes, thiols, and other compounds. Over oxidation of the products (aldehydes to carboxylic acids) was not observed with this oxidizing agent. The oxidant was insoluble in oxidation media and chromium (VI) ions remained firmly bound to the insoluble polymeric support after the oxidation reaction. The mild reaction condition, easy work-up, short reaction times, regenerability of the reagent and its easy preparation and handling are among the advantages of this new polymeric chlorochromate reagent
