Dibenzalacetone by the aldol condensation
WebDrucillah Nalukwago Introduction This is a mixed condensation reaction (Claisen condensation). Dibenzalacetone is prepared by using 2 moles of benzaldehyde and acetone. The aldehyde carbonyl is more reactive than that of acetone therefore it reacts rapidly with the anion of the ketone forming a beta-hydroxy ketone, which can easily … Webtheoretical yield and percent yield help for Aldol condensation. here's the reaction we did in lab. it's.
