Definition of Friedel Crafts Acylation



Reactions are organic coupling reactions that have electrophilic aromatic substitutions involved in them. The aromatic substitutions are used to attach the substituents to the aromatic rings. There are two types of Friedel Crafts reactions namely Friedel Crafts Alkylation and Friedel Crafts Acylation. Friedel Crafts Acylation is such a type of reaction in which an acyl group is added into the aromatic ring.

 


A catalyst such as AlCl3 along with an acid anhydride is usually employed. In this reaction, a ketone is formed as a result of the transformation of the aromatic ring. In the case of amines and alcohols, the acylation takes place on the atoms of nitrogen and alcohol respectively.
