[PDF] acylation reaction of amines

Aliphatic and aromatic, primary and secondary amines react with acid chlorides, anhydrides and esters by the process of nucleophilic substitution reaction. This is known as acylation. Amides are the end products of acylation.

  • What 3 types of reactions will amines undergo?

    Acetylation is often used to place an acetyl protecting group on primary or secondary amines to reduce their reactivity toward oxidizing agents or electrophiles. Acetamides are usually crystalline solids which can be a help in purification by recrystallization.

  • What is the purpose of acetylation of amines?

    In case of tertiary amines, there is no replaceable H atom and therefore, these do not react with acetyl chloride or acetic anhydride and hence do not undergo acylation.

  • Why amines do not undergo acylation?

    A typical example is the reaction of benzene sulfonyl chloride with aniline. The Hinsberg test, which can distinguish primary, secondary, and tertiary amines, is based upon sulfonamide formation. In the Hinsberg test, an amine is reacted with benzene sulfonyl chloride.
