Reagents for aldol condensation
Web2. Claisen Condensation. The aldol reaction, is a remarkable and useful reaction of aldehydes and ketones in which the carbonyl group serves both as an electrophilic reactant and the source of a nucleophilic enol species. Esters undergo a similar transformation called the Claisen Condensation. Four examples of this base-induced reaction, which ... WebThe reason for this formation is because the Aldol product is not usually isolated seen. The formation of an α, β unsaturated ketone is done through an elimination reaction (1). As seen in figure 4, a good elimination solvent is used to take the hydrogen (2). In this experiment, the specific aldol condensation done is mixed.

WebWhat makes this reaction a crossed aldol condensation, and why is it easier to achieve a good yield of a single product using these specific reagents (aromatic aldehyde and symmetrical ketone) than many other aldol condensation reactions? Show transcribed image text. Expert Answer. WebAnswer. a) Aldol condensation: This occurs when two molecules of aldehydes or ketones with ɑ–hydrogen atoms are treated with dil. NaOH condenses to form β-hydroxy aldehydes or β–hydroxy ketones. b) Cross Aldol Condensation: Cross aldol condensation occurs when aldol condensation occurs between two different aldehydes or ketones.

Heating with base can result in loss of water to give a new C-C pi bond, giving a product we refer to as the Aldol Condensation product. Similar reactions can proceed with the enolates of other species.
