An aim of the study is an improvement of the carbene complex new-generation catalysts to improve their efficiency in the reaction of haloarene hydrodehalogenation. Methods of the study are synthetic, spectral (NMR spectroscopy), analytical (chromatography, elemental analysis). Results of the research are the synthesis of the new sterically shielded salt carbenoids with diisopropylphenyl, 4-alkyl-bis (2,6-dibenzhydrylmetyl) phenyl, 4-methyl-2,6-bis-(4-phenyl-4-diphenylylmethyl)phenyl, 4-methyl-2,6-bis (phenyl-1-naphthylmethyl)phenyl groups, some carbenoid precursors of a new type. New sterically complicated mesoionic compounds (imidazol-4-ids and 1,2,3-triazol-5-ids) were synthesized as ligands for palladium carbene complex compounds. The catalytic effect of some synthesized transition metal carbene complexes was studied in haloarene (hexachlorobenzene) hydrodehalogenation. It has been shown that the efficiency of two complexes reaches the new generation catalysts synthesized (TON 320000, TOF 13330 h Product Description popup.authors Глиняна Наталія Валеріївна Кисельов Артем Вікторович Короткіх Микола Іванович Швайка Олесь Павлович popup.nrat_date 2020-04-02 Close
