Research methods - NMR, UV, IR spectroscopy, quantum-chemical calculations. Reaction of 4-methylbenzene sulfonyl chloride with phenolate ions in water-dichloromethane medium under IPTC was studied. Catalyzed rate constants of sulfonylation reaction were obtained. Their dependence on basicity catalyst was found. The most efficient catalyst was determined. It is shown that the IPTC method is promising for synthesis of sulfonic acid esters. Methods of IR, NMR spectroscopy and DFT were used to found out structures of a number of sulfonic acid esters. NMR, UV, IR spectroscopy and quantum chemistry were used to study the structures and tautomeric equilibria of a number of gossypol imine derivatives. It was shown that gossypol Schiff bases exist in enamine-enamine form and hydrazones - in imine-imine form irrespective of solvent. The researches were necessary for the improvement and development of the theory of inverse phase-transfer catalysis and important in terms of "green chemistry". Since the aim was to study the reactivity of organic compounds in water and obtaining new useful substances using natural renewable raw materials.
