  • Patent number: 6956142
    Abstract: A new eco-friendly process is described in the present invention for the preparation of bromobenzene through substitution of one of the C—H proton of benzene ring with a highly reactive hypobromous acid generated in situ, said process comprises the steps of activating a water soluble, easy to handle, brominating reagent with a mineral acid at elevated temperature and atmospheric pressure to generate active bromine species which in turn reacts with benzene.

  • Patent number: 6838582
    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.
