Purpose - to develop methods of condensation of carboxylic acids chlorides with phenols and diphenols in two-phase systems water-organic solvent with the presence of pyridine N-oxides, the catalyst influence on reaction rate and yield study, the most effective catalyst determination and conditions of esters synthesis optimization. Physico-chemical properties and structure obtained compounds studying. Research methods - infrared spectroscopy, nuclear magnetic resonance, elemental analysis, quantum-chemical calculations. Were studied inverse phase transfer catalysis (CTI) reactions of phenols benzoylation. It is shown that use of CTI allows monophenols and diphenols benzoylation reaction make under mild conditions. The influence of the initial concentration of the catalyst in aqueous phase on the rate of reaction and product yeld was found. It was found that the most efficient catalyst among subjects for benzoylation reactionis 4-dimethylaminopyridine-N-oxide. The structure of six ethers: -4- nitrophenylbenzoate, 4- cyanophenylbenzoate, 2 formil-3,5-dimethoxyphenylbenzoate, 2-methylhinolin-4-olbenzoate, p-phenylenedybenzoate, m-phenylenedybenzoate, naphthalene-2,3-dioldybenzoate. The new gossypol imine derivatives were synthesized. The structure and tautomeric equilibrium by methods IR and NMR spectroscopy were studied. The novelty of the work is in developing simple environmentally sound methods phenols benzoylation.
