POLY(METHYL METHACRYLATE) SUPPORTED ISOXAZOLINIUM CR(VI) SPECIES AS OXIDIZING REAGENTS

Poly(methyl methacrylate) supported isoxazolinium chromate and chloroc hromate have been developed as a new class of regenerable solid phase reagents for oxidation of alcohols. The reagents are prepared by a ser ies of polymer analogous reactions starting from 2% divinylbenzene (DV B), ethyleneglycol dimethacrylate (EGDMA) and NN'-methylene-bis-acryla mide (NN'MBA) crosslinked poly(methyl methacrylate) resins. NN'MBA cro sslinked resin is found to possess higher functional group capacity, a nd reactivity in terms of reaction period and product yield. These rea gents are found to oxidise primary and secondary alcohols to the corre sponding carbonyl compounds in high yields.
