Didenko N. Direct synthesis of coordination compounds of Copper(II) with thioamides of various substitution

The thesis is dedicated to direct synthesis of coordination compounds of Copper(II) with thioamides of various substitution in protic and aprotic solvents, research of their physicochemical and functional properties. Explored the influence of the oxidant, nature of the organic solvent, thioamide ligand and conditions of the obtaining of coordination compounds of Copper(II) in the system Cu - Thio - Ox - Solv. It was found, that composition and structure of the complexes of Copper(II) with thioamides of various substitution could be changed depending on the oxidant, nature of thioamide ligand, organic solvent and their stoichiometric ratio in reaction media. Developed methods of the direct synthesis of 23 coordination compounds, established their composition and structure using modern physicochemical methods. By using X-ray crystallography was explored the structure of Copper(II) complexes: [Cu(С10Н11N3S)Cl2] · (CH3)2SO, [Cu2(C32H30N6O2S2)Cl4] · 2CH3OН. Explored the influence of thioamides, their Copper(II) complexes and DMF on anti-wear and friction-reducing properties of lubricating compositions based on industrial oil I-20A in the tribochemical system "bronze - steel". It was found that the increase of the performance of lubricating compositions was determined by a forming of coordination compounds of Copper(II) during tribochemical reactions. Explored a plant growing activity of the synthesized compounds and shown a perspective of the further studying of their biological activity.
