Condensación de Claisen (acetato de etilo)

2CH3COOC2H5 → CH3COCH2COOC2H5 + C2H5OH

Descripción general

Two molecules of ethyl acetate undergo base-catalyzed condensation to form ethyl acetoacetate (a beta-keto ester) and ethanol. The enolate of one ester molecule attacks the carbonyl of another, displacing ethoxide. This is the ester analogue of the aldol reaction.
