acylation reaction of amines

What is the acylation of amides?
Acylation is one type of basic organic transformation to form amides or esters, which can be accelerated using a nucleophilic catalyst.
Pyridine can act as a nucleophile for activated carboxylic acids and is often used as a catalyst in acylation reactions.
What is the alkylation reaction of amines?
Amine alkylation (amino-dehalogenation) is a type of organic reaction between an alkyl halide and ammonia or an amine.
The reaction is called nucleophilic aliphatic substitution (of the halide), and the reaction product is a higher substituted amine.
Acylation of amines and alcohols generally proceeds via free radical mechanism which involves the formation of acyl carbonium ion (2) and the efficiency of the generation of this ion is very important.
The plausible mechanism is described schematically in Scheme 1.

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.
