The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β- diketone. The reaction between an aldehyde or ketone having an α-hydrogen with an aromatic carbonyl compound lacking an α-hydrogen is called the Claisen–Schmidt condensation.

It is named after Rainer Ludwig Claisen, … The condensation of an aromatic aldehyde with an aliphatic aldehyde or ketone in the presence of a base or an acid to form an α,β‐unsaturated aldehyde or ketone with high chemoselectivity is generally known as Claisen–Schmidt condensation. The Claisen-Schmidt Reaction The Claisen-Schmidt condensation between acetophenone and benzaldehyde derivatives is an important C-C bond forming reaction which allows unsaturated ketone such as chalcones tobe obtained (23). 1.
