Aldol - Wikipedia, the free encyclopedia
An aldol or aldol adduct is a beta-hydroxy ketone or aldehyde, and is the product of aldol addition (as opposed to aldol condensation, which produces an α,β-unsaturated carbonyl moiety). Typically...

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.

In the presence of acid or base catalysts the aldol reaction is reversible, and the beta-hydroxy carbonyl products may revert to the initial aldehyde or ketone reactants. In the absence of such catalysts these aldol products are perfectly stable and isolable compounds.
