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).
