Synthese, Charakterisierung und Eigenschaften neuartiger Mono- und Bis-Pentafluorethylborate sowie Pentafluorethylboran-Addukte / Synthesis, characterisation and propterties of new mono- and bis-pentafluoroethylborates as well as pentafluoroethylborane-adducts

Hennig, Philipp Thomas January 2022 (has links) (PDF)
Diese Arbeit beschäftigt sich mit der Synthese, Charakterisierung und Eigeschaften neuer Monopentafluorethylborat-Anionen der Form [C2F5BH2X]- (X= F, Cl, Br), [C2F5BH2(CN)]-, [C2F5BH(CN)2]-, [C2F5BH(CN)X]- (X= F, Cl, Br) und [C2F5B(CN)X2]- (X= Cl, Br)sowie den Bis-pentafluorethylborat-Anionen [(C2F5)2B(OMe)(CN)]-, [(C2F5)2BF(CN)]- und [(C2F5)2B(CN)2]-. Von einigen dieser Verbindungen wurden Ionische Flüssigkeiten basierend auf dem 1-Ethyl-3-methylimidazolium-Kation synthetisiert und deren physikalischen Parameter ausführlich untersucht. Zudem wurden Pentafluorethylboran-Addukte mit verschiedenen Lewis-Basen der Form C2F5BH2-L (L= THF, SMe2, CH3CN, Pyridin, PPh3, CAAC, IDipp, SIDipp, Me4Im, (iPr)2Me2Im, tBu2Im) hergestellt welche zum Teil als Startmaterialien für die Synthese von Monopentafluorethylboraten verwendet wurden. / In this work, syntheses, characterisation and properties of new monopentafluoroethylborate anions like [C2F5BH2X]- (X= F, Cl, Br), [C2F5BH2(CN)]-, [C2F5BH(CN)2]-, [C2F5BH(CN)X]- (X= F, Cl, Br) and [C2F5B(CN)X2]- (X= Cl, Br) as well as bis-pentafluoroethylborate anions [(C2F5)2B(OMe)(CN)]-, [(C2F5)2BF(CN)]- and [(C2F5)2B(CN)2]- are presented. Furthermore, several of these compounds were transformed into Ionic Liquids by isolation of the corresponding 1-ethyl-3-methylimidazolium salt and their physical propterties were studied in detail. Besides, pentafluoroethylborane adducts with different lewis bases like C2F5BH2-L (L=thf, SMe2, CH3CN, pyridin, PPh3, CAAC, IDipp, SIDipp, Me4Im, (iPr)2Me2Im, tBu2Im) were synthesized which turned out to be good starting materials for the synthesis of monopentafluoroethylborates.
