    Aldol Condensation. In some cases, the adducts obtained from the Aldol Addition can easily be converted (in situ) to α,β-unsaturated carbonyl compounds, either thermally or under acidic or basic catalysis. The formation of the conjugated system is the driving force for this spontaneous dehydration. Under a variety of protocols, the condensation product can be obtained directly without ...

    Both the aldol reaction and condensation are reversible. In aldol reactions between two molecules of the same aldehyde are generally quite successful, since the equilibrium lies far to the right, and the yields are very high. E.g. The formation of aldol (β-hydroxy butyraldehyde) from two molecules of acetaldehyde and subsequent dehydration to crotonaldehyde occurs readily in presence of a ...

    Condensations are called reactions in which a larger molecule is formed from smaller components, eliminating a very small by-product such as water. The following examples are therefore properly referred to as condensations of aldols. In the presence of acid and base catalysts, the dehydration step of an aldol condensation is also reversible ...

    Therefore, the aldol reaction is extensively used to lengthen the molecule. The final aldol product is called β- Hydroxy carbonyl compound. If the aldol product is not isolated and placed in a base for a long time, it loses water and forms double bond through condensation, which is the reason why aldol reaction is called aldol condensation.
