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. 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.
WebThe aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872. 1 In an aldol condensation, an enolate ion reacts with a carbonyl compound in the presence of acid/base catalyst to form a β-hydroxy aldehyde or β-hydroxy ketone, followed by dehydration to ...

Role of sodium hydroxide.
WebClaisen condensation. The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β- diketone. [1] It is named after Rainer Ludwig Claisen, who first published his work on the reaction in 1887.
WebThe aldol condensation is a reaction that is named based on the type of product formed when two aldehydes (or ketones), in the presence of dilute base, yields a molecule having both alcohol and aldehyde functional groups. ...
