| Abstract: | A new and efficient synthesis of 3-bromoflavone using 1,3-dibromo-5,5-dimethyl-imida- zolidine-2,4-dione as brominating agent under microwave irradiation was reported. The effects of molar ra- tio of reactants, reaction temperature and reaction time on the yields of product were investigated. Compared to the traditional heating method, microwave assisted synthesis shortened the reaction time from several hours to 15 min and gave better yields of products. |
