Purpose: Synthesize dibenzalacetone which is aldol compound by Claisen-Schmidt reaction to prove that reaction of an acetone with aldehyde, catalyzed by a strong base, yields an aldehyde + alcohol mixed compound known as (aldol).
WebMixed Aldol Condensation reaction. - a carbon-carbon bond forming reaction. - type of electrophilic substitution of the alpha-carbon in enols and/or enolates anions. - involves a dimerization of an aldehyde (or ketone) to a beta-hydroxy aldehyde (or ketone) by alpha C-H addition of one reactant molecule to the carbonyl group of a second. 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 …
