20.500.12556/RUL-127616 Koordinacijske spojine z N-etoksikarbonil-N'-(3-metilpiridin-2-il)tiosečnino kot ligandom Coordination compounds with N-ethoxycarbonyl-N'-(3-methylpyridine-2-yl)thiourea as ligand Izvedla sem reakcije med N-etoksikarbonil-N'-(3-metilpiridin-2-il)tiosečnino kot ligandom in Cu(II), Ni(II), Cd(II), Zn(II) ter Co(II) ioni ter z dodatkom MeONa in/ali KSCN v reakcijski zmesi. Reakcije so potekale v metanolu kot topilu ob segrevanju in intenzivnem mešanju. Nastalo je šest različnih produktov. Reakcije Cd(II), Zn(II) in Co(II) z ligandom niso potekle. Ligand pa se je uspešno koordiniral na Ni(II) in Cu(II) ione. Pri reakcijah s Cu(II) ioni in ligandom sta poleg koordinacijske spojine nastali še dve spojini, kjer je prišlo do oksidativne ciklizacije liganda in je nastal 2-((etoksikarbonil)amino)-8-metil-[1,2,4]tiadiazolo[2,3-a]piridin-4-ijev kation. Nastale produkte sem okarakterizirala z IR spektroskopijo, 1H NMR spektroskopijo, rentgensko strukturno analizo in elementno analizo. Reactions between N-etoxycarbonyl-N'-(3-methylpyridine-2-yl)-thiourea, as ligand, and Cu(II), Ni(II), Cd(II), Zn(II) and Co(II) ions with addition of MeONa and/or KSCN were performed. The reactions were carried out in methanol as solvent, with heating and vigorous stirring. Six different products were created. Reactions between Zn(II), Co(II), Cd(II) ions and ligand did not occur. The ligand was successfully coordinated to Ni(II) and Cu(II) ions. Reactions with Cu(II) ions and the ligand, alongside to the coordination compound, two other compounds were formed, where oxidative cyclization of the ligand occurred and 2-((ethoxycarbonyl)amino)-8-methyl-[1,2,4]thiadiazolo[2,3-a]pyridin-4-ium cation was formed. The resulting products were characterized by IR spectroscopy, 1H NMR spectroscopy, X-ray structural analysis and elemental analysis. tiosečnina ligand N-etoksikarbonil-N'-(3-metilpiridin-2-il)tiosečnina oksidativna ciklizacija koordinacijske spojine thiourea ligand N-etoxycarbonyl-N'-(3-methylpyridine-2-yl)-thiourea oxidative cyclization coordination compoud true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2021-06-16 14:55:01 2021-06-16 14:55:07 2022-09-06 03:52:16 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 9662 69566211 Virant_Petra_-_Koordinacijske_spojine_z_N-etoksikarbonil-N_-(3-metilpiridin-2-il)tiosecnino_kot_.pdf Virant_Petra_-_Koordinacijske_spojine_z_N-etoksikarbonil-N_-(3-metilpiridin-2-il)tiosecnino_kot_.pdf 1 A736867095E3F22B07BE2A609945CA42 ee8d0e92e1e1881b115aa850df49a67d406b5e4cef693e24e1ad1c7c050b0b4b fa398f89-cea1-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144070 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
