Sulfenes, their structure and reactions. The goal of the work is the synthesis of new types of transition metal carbene complexes of polymeric and calixarene series; the study of catalysis for the reactions of multiple bond reduction, amination and dehalogenation of halogenarenes; the study of the reactions of sulfenes with activated ketones. Methods for the study are synthetic, kinetic, spectral (NMR spectroscopy), analytical (chromatographic and elemental analysis), quantum chemical. Results: synthesis of new carbene complexes of copper and palladium of polymer type was carried out on the basis of crowncarbene and related macrocyclic salts and salts of transition metals; new tetraimidazolylmetyl- and tetraimidazoliometylcalix[4]arenes were obtained under the action of imidazole to tetrachlorometylcalix[4]arene; the interactions of these carbenoids with palladium acetate lead to tetracarbene complexes of palladium. It was found that the reactions of sulfenes with 2- arylidenamino-1,3-thiazoles activated by electronwithdrawing substituents, depending on the structure of sulfenes and carbonyl compounds, lead to the isomeric 1,3-thiazole-tiadiazine-S, S-dioxides, beta - and gamma-sultones, functionally-substituted alkylsulfonic acids and vinylmezylates that opens up prospects for their use in organic synthesis.
