Fesun I. Fluorinated 1,2-dithiole-3-thiones

The thesis is devoted to study of chemical properties of 4-fluoro-5-polyfluoroalkylsubstituted 1,2-dithiole-3-thiones. It was shown that presence of polyfluoroalkyl substituent and fluorine atom leads to changing of reaction routes with chlorinating and reducing agents and secondary amines, in comparing with non-fluorinated analogs. It was found that chlorination leads to 3-chlorothio-1,2-dithiolium salts or polychlorinated dithiolanes. It was established that structure of products of reactions with aminocompounds depends on nature of amines as well as length of polyfluoroalkyl chain. Treatment of tetrafluoroethylsubstituted dithiolethione with sodium sulfide gives either trithiapentalenes or thiopyranethiones depends on quantity of reagents.
