POLY(N-BROMOACRYLAMIDE) - A NEW POLYMERIC RECYCLABLE OXIDIZING AND BROMINATING REAGENT

Poly(N-bromoacrylamide) was conveniently prepared from commercially available polyacrylamide and was developed as a new insoluble polymeric oxidizing and brominating reagent for organic substrates. The polymer was characterized by elemental analysis and IR spectra. The reagent, which was prepared by the reaction of potassium hypobromite with polyacrylamide, has a capacity of 5. 2-5. 7 mmol of bromine per gram. Alcohols were oxidized to the corresponding carbonyl compounds in near quantitative yields at room temperature with this reagent. The reagent was also used to brominate unsaturated and aromatic substrates in high yields.
