Dibenzalacetone is commonly synthesized through the aldol condensation of benzaldehyde with acetone. This reaction typically involves the following steps:
-
Deprotonation of Acetone: Under basic conditions (often using a strong base like sodium hydroxide or potassium hydroxide), the acetone is deprotonated to generate an enolate ion.
-
Nucleophilic Attack: The enolate ion then acts as a nucleophile and attacks the carbonyl carbon of a benzaldehyde molecule, forming a β-hydroxy ketone intermediate.
-
Condensation: The β-hydroxy ketone can lose a water molecule (dehydration), resulting in the formation of an α,β-unsaturated ketone, specifically dibenzalacetone.
The general reaction can be summarized as follows:
\[ 2 \text{C}_6\text{H}_5\text{CHO} + \text{C}3\text{H}6\text{O} \xrightarrow{\text{Base}} \text{C}{15}\text{H}{14}\text{O} + \text{H}_2\text{O} \]
