Synthesis and Characterization of Tetrakis(pentafluoroethyl)aluminate

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(2)F(5))(3)CH(3) with Li[AlH(4)] afforded the tetrakis(pentafluoroethyl)aluminate, [Al(C(...

Sumario: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(2)F(5))(3)CH(3) with Li[AlH(4)] afforded the tetrakis(pentafluoroethyl)aluminate, [Al(C(2)F(5))(4)](−). Several salts of the [Al(C(2)F(5))(4)](−) ion were synthesized and characterized by NMR spectroscopic methods, mass spectrometry, X‐ray diffraction studies and elemental analysis.
