Synthesis of Aromatic Ketones Friedel-Crafts Acylation

Synthesis of Aromatic Ketones (Friedel-Crafts Acylation) 

The Friedel-Crafts acylation, the reaction of an aromatic compound with an acid chloride and a Lewis acid (such as AICI3), adds an acyl group to the aromatic ring to give an aromatic ketone product. like the previously discussed alkylation reaction, it involves a strongly electrophilic carbocation (called an acylium ion), but this carbocation is not subject to rearrangement since it is stabilized by resonance.
