WebApr 6, 2024 · Generally speaking, an aldol condensation is a nucleophile attack on a carbonyl to make a ketone or aldehyde of β-hydroxy. The nucleophile is generally an enolate of an aldehyde or ketone attacking another aldehyde or ketone molecule. An acidic or basic solution can catalyze the condensation of aldol. By bases such as hydroxide ions and ... Webthis process is known as the Aldol condensation. In a self-Aldol condensation, the same carbonyl compound condenses with itself, whereas in a mixed-Aldol condensation, the two carbonyl compounds are different. In the second case, careful choice of both components is required so that only a single product is formed. Usually one component is
