Salts of the tetrakis(pentafluoroethyl)aluminate anion [Al(C F ) ] were obtained from AlCl and LiC F . They were isolated with different counter-cations and characterized by NMR and vibrational spectroscopy and mass spectrometry. Degradation of the [Al(C F ) ] ion was found to proceed via 1,2-fluorine shifts and stepwise loss of CF(CF ) under formation of [(C F ) AlF ] (n=1-4) as assessed by NMR spectroscopy and mass spectrometry and supported by results of DFT calculations. In addition, the [(C F )AlF ] ion was structurally characterized.
四(五氟乙基)铝酸根阴离子[Al(CF) ]的盐通过 AlCl 和 LiCF 得到。它们与不同的抗衡阳离子分离，并通过 NMR 和振动光谱以及质谱法进行了表征。通过 NMR 光谱和质谱法评估并通过 DFT 计算结果支持，发现[Al(CF) ]离子的降解通过 1,2-氟原子迁移和 CF(CF )的逐步损失进行，形成(CF)AlF 。此外，还对[(CF)AlF ]离子进行了结构表征。
