What is the mechanism of Friedel-Crafts acylation?
The Friedel-Crafts acylation reaction involves the electrophilic substitution of an acyl group onto an aromatic ring. The mechanism begins with the formation of an acylium ion from the acyl chloride in the presence of a Lewis acid catalyst, such as aluminum chloride. The acylium ion then reacts with the aromatic ring to form a resonance-stabilized carbocation intermediate. Finally, a proton is abstracted from the carbocation intermediate by the Lewis acid catalyst to regenerate the aromatic ring and complete the acylation reaction. **

The Friedel-Crafts acylation is a reaction in which an acyl group is introduced onto an aromatic ring. The mechanism involves the formation of an acylium ion intermediate from the reaction between an acyl chloride and a Lewis acid catalyst, typically aluminum chloride. This acylium ion then reacts with the aromatic ring to form a new carbon-carbon bond, resulting in the acylated product. The Lewis acid catalyst helps in the formation of the electrophilic acylium ion and also facilitates the regeneration of the catalyst at the end of the reaction. **
