[PDF] acetylation of aniline reaction mechanism

Aniline reacts with acetic anhydride to form Acetanilide by nucleophilic substitution reaction and the reaction is called acetylation. In this reaction, aniline acts as the nuclepohile and acyl (CH

  • What is the acetylation reaction of aniline?

    - The acetic anhydride reacts with aniline, the reaction is known as ethanoylation or acetylation reaction, which produces a product which is named as acetanilide and acetic acid is another product.

  • 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 mechanism of aniline to acetanilide?

    The reaction between aniline and acetic anhydride is characterized by a nucleophilic acyl substitution. The mechanism involves the nucleophilic attack on the carbonyl carbon of acetic anhydride by the nitrogen on aniline. The tetrahedral intermediate that forms then collapses to form acetanilide and acetic acid (2).
  • Reason: Acetylation of aniline results in decrease of electron density on nitrogen. Acetanilide is less basic than aniline.
