POLYMERIC ANALOG OF ISOXAZOLINIUM PERMANGANATE - PREPARATION AND USE AS SYNTHETIC REAGENT

A crosslinked polystyrene-supported solid phase analog of isoxazoliniu m permanganate was prepared and used as a recyclable oxidizing reagent . The reagent was prepared by a series of polymer-analogous reactions starting from styrene-divinyl benzene(DVB) and styrene-ethyleneglycol dimethacrylate(EGDMA)(2%) crosslinked polymer. The reagent was found t o oxidize alcohols to carbonyl compounds in near-quantitative yield. T he EGDMA crosslinked polystyrene-supported isoxazolinium permanganate was found to be more efficient in terms of capacity, reaction time, an d product yield. The spent polymeric reagent after the oxidation step can be easily removed by filtration and can be regenerated and reused several times. (C) 1997 John Wiley & Sons, Inc.
