When the Carboxyl group reacts with the molecule of the Amine group which upon heating form an Amide group.
They are represented by the general formula .
Example of an amide:
Aliphatic and aromatic primary and secondary amines undergo into acylation reaction when treated with acid chlorides, anhydrides, or esters to form a nucleophilic substituted amide.
This reaction consists of the replacement of the hydrogen atom of group.
To shift the equilibrium to the right-hand side, the formed during the reaction is removed as soon as it is formed.
This reaction is carried out in the presence of a base (such as pyridine) which is stronger than the amine.
