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.Synthesis and structures of [((Me3Si)(3)CAlF2)(2)(mu-O)Li-2(THF)(4)] and [{Li(Me3Si)(3)CAlF3(THF)}(3)LiF(THF)]journal_article10.1021/om0100941000169242700036
