Synthesis of salicylates from anionically activated aromatic trifluoromethyl group

An efficient approach to salicylates via a novel transformation of anionically activated aromatic trifluoromethyl group is described. Anionically activated trifluoromethyl group can react with phenols/alcohols under alkaline conditions to afford aryl/alkyl salicylates in high yields. Mechanism studies indicate that the carbonyl oxygen atom of ester is from the H2O in the solvent.

A photoredox-neutral Smiles rearrangement of 2-aryloxybenzoic acids

We report on the use of visible light photoredox catalysis for the radical Smiles rearrangement of 2-aryloxybenzoic acids to obtain aryl salicylates. The method is free of noble metals and operationally simple and the reaction can be run under mild batch or flow conditions. Being a redox neutral process, no stoichiometric oxidants or reductants are needed.

Acylation of Phenols with Salicylic Acid Using Polyphosphoric Acid

Acylation of 2-naphthol (2), 1-naphthol (6) and resorcinol (11) with salicylic acid (1) in the presence of PPA affords salicylate esters (4, 7, 13 and 14), 1,2-benzoxanthone (5), 3,4-benzoxanthone (8), 3-hydroxyxanthone (12), 2-salicoyl-1-naphthol (9) and 11-hydroxy-12H-benzoxanthen-12-one (10).Compounds (4, 5, 7, 8, 12, 13 and 14) are identical with those obtained by heating a mixture of phenyl salicylate (3) and phenols (2, 6 and 11).
