Studies on N-acetylation of anilines with acetyl chloride using phase
N-acetylation of anilines with acetyl chloride leads to the production of one equivalent acid which will form salt with unreacted aniline The addition of an |
Acetanilide is prepared from aniline when it reacts with acetic anhydride/glacial acetic acid in the presence of zinc dust.
What is the acetylation of aniline?
Aniline refers to the formation of Acetanilide by nucleophilic replacement reaction with acetic anhydride and the reaction is called acetylation.
Aniline serves as the nucleophile in this reaction and acetic anhydride group acyl (CH3CO-) acts as the electrophile.
What is the reaction of aniline?
Anilines – Reactions
Basicity- As it is known that anilines are weak bases.
On reaction with strong acids, the compounds form ions of anilinium.
Acylation- In acylation reaction, anilines reacts readily with carboxylic acids forming amides.
