PDF	Efficient acetylation of primary amines The present methodology illustrates the efficient acetylation of primary amines and amino acids in brine solution by means of acetyl chloride under weakly basic

What is the acylation of primary 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.
The reactions are carried out in the presence of a stronger base as compared to amines.
What is the acetylation 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.

Acylation of primary amines occurs selectively in the presence of tertiary (3i) and unprotected secondary amine groups (3j). Substrates having double bonds, which may be sensitive to chlorinating agents, were also good substrates (3k), although small amounts of halogenated byproducts were observed.
