Selective bromination of chalcones and 2'-hydroxychalcones has been carried out with ammonium bromide and ammonium persulphate using grinding technique at RT under aqueous moist condition to give α,β-dibromochalcones and α,β-dibromo-2'- hydroxychalcones respectively. α,β- Dibromo-2'-hydroxychalcones have been cyclodehydrobrominated with barium hydroxide moist and ethanol at RT to give flavones using grinding technique.

The reaction of 2'-OR-4-R1 chalcone with N-bromosuccinimide is reported.It was found that the structure of the product depends on the nature of the substituents R and R1.The prepared α-bromo-β-methoxydihydrochalcones were converted to the corresponding aurones.
