Abstract

Chalcones were prepared by condensation (Claisen Schmidt) reaction of Acetophenone, o-Hydroxyacetophenone
with Benzaldehyde, employing conventional and microwave assisted-solvent free method.
This reaction was carried out with use of fresh anhydrous Na2CO3 as catalyst by avoiding hazardous
bases like NaOH and KOH for the condensation process which is ecofriendly and covers Green chemistry
aspects. Their biological Activities were also evaluated.
