3) Historically, the benzylidene group (=CHPh) has been called the benzal group because it is easily added to a carbonyl compound by aldol condensation with benzaldehyde. ... Then stir the reaction for another 30 min. Cool the mixture using the ice-water bath. Collect the crystals by vacuum filtration. Wash the crystals...

Abstract: The purpose of this experiment was to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. This was done by mixing the two reactants with NaOH and ethanol, then allowing the reaction to sit for thirty minutes.

The purpose of this experiment is to synthesis dibenzalacetone (trans, trans-1,5-diphenyl-1,4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis begins by using strong base to generate the acetone The equilbrium position of this reaction strongly favors the starting acetone,

It is also possible to utilize two different aldehydes or ketones in an aldol-type condensation reaction. ... This molecule can also be prepared by the condensation of ethyl acetoacetate with benzaldehyde, followed by dehydration and decarboxylation, as shown below.

As we can see in our experiment we have acetone and benzaldehyde: ( ); ... Notice also the C-C double bond is conjugated with the carbonyl group, if you face this type of reaction ( aldol condensation ) you should know the position of the double bond takes place in the most stable state, in other words, in the conjugated...

Like the Grignard reaction, the Aldol Condensation is an extremely useful carbon-carbon bond-forming reaction in organic chemistry. Aldol reactions are a little easier to perform because you do not have to worry about keeping things dry. ... benzaldehyde 113 189 118 99...

Lastly, how can I modify the aldol condensation from dibenzalacetone to get firstly, ... The side products expected in this reaction are benzaldehyde and benzalacetone. The side products are removed by sufficient amount of ethanol. To synthesize benzalacetone I would take one equivalent of benzaldehyde and mix it or react...
