This reaction takes place between two molecules of esters (same or different). One ester should have atleast one alpha-hydrogen atom which behaves as a reagent. The reaction is catalyzed by strong bas elike C_(2)H_(5)barONa^(+) in presence of C_(2)H_(5)OH. The product of this reaction is beta-ketoster: Which among the following is the most reactive towards Claisen condensation ?
