Ecofriendly bromination of chalcones and synthesis of flavones using grinding technique

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.

Bromhydrination of Chalkones in Dimethyl Sulphoxide

A novel method developed for the preparation of α-bromo-β-hydroxychalkones (IIIa-d) involves bromhydrination of the corresponding chalkones (Ia-d) with bromine water in dimethyl sulphoxide at room temperature.
