A number of α,β-unsaturated carboxylic acids were reacted with electron rich arenes or heteroarene in the presence of trifluoroacetic anhydride (TFAA) and H3PO4 at room temperature to give a variety of chalcone derivatives in good to excellent yields. The methodology was used to prepare novel compounds of potential pharmacological significances.

Keywords: Chalcones, TFAA, α, β-unsaturated carboxylic acids, arenes
