WebIf we look at the mechanism of reaction between an aldehyde and an amine, we see how these factors balance. Here's the mechanism: It is an experimental fact that this reaction -- imine formation -- is acid catalyzed. WebThe reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation.
