Is self condensation of Cinnamaldehyde a possibility?
No aldol condensation is not possible here, as you would have to extricate an alpha hydrogen(alpha to the carbonyl group), but if you do extricate a hydrogen atom from the alpha position it would result in the formation of Vinylic Carbanion which is very very unstable.
How Cinnamaldehyde is formed?
HOW IT IS MADE. Cinnamaldehyde is prepared commercially by treating the bark of the Cinnamomum zeylanicum tree with steam. The aldehyde dissolves in the steam and can then be extracted as the steam cools and condenses to form cold water, in which the compound is much less soluble.
How do you prevent self condensation of aldehydes?
Preventing self-condensation
- The use of a more reactive electrophile, and a non-enolizable partner.
- Making enolate ion quantitatively.
- Silyl enol ether formation.
What is Phenylacetaldehyde used for?
Phenylacetaldehyde is used in the synthesis of polyesters where it serves as a rate-controlling additive during polymerization.
What gives cinnamon its Flavour?
Cinnamaldehyde is an organic compound with the formula C6H5CH=CHCHO. Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor.
Can cinnamaldehyde be synthesized artificially?
Several synthetic methods have been reported for the generation of cinnamaldehydes, including oxidative enamine catalysis [35,36], the use of a palladium-catalyzed Heck-Saegusa reaction [37], and Dess-Martin oxidation of alcohols [38].
What is the constitutional formula for cinnamaldehyde?
C6H5CH=CHCHO
Cinnamaldehyde is an organic compound with the formula C6H5CH=CHCHO. Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor.
Which aldehyde can undergo self-condensation?
Hint:Aldehydes having α -hydrogen undergo self-condensation on warming with dilute or mild base to give β -hydroxy aldehydes, called aldols (aldehyde + alcohol). This reaction is known as aldol condensation.
What is self-condensation in organic chemistry?
Illustrated Glossary of Organic Chemistry – Self condensation. Self condensation: A condensation reaction in which two of the same molecule are condensed. This aldol condensation is a self condensation reaction because two molecules of acetone combine to form the product.

What are the steps involved in the condensation reaction of cinnamaldehyde?
The first three involve the formation of an aldol (from aldehyde alcohol). The final two steps involve dehydration of the aldol to produce the final products, an unsaturated ketone, and water: The reaction of cinnamaldehyde with acetone is essentially a “double” aldol condensation, catalyzed by hydroxide ions.
What is the product of aldol condensation reaction with cinnamaldehyde?
The product of the first step, a ketone, can itself react like acetone with cinnamaldehyde in a second aldol condensation reaction to form the final product: Hope you would have staisfied.
Is it possible that the synthesized product is cinnamaldehyde?
Based on the results, it can be concluded that that synthesized product was different from the starting materials and that it was possible that the product was cinnamaldehyde due to the highly colored hydrazone formed.
What is the reaction between cinnamaldehyde and acetone?
