of the 7-bonds of benzene to
ring and regenerate the catalyst (step 3). When the acyl group is acetyl (CH3
as the acylating agent rather than acetyl chloride. The anhydride is safer to work with and it usually prov
better yields and a simpler work-up. More catalyst is needed with acetic anhydride however, because som
the aluminum chloride complexes with the acetic acid produced during the reaction, making it ineffective
catalyst. As a rule, 2-3 moles of AlCl3 are used per mole of acetic anhydride.
