The Friedel-Crafts reaction is a typical electrophilic substitution reaction in the aromatic nucleus; the role of the catalyst amounts to the generation of an attacking particle—an alkyl or acyl cation. Examples are given below of the interaction of benzene with the ethyl chloride and the acid ...

Friedel-Crafts Acylation 1,162 An illustration describing both the Friedel-Crafts reactions undergone bybenzeneis provided below. It can be noted that both these reactions involve the replacement of a hydrogen atom (initially attached to the aromatic ring) with an electrophile. Aluminium trichloride ...

In Friedel-Crafts acylation, the acyl group [-C(O)R] forms an acylium ion in the presence of AlCl3. The acylium ion attacks the benzene ring, forming a complexed intermediate in which the ring loses its aromaticity. Next, the AlCL4ion removes a proton from the ring restoring the ring...
