Resumo: | This Thesis aimed the synthesis of new metal complexes with triazenido ligands and triazenes chains directly linked to ferrocene fragment by a new synthesis methodology. The complex bis-[1,3-bis(2-biphenyl)triazenido-κN1]mercury(II) was synthesized, melting point 222–224 °C and yield 82 %, characterized by IR, UV-Vis, 1H e 13C RMN, elemental analysis, mass spectrometry by ESI(+)TOF, single crystal x-ray diffraction. The triazenes 1,1’-bis[1-phenyl-3(H)triazene]ferrocene (Compound 1) and 1,1’-bis(benzo-1,2,3-triazol-1-phenyltriazene)ferrocene (Compound 6) were synthesized by ferrocene metalation with BuLi and substitution by correspondent azide, with yields higher than 70 %, melting points 151 and 160 °C, respectively, were characterized by UV-Vis (Compound 1), 1H and 13C NMR, elemental analysis, IE-MS (Compound 1) ESI(+)TOF (Compound 6), single crystal x-ray diffraction (Compoound 1), powder x-ray diffraction, scanning electron microscopy (SEM) and thermogravimetric analysis. Starting from Compound 1 the following heterobimetallic complexes were sinthesized: {[Fe(C5H4NNNH5C6)]2Ni2} (Compound 2), {[Fe(C5H4NNN(H)H5C6)]2Cl2Cu2} (Compound 3 with protonated triazene), {[Fe(C5H4NNNH5C6)]2[Cu(PPh3)2]2} (Compound 4), {[Fe(C5H4NNN(H)H5C6)]2Cu4} (Compound 5). Compounds 6 and 7 didn’t yields suitable single crystals for X-ray diffraction, but based on the MS-ESI(+)TOF and 1H NMR analysis the respective structures based on 1,1’-bis[1-phenyl-3(H)triazene]ferrocene could be predicted. The new triazenes synthesis by methodology under study showed good yields and can be done in two steps. The compounds purification is simple by only extraction with organic solvent and water precipitation followed by filtration enabling the development of further new triazenes including other metallocenes and other azides. |

Foi sintetizado o complexo bis-[1,3-bis(2-bifenil)triazenido-κN1]mercúrio(II) com ponto de fusão 222–224 °C e rendimento de 82 %, caracterizado por infravermelho, UV-Vis, 1H e 13C RMN, análise elementar, espectroscopia de massas por ESI(+)TOF, difração de raios X em monocristal. Os triazenos 1,1’-bis[1-fenil-3(H)triazeno]ferroceno (Composto 1) e 1,1’-bis(benzo-1,2,3-triazol-1-feniltriazeno)ferroceno (Composto 6) foram sintetizados por metalação via BuLi, seguida da substituição pela azida correspondente com rendimentos superiores a 70 %, com pontos de fusão de 151 e 160 °C, respectivamente, foram caracterizados por UV-Vis (Composto 1), 1H e 13C RMN, análise elementar, espectroscopia de massas por IE (Composto 1) ESI(+)TOF (Composto 6), difração de raios X em monocristal (Composto 1), difração de raio X de pó, microscopia eletrônica de varredura e análise termogravimétrica. A partir do Composto 1 foram sintetizados os complexos multinucleares: {[Fe(C5H4NNNH5C6)]2Ni2} (Composto 2), {[Fe(C5H4NNN(H)H5C6)]2Cl2Cu2} (Composto 3 com triazeno protonado), {[Fe(C5H4NNNH5C6)]2[Cu(PPh3)2]2} (Composto 4), {[Fe(C5H4NNN(H)H5C6)]2Cu4} (Composto 5). O Composto 6 e o Composto 7 não resultaram em cristais adequados para medida, com as análises por EM-ESI(+)TOF e 1H RMN pode-se fazer uma predição da estrutura baseada nas estruturas com o 1,1’-bis[1-fenil-3(H)triazeno]ferroceno. A síntese de novos triazenos pela metodologia estudada possui bom rendimento e é realizada em apenas duas etapas, a purificação dos triazenos é simples, envolvendo apenas a extração com solvente orgânico e a precipitação em água seguida de filtração possibilitando o desenvolvimento de novos triazenos com outros metalocenos e outras azidas.Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e ExatasHörner, Manfredohttp://lattes.cnpq.br/8922528250830998Nunes, Fabio Souzahttp://lattes.cnpq.br/7117607785614286Squizani, Fatimahttp://lattes.cnpq.br/1060502818943139Bresolin, Leandrohttp://lattes.cnpq.br/3961672079507969Martins, Marcos Antonio Pintohttp://lattes.cnpq.br/6457412713967642Paraginski, Vanessa Teixeira Kunz2018-02-14T13:22:12Z2018-02-14T13:22:12Z2016-01-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/12416porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2018-02-14T13:22:12Zoai:repositorio.ufsm.br:1/12416Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2018-02-14T13:22:12Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
