Concept introduction:
When aldehydes or ketones react with a secondary amine, formation of enamine takes place. The nitrogen analog of an enol is known as enamine. The nucleophilic addition reaction of the secondary amine to the carbonyl carbon atom results in the formation of hemiaminal intermediate which further on dehydration forms the enamine product.
