20.500.12556/RUL-137984 Sinteza in karakterizacija rutenijevih koordinacijskih spojin z izbranimi škorpionatnimi ligandi Synthesis and characterization of ruthenium complexes with selected scorpionate ligands Namen magistrske naloge je bil poiskati primerno sintezno pot za pripravo koordinacijskih spojin rutenija z izbranimi škorpionatnimi ligandi, raziskati kemizem koordinacije škorpionatnih ligandov s spreminjanjem sinteznih pogojev ter dobiti produkte v čim bolj čisti, kristalinični obliki in s čim večjim izkoristkom. V okviru magistrske naloge sem sintetizirala dva različna škorpionatna liganda natrijev tris(metimazolil)hidroborat in tris(1-metil-imidazol-2-iltio)metan ter šest rutenijevih kompleksov. Kot prekurzor sem uporabila organorutenijev prekurzor [(η6-p-cimen)RuCl2]2 oz. njegov analog z bromom. Pri sintezi kompleksov sem uporabila različne ligande: bis(3,5-dimetilpirazol-1-il)etanojsko kislino, natrijev tris(metimazolil)hidroborat in tris(3,5-dimetil-pirazolil)hidroborat. Posamezne sintetizirane produkte sem po potrebi očistila s kolonsko kromatografijo ter jih analizirala z NMR in IR spektroskopijo in masno spektrometrijo. Kristalinične produkte sem proučevala tudi z rentgensko strukturno analizo. The purpose of my Master thesis was to find a suitable synthetic route for the preparation of coordination compounds of ruthenium with selected scorpionate ligands, to investigate the coordination chemistry of scorpionate ligands by varying the synthesis conditions and to obtain the products in the purest, crystalline form and in the highest possible yield. In the framework of my Master thesis I synthesised two different scorpionate ligands: sodium tris(methimazole)hydroborate and tris(1-methyl-imidazole-2-ylthio)methane, as well as six ruthenium complexes. As a precursor I used the organoruthenium precursor [(η6-p-cymene)RuCl2]2 or its bromine analogue. In the synthesis of the complexes I used different ligands: bis(3,5-dimethylpyrazol-1-yl)acetic acid, sodium tris(methimazole)hydroborate and tris(3,5-dimethylpyrazolyl)hydroborate. The individual synthesised products were purified by column chromatography and analyzed by NMR, IR spectroscopy and mass spectrometry, as appropriate. I also studied the crystalline products by X-ray structural analysis. rutenij škorpionatni ligandi koordinacijske spojine ruthenium scorpionate ligands coordination compounds true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2022-07-07 09:55:00 2022-07-07 09:55:02 2022-09-15 04:16:08 0000-00-00 00:00:00 2022 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 10241 117037571 Rebernik_Mihaela_-_Sinteza_in_karakterizacija_rutenijevih_koordinacijskih_spojin_z_izbranimi_sko.pdf Rebernik_Mihaela_-_Sinteza_in_karakterizacija_rutenijevih_koordinacijskih_spojin_z_izbranimi_sko.pdf 1 D9E63770B95D0CB2E36BB618DFB33E35 e6865a0ada791b555fd58aafa3dabcb6e84af4ec9149af58ffa31e6138412f01 e2cebce7-fdc9-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158118 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
