Formation of Very Weakly Interacting Organometallic Cation−Anion Systems Using Pearson's HSAB Concept: Synthesis and Structures of [Ag(Toluene)3]+ [{((SiMe3)3C)2Al2F5}2Li]- and [AlF2(THF)4]+ [{(SiMe3)3C}2Al2F5]-
摘要:
By using Pearson's HSAB principle [Ag(Toluene)(3)](+) [{((SiMe3)(3)C)(2)Al2F5}(2)Li](-) (2) has been synthesized from the reaction of [(SiMe3)(3)CalF(2)](3) (1) with AgF and LiCl. Reaction of 1 with AgF2 and NH4F affords [AlF2(THF)(4)](+) [{(SiMe3)(3)C}Al2F5](-) (3) and [NH4](+) [(SiMe3)(3)CalF(3)](-) (4), respectively. 2 and 3 have been structurally characterized.

The synthesis of [((Me3Si)(3)CAlF2)(2)(mu -O)Li-2- (THF)(4)] (1) and [Li(Me3Si)(3)CAlF3(THF)}(3)LiF(THF)] (2) is reported. Compound 1 was obtained either by the reaction of (Me3Si)(3)CAlMe2. THF and Me3SnF in the presence of Li2O or by the reaction of [(Me3Si)(3)CAlF2](3) and Li2O. 1 is an interesting example of an oxygen- and fluorine-containing alkyl aluminum compound. Complex 2 was prepared by the reaction of (Me3Si)(3)CAlF2. THF with LiOCH(CF3)(2) as an unexpected result that illustrates the variety of possible structures obtainable by the combination of [(Me3Si)(3)CAlF2](3) and LiF.
