Aldol Condensation Mechanism & Alpha Hydrogen Reactions
Mechanism of Aldol Condensation in Ketonic Compounds. The reactivity of ketones towards aldol condensation is less in comparison to aldehydes. However, a small quantity of aldol product formation is possible with the use of acid catalysts in the reaction. The aldol compound formed will soon dehydrate to form a resonance stabilized compound.
