ResumoInsoluble polymer-bound triphenylphosphonium perbromide was prepared by chemical modification of poly(methyl methacrylate) resin. The polymeric reagent was used for the bromination of alkenes, carbonyl compounds and arenes under mild conditions. In addition to the excellent yields of the brominated products and the ease and simplicity of the method, the resulting polymeric by-product could be simply regenerated and re-used.
