During a Friedel-Crafts acylation, why is it necessary to use more than one full stoichiometric equi — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

Unlike alkylation where the catalyst is regenerated, the ketone product of acylation acts as a Lewis base and forms a highly stable complex with AlCl3, removing it from the catalytic cycle. Aqueous workup is required to release the product.
