Abstract : Claisen-Schmidt condensation defined when benzaldehyde derivatives condensed with alkyl/aryl ketone in basic medium to afford ?, ?-unsaturated ketone. It follows cross aldol condensation type mechanism where intermediate is aldol which dehydrate in presence of acid/alkali to afford final unsaturated ketone which is known as “chalcone”. Generally, polar solvents favour the reaction kinetics to afford product in excellent yield.
