WebIn aldol condensation, an enolate ion reacts with another carbonyl compound to form a conjugated enone. 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. Created by Jay. WebThe basic mechanism for the two types of reactions is the same. This beta-hydroxy carbonyl compound formed from the aldol condensation can be dehydrated in the presence of an acid or a base to produce an unsaturation at the alpha-beta position. Dehydration of aldol products can lead to the formation of enones.
