Question:

What is the name of the product formed by a double aldol condensation between {eq}4-{/eq}methoxybenzaldehyde and cyclohexanone?

Aldol Condensation Reaction:

In aldol condensation, first the formation of enolate ion occurs by the abstraction of alpha hydrogen from aldehyde or ketone. The enolate ion then on reaction with carbonyl compound followed by dehydration yields beta-hydroxyl aldehydes or ketones as the final product.

Answer and Explanation: 1


The double aldol condensation that occurs between 2 molecules of 4-methoxybenzaldehyde and 1 molecule of cyclohexanone results in the formation of (2E,6E)-2,6-bis(4-methoxybenzylidene)cyclohexanone as the final product by the removal of two water molecules.


The double aldol condensation reaction is shown below.
