The aldol condensation between benzaldehyde and acetaldehyde followed by dehydration to obtain cinnamaldehyde is shown below. the reaction at the top of the next page, but with a 1:1 ratio of ketone and aldehyde). My book says it won't, but since it has an α-hydrogen, I'm confused. An aldol reaction between two different carbonyl compounds is called a crossed aldol or mixed aldol reaction. 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. Remember

(1) Write the mechanism of the base-catalyzed aldol condensation of acetone and a generalized aromatic aldehyde, Ar–CH=O to give the α,β-unsaturated product (i.e. Aldol condensation occurs in aldehydes having α-hydrogen with a dilute base to give β-hydroxy aldehydes called aldols. ... Will cinnamaldehyde undergo self-aldol condensation?

This reaction is most commonly known as aldol condensation. Experiment 19 — Aldol Condensation _____ Pre-lab preparation. Questions tagged [aldol-reaction] Ask Question This tag should be applied to questions about mechanisms, selectivity, or other aspects of aldol reactions. In aldol condensation, ?-hydroxy ketone is formed which on dehydration give unsaturated ketone. Cinnamaldehyde derivatives were synthesized in good to excellent yields in one step by a mild and selective, base-free palladium(II)-catalyzed oxidative Heck reaction starting from acrolein and various arylboronic acids.
