Abstract
Polystyrene-supported isoxazolinium chromate and chlorochromate resins were prepared and developed as recyclable reagents for oxidation of a lcohols to carbonyl compounds. Divinylbenzene (DVB) and ethylene glyco ldimethacrylate (EGDMA) crosslinked polystyrene resins (2%) were used as the macromolecular supports. These insoluble Cr(VI) reagents were f ound to be selective in carrying out oxidation reactions. EGDMA-crossl inked polystyrene-supported reagents showed higher reactivity in terms of functional group capacity, reaction time and product yield. The sp ent reagent can be recycled and reused without appreciable loss of rea ctivity.
