  Lightest Member of the Basic Carboxylate Structural Pattern:  [Al₃(μ₃-O)(μ-O₂CCF₃)₆(THF)₃][(Me₃Si)₃CAl(O₂CCF₃)₃]·C₇H₈

  摘要：

  [Al-3(mu(3)-O)(mu-O2CCF3)(6)(THF)(3)][(Me3Si)(3)CAl( OC(O)CF3)(3)]-C7H8 is the first characterized mu3-oxo-trinuclear basic carboxylate of aluminum closing the gap of isomorphism with the transition metal analogues. The system is an excellent case study for the electronic structure approached by DFT-B3LYP calculations. The actual system proves that the oxo-trinuclear pattern is stabilized by the chemical hardness of oxygen donors and by highly symmetric intramolecular packing of the ligands.

  bulky tris(trimethylsilyl)methyl group substituted aluminum trialkyl [(Me3Si)3CAlMe2·THF] (1) with a series of substituted benzoic acid derivatives has been investigated. An equimolar reaction of 4-methyl benzoic acid or 4-tert-butyl benzoic acid with 1 in toluene at 50 °C leads to the formation of cyclic dimeric aluminum carboxylates [(Me3Si)3CAl(Me)(μ-O2CC6H4R)]2 (R = Me 2; tBu 3).

  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.
