[PDF] acetylation of amine mechanism

  • What is the acetylation reaction of amines?

    The acetylation / acylation of amines takes place when the acetyl group substitutes the active hydrogen atom(s) attached to the nitrogen atom of the amine. This can take place by the attack of acetyl chloride on ammines. This is an excellent example of nucleophilic acyl substitution.
  • What is the mechanism of the acetylation reaction?

    Mechanism of Acetylation of Salicylic Acid
    Once the acetate ion establishes a stable bond with that of the nucleophilic oxygen atom (because of its free electrons) present in the salicylic acid, it undergoes dehydrogenation (the process of removal of a Hydrogen atom) in the process to yield acetic acid and aspirin.
  • What is the purpose of acetylation of amines?

    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.
  • Acetylation is a chemical reaction in which a hydrogen atom is substituted for an acetyl group (CH3C=O. group) in a compound. The products formed in acetylation reactions typically have an acetoxy functional group.
