This electrophilic aromatic substitution allows the synthesis of acylated and alkylated products from the reaction between arenes and acyl chlorides/anhydrides or alkyl chlorides [2008OL(10)2645]. Normally, a stoichiometric amount of the aluminium-based LA catalyst is required in acylation because both the substrate and the product form complexes. Triethylammonium acetate is a volatile buffering agent, which, when diluted in water, maintains pH at about 7. That's the general form of any acylation: organic substrate + acylating agent = acylated organic substrate.
