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 … WebSynthesis of Dibenzalacetone. Aldol condensation is an important route of organic synthesis because it provides an efficient way to form carbon-carbon bond. In this …

WebThe preparation of dibenzalacetone (1,5-diphenyl-1,4-pentadien-3-one) is an example of an aldol condensation in which the ketone, acetone, possesses two sets, albeit equivalent, of alpha-hydrogens. The original product, benzalacetone, contains a set of alpha-hydrogens which can be used to effect another nucleophilic substitution onto a second ...
