Borodkin Y. Bis(1,1-dihydropolyfluoroalkyl)sulfides, bis(2-fluoro-2-polyfluoroalkylvinyl)sulfides and bis(polyfluoroalkylacetylenyl)sulfides. Synthesis and chemical properties.

The dissertation is devoted to the development of methods for the synthesis and investigation of chemical properties of bis(1,1-dihydropolyfluoroalkyl)sulfides, bis(2-fluoro-2-polyfluoroalkylvinyl)sulfides and bis(polyfluoroalkylacetylenyl)sulfides and their derivatives. Symmetric bis(polyfluoroalkyl)sulfides and sulfones are almost not represented in the literature, despite the relatively simple structure of molecules in these classes. Methods for the synthesis of new types of fluorine-containing sulfur derivatives - bis(1,1-dihydropolyfluoroalkyl)sulfides and sulfones have been developed. The study of the chemical properties of these compounds allowed us to establish the basic pattern’s of the reaction of their dehydrofluorination. Polyfluoroalkyl-containing heterocyclic compounds of classes such as 1,4-oxathiin-4,4-dioxide derivatives, 2,3-dihydro-1,4-oxathiines, 1,4-oxathian, bis(pyrazolyl)sulfones, bis(triazolyl)sulfones were synthesized and have not been presented in the literature before. The reactivity of the obtained heterocycles was studied. Bis(3,3,4,4,5,5,6,6,7,7,8,8-dodecafluorooct-1-yn-1-yl)sulfide was also obtained for the first time. The results of X-ray structural studies for representatives of almost all types of the obtained compounds are presented.
