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. Experiment 19 — Aldol Condensation _____ Pre-lab preparation. An aldol reaction between two different carbonyl compounds is called a crossed aldol or mixed aldol reaction. In aldol condensation, ?-hydroxy ketone is formed which on dehydration give unsaturated ketone. ... Will cinnamaldehyde undergo self-aldol condensation? Vidallon, Mark Louis P. Date Performed: February 20, 2012 CHEM44.1 2L Date Submitted: March 12, 2012 MIXED-ALDOL CONDENSATION Synthesis of Cinnamaldehyde I. The aldol condensation between benzaldehyde and acetaldehyde followed by dehydration to obtain cinnamaldehyde is shown below. Aldol condensation occurs in aldehydes having α-hydrogen with a dilute base to give β-hydroxy aldehydes called aldols. This reaction is most commonly known as aldol condensation. Questions tagged [aldol-reaction] Ask Question This tag should be applied to questions about mechanisms, selectivity, or other aspects of aldol reactions. aldol condensation writer: emily norwood reviewer: miklynn gebhart editor: erin bishop introduction: russian chemist alexander borodin discovered the aldol My book says it won't, but since it has an α-hydrogen, I'm confused. 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. the reaction at the top of the next page, but with a 1:1 ratio of ketone and aldehyde). (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. Remember
