Abstract

Abstract: A simple and efficient method has been developed for the oxybromination of six kinds of polycyclic aromatic hydrocarbons with the use of aqueous hydrobromic acid and hydrogen peroxide. The method requires no catalysts, and achieves bromination via the in situ generated active bromine. By controling the reaction temperature and the amount of bromination agent, the reaction can obtain the monobromination or dibromination of polycyclic aromatic hydrocarbons with a yield of 51.1%~94.2%. The oxybromination method is simple, safe, environmental friendly, and suitable for industrial production. The obtained products have been characterized by melting point measurement and 1H NMR.

Key words: polycyclic aromatic hydrocarbons, oxybromination, selectivity, environment friendly
