Claisen condensation involves :

Assertion: Esters which contain alpha- hydrogens undergo Claisen condensation. Reason : LiAIH_(4) reduction of esters gives acids

Assertion: Esters which contain alpha- hydrogens undergo Claisen condensation. Reason : LiAIH_(4) reduction of esters gives acids

The compound formed by Claisen condensation of

Explain : Ethyl isobutyrate does not undergo Claisen condensation in the presence of NaOEt .

Ester gives nucleophilic addition reaction followed by elimination reaction with carbon nucleopile. When carbon nucleophile is of an ester then the reaction is known as Claisen condensation reaction. This reaction is also carried out between ester and a ketone. A suC Cessful Claisen condensation requires an ester with two alpha- hydrogens and an equivalent amount of base rather than a catalytic amount of base. Intramolecular Claisen condensation given diester is known as :
