The purpose of the work was to establish the influence of the chemical composition and physicochemical characteristics of composites of metal-containing N-doped carbon nanoparticles and porous media on the catalytic properties of such systems in the reaction of amination of aromatic aldehydes and ketones with primary and secondary amines in the presence of hydrogen, as well as in the development of palladium composites. which have high catalytic performance in the processes of amination of carbonyl compounds with amines in the presence of hydrogen. The structure of a series of new composites obtained by pyrolysis of complex compounds of cobalt(II) with 1,2-diaminobenzene, imidazole, 1,10-phenanthroline, melamine, 1,2-diaminobenzene, and thiosemicarbazone of 2-furancarbaldehyde on porous supports of different nature was studied in the work - aerosils and NaX zeolites, as well as composites obtained by thermolysis of the palladium(0) complex with dibenzoylacetone in the presence of activated carbon. The resulting composites contained metallic cobalt nanoparticles and graphene-like carbon particles doped with nitrogen or palladium nanoparticles. The phase composition and size of metal nanoparticles were estimated by X-ray phase analysis and confirmed by TEM. The presence of amorphous carbon in cobalt-containing composites is confirmed by elemental analysis data of the composite and Raman spectroscopy data. Amination of substituted benzaldehydes with amines in the presence of synthesized cobalt composites leads to the formation of secondary amines with yields ranging from 50 to 95% under elevated pressure, and in the presence of developed palladium composites, a quantitative yield in amination is achieved at a pressure of 1 atm a Product Description popup.authors Asaula Vitaliy Mykolayovich Boichuk Tetiana M.
