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), X-ray diffraction study. Results of the research are the synthesis of carbenes and carbenoids including palladium carbene complexes with sterically shielded branched aromatic substiuents contain additional aromatic groups (biphenylyl, naphtyl, etc), mesoionic palladium complexes with sterically shielded substiuents. A monomeric carbene and palladium carbene complex structures with branched aromatic substiuents were found by the method of X-ray diffraction study. The catalytic action of some synthesized carbene complexes of transition metals was studied for the reaction of haloarene hydrodehalogenation (hexachlorobenzene). The enhanced efficiencies for he complexes with additional aryl groups were achieved for the reaction (TON up to 240000, TOF up to 10000 h Product Description popup.authors Глиняна Наталія Валеріївна Кисельов Артем Вікторович Короткіх Микола Іванович Швайка Олесь Павлович popup.nrat_date 2020-04-02 Close
