In this work, the reaction of derivatives of benzoic acid containing substituents in the aromatic ring (1a-o) with 2-chloro-4,6dimethoxy-1,3,5-triazine (4) in the presence of N-methylmorpholine (6) has been synthesized active triazine esters of carboxylic acids (3a-o). These compounds obtained in the presence of potassium butylate (7) in reaction with vinyl acetate (2) have formed vinyl esters of corresponding aromatic carboxylic acids (5a-o). The electronic effect of the substitutor in the aromatic ring affects on carrying out of the reaction and the nature of obtained products. The structure of the synthesized vinyl esters of aromatic carboxylic acids was confirmed by FT-IR, 1H_NMR, 13C-NMR, and LC/MS spectral analysis, and some of their physical constants were determined.
