Khmelnitsky state university in Cherkasy popup.description2 The discovery of new limits for the usage of preparative already known chemical reactions and synthesis of materials with practically useful properties are priority area of researches in organic chemistry. Steady chemists interest for the discovered by Meerwein reaction can be explained by existing in it a wide range of external factors that affect the structure of final products. The object of research are anionarylation reactions of unsaturated systems containing one or two isolated multiple carbon-carbon bonds; the anionarylsulfonation reaction of the unsaturated compounds with two isolated multiple carbon-carbon bonds; some conversion reactions of products. The subject of research are aliphatic-aromatic trisubstituted triazenes, arylsulfonyl-butadiene, and arylsulfonylisopren vinyl ether as the reagents for anionarylsulfonation reactions of unsaturated systems. One part of this project is development of some approaches to: explanation of the mechanisms of the Meerwein reaction and their modified versions; obtaining of the isoprene, butadienearylsulfones, ?-arylsubstituted alkoxy and aroxyethylidenacetates not described in the literature. To solve these problems such investigations were performed: the intercepted terms between the singlet and triplet states of phenyldiazonium cations were established; singlet-triplet (S ? T) transitions energies in substrate molecules dependence of their values with the corresponding outputs Meerwein reaction products were calculated; the influence of the complexation between catalyst and substrate on S ? T transition energy value was predicted, optimum conditions for the synthesis of 1-(p-carboxyphenylsulfonyl)-butadiene-1,3 and 1-(p-sulfophenylsulfonyl)-butadiene-1,3 and 1-arylsulfonylisoprenes, 1-butoxy-2 and 1-arylethyl-phenoxy-2-arylethylacetates were proposed. To investigate the conversion of obtained products and anionarylation and anionarylsulfonation reactions of the such unsaturated compounds. Methods of research: organic synthesis, elemental analysis, spectral methods (1H NMR, IR and chromatography-mass spectroscopy), preparative column chromatography, quantum-chemical calculations Product Description popup.authors Бондарчук Сергій Вікторович Смалиус Віктор Васильович Фесак Олександр Юрійович popup.nrat_date 2020-04-02 Close
