Mixed Aldol Condensation.
Aldol Condensation of RCHO. 20.5 The Aldol Condensation You may have noticed that aldehydes were conspicuously absent from the examples of alkylation reactions presented in Sections 20.3 and 20.4. There are no recommended articles. The process occurs in two parts: an aldol reaction, which forms an aldol product, and a dehydration reaction, which removes water to form the final product. Mechanism; Condensation Types; An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone, followed by dehydration to give a conjugated enone.. Aldol condensations are important in organic synthesis, because they provide a good way to form carbon–carbon bonds.

Aldol condensations between different carbonyl reactants are called crossed or mixed reactions, and under certain conditions such crossed aldol condensations can be effective.
Example 23.5.1: Mixed Aldol Reaction (One Product) The success of these mixed aldol reactions is due to two factors.
