While perfluorinated aryl, aryloxy and alkoxy aluminum species are well-established as weakly coordinating anions (WCAs), corresponding perfluoroalkyl aluminum derivatives are virtually unknown. Reaction of Si(C F ) CH with Li[AlH ] afforded the tetrakis(pentafluoroethyl)aluminate, [Al(C F ) ] . Several salts of the [Al(C F ) ] ion were synthesized and characterized by NMR spectroscopic methods, mass spectrometry, X-ray diffraction studies and elemental analysis.
虽然全氟芳基、芳氧基和烷氧基铝物种作为弱配位阴离子（WCA）已得到充分确立，但相应的全氟烷基铝衍生物实际上却鲜为人知。Si(CF₃)₃CH与Li[AlH₄]反应得到四(五氟乙基)铝酸盐[Al(C₂F₅)₄]⁻。合成了几种[Al(C₂F₅)₄]⁻离子的盐，并通过核磁共振光谱法、质谱法、X射线衍射研究和元素分析对其进行了表征。
