| Abstract: | An operationally simple, mild and single-step method for the direct and metal-free synthesis of aryl carboxylate esters is described under a solvent free condition. The reaction of phenols including 2-naphthol (or 1-naphthol) with a variety of carboxylic acids in the presence of TFAA and 85% H3PO4 provided a range of aryl carboxylate esters in good yields within few minutes. |
| Keywords: | Trifluoroacetic anhydride Phosphoric acid O-acylation Phenol Naphthol Carboxylic acid |
