Abstract
Divinylbenzene (DVB), ethylene glycol dimethacrylate (EGDMA) and N,Nβ²βmethylenebis(acrylamide) (N,Nβ²MBA) crosslinked poly(methyl methacrylate) (PMMA) was functionalised to generate isoxazolinium permanganate resins. These resins were found to selectively oxidise alcohols to the corresponding carbonyl compounds in appreciable yields. These reagents were found to possess the characteristics of polymeric reagents including operational simplicity.

Insoluble polymeric dichromate and chlorochromate reagents were prepared by modification of poly(methyl methacrylate-co-divinylbenzene) beads with ethylene diamine followed by treatment of the resulting resin with excess methyl iodide and subsequent reaction with aqueous chromium trioxide or chromiu
