Question:

Although acid is not needed to dehydrate the aldol products, it will enhance the reaction of the aldol product. Write a mechanism for this acid-catalyzed dehydration reaction.

Aldol Reaction:

The aldol reaction is a reaction between two carbonyl compounds. Aldol reactions often proceed through as aldol condensation if the participating enolates are formed only in equilibrium.

Answer and Explanation:

Under the reaction condition an aldol reaction occur first and it leads to formation of the beta-hydroxy carbonyl compound. Then E1 elimination takes place (dehydration).

The mechanism for the acid-catalyzed dehydration reaction is shown below.
