Please always quote using this URN: urn:nbn:de:bvb:20-opus-214666
- Salts of the tetrakis(pentafluoroethyl)aluminate anion [Al(C\(_{2}\)F\(_{5}\))\(_{2}\)]\(^{-}\) were obtained from AlCl\(_{3}\) and LiC\(_{2}\)F\(_{5}\). They were isolated with different counter‐cations and characterized by NMR and vibrational spectroscopy and mass spectrometry. Degradation of the [Al(C\(_{2}\)F\(_{5}\))\(_{4}\)]\(^{-}\) ion was found to proceed via 1,2‐fluorine shifts and stepwise loss of CF(CF\(_{3}\)) under formation of [(C\(_{2}\)F\(_{5}\))\(_{4-n}\)AlF\(_{n}\)]− (n=1–4) as assessed by NMR spectroscopy and massSalts of the tetrakis(pentafluoroethyl)aluminate anion [Al(C\(_{2}\)F\(_{5}\))\(_{2}\)]\(^{-}\) were obtained from AlCl\(_{3}\) and LiC\(_{2}\)F\(_{5}\).

In addition, the [(C\(_{2}\)F\(_{5}\))AlF\(_{3}\)]\(^{-}\) ion was structurally characterized.…
