| Abstract: | A highly pure 2,4,4,6-tetrabromo-2,5-cyclohexadienone has been prepared in a single pot, eco-friendly procedure in yields of 91-94% from phenol. In this method, a mixture of alkali/alkaline earth metal bromide and alkali/alkaline earth metal bromate was employed as brominating agent in place of corrosive liquid bromine. The reaction between phenol and the brominating reagent was initiated by the action of a mineral acid or moderately strong organic acid. The crude product was further characterized by standard analytical and spectroscopic methods. |
