Condensation reaction
A condensation reaction is a class of organic addition reaction that typically proceeds in a step-wise fashion to produce the addition product, usually in equilibrium, and a water molecule (hence named condensation).[1] The reaction may otherwise involve the functional groups of the molecule, and formation of a small molecule such as ammonia, ethanol, or acetic acid instead of water.[2] It is a versatile class of reactions that can occur in acidic or basic conditions or in the presence of a catalyst. This class of reactions is a vital part of life as it is essential to the formation of peptide bonds between amino acids and the biosynthesis of fatty acids.[3]
Many variations of condensation reactions exist, common examples include the aldol condensation, Claisen condensation, Knoevenagel condensation, and the Dieckman condensation (intramolecular Claisen condensation).[4]
