Study Notes

Acylation Reactions Involving Amines

Aliphatic and aromatic primary and secondary amines react with acid chlorides, anhydrides, and esters to form amides.
In acylation reactions, a strong base (e.g., pyridine) is used to facilitate the reaction by removing the HCl formed during the reaction.
The products of acylation reactions involving amines are amides.
The reaction between amines and benzoyl chloride (C6H5COCl) is known as the Schotten-Baumann reaction.
At room temperature, amines react with carboxylic acids to form salts.

Description

Explore how aliphatic and aromatic primary and secondary amines react with acid chlorides, anhydrides, and esters through nucleophilic substitution to form amides in the acylation reaction. Understand the mechanism involving the replacement of hydrogen atoms by acyl groups. Learn about the role of pyridine as a base in shifting the equilibrium of the reaction.
