acetylation of amine mechanism
Mechanism of Acetylation of Salicylic Acid
This acetate ion goes on to associate with the proton liberated by the phenolic OH group (hydroxy group) of the salicylic acid molecule, resulting in the formation of acetic acid (CH3COOH).
What is the mechanism of amine acylation?
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 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.
