Master Thesis Reactions of Oxomolybdenum Compounds With Nitrogen Donor Ligands and Related Computational Calculational Calculations(Izmir Institute of Technology, 2009) Öcal, Jale; Sözüer, Işıl; Topaloğlu Sözüer, Işıl; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of TechnologyReactions of the dioxomolybdenum(VI) compound, MoCl2O2 with phenylenediamine derivatives the bidentate N-N nitrogen ligands 1-8 (ophenylenediamine, N-phenyl-o-phenylenediamine, 4-Methyl-o-phenylenediamine, 4-Nitro-o-phenylenediamine, p-phenylenediamine, N-phenyl-p-phenylenediamine, 2,6- dichloro-p-phenylenediamine, 2,3,5,6-tetramethyl-p-phenylenediamine, respectively) have been examined under nitrogen in THF solution. The novel dioxomolybdenum complexes were characterized by elemental analysis, FT-IR, 1H-NMR and 13C-NMR spectroscopy. In addition, molecular mechanics and quantum chemical calculations including semi empirical PM3 and DFT methods were carried out to discuss the stability of the compounds.Master Thesis Snythesis and Spectroscopic Characterization of Some New [tris (3,5-Dimethyl Borato] Molybdebum Complexex(Izmir Institute of Technology, 2003) İrdem, Seçkiner Dülger; Sözüer, Işıl; Topaloğlu Sözüer, Işıl; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of TechnologyIn this study, the new binuclear oxo bridged imido Mo(V) complexes [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4X)], (p-X = Cl, Br) and [MoTp*(O)Cl](µ-O) [MoTp*(Cl)(≡NC6H4Y)], (m-Y = I, F) have been synthesized by the reaction oxo molybdenum (V) precursor [MoTp*(O)Cl2]; [Tp* = Tris(3, 5-dimethyl-pyrazol)borato] with p- and m- functionalized anilines, H2NC6H4X and H2NC6H4Y (p-X = Cl, Br; m-Y=I, F) in toluene solution. The complexes have been characterised by 1 H-NMR, IR spectroscopy and FABMassspectrometry. The structures of [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4X)], (p-X = Br) and [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4Y)], (m-Y = I, F) have been characterised by X-Ray diffaction method.Master Thesis Synthesis, Characterization and Computational Studies of Oxomolybdenum Compounds With Nitrogen Donor Ligands(Izmir Institute of Technology, 2010) Kıyak, Harika; Sözüer, Işıl; Topaloğlu Sözüer, Işıl; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of TechnologyIn the first part of the project, the reactions of the solvent-stabilized compound [MoO2Cl2(THF)2] with varios phenylenediamine and some napthalenediamin derivatives in THF at room temperature were investigated. These reactions yielded mononuclear and dinuclear compounds of the type [MoO2Cl2L] and [Mo2O3(.2- O)Cl4(L)2] respectively. In the second part, the reactions of [Mo2O3Cl4(DMF)4] with phenylenediamine and napthalenediamin derivatives were studied under similar conditions and Mo-O-Mo bridged dinuclear oxomolybdenum compounds of the type [Mo2O3(.2-O)Cl4(L)] were obtained. The new compounds were comparatively examined by elemental analysis, FTIR, 1H-NMR and 13C-NMR techniques. In addition, quantum chemical calculations including semi empirical PM3 and DFT methods were carried out to discuss the stability and geometry of the compounds.Master Thesis Synthesis and Characterization Oxo-Imido [tris (3,5-Dimethyl Borate] Molybdenum Complexes(Izmir Institute of Technology, 2004) Şahin, Engin; Sözüer Topaloğlu, Işıl; 01. Izmir Institute of TechnologyIn this study two new reactions related to oxo-Molybdenum(V)trispyrazolyl chemistry were investigated. The reactions between [MoTp*(O)Cl2] with o-substituted anilines, H2NC6H4X-o (X. Cl, Br) in the presence of triethylamine in toluene carried out to prepare dinuclear oxo-imido Mo(V) complexes of the type [MoTp*(O)Cl](.-O)[MoTp(Cl)(.NC6H4X-o)]. Surprisingly, the previously reported compound, [MoTp*(O)Cl]2(.-O)], was obtained as the major product of both reactions. The compound [MoTp(O)Cl]2(.-O)] was characterized by 1H-NMR; IR, UV-visible spectroscopy techniques.
