摘要：

The reaction of Me2Al[N(2-C5H4N)Ph], 1. with 1 equiv. (Me3Si)(2)NLi affords the lithium aluminate Me2Al[N(SiMe3)(2)][N(2-C5H4N)Ph]Li, 2, which exhibits solvent dependent reactivity towards oxygen. In toluene 2 appears to resist oxygenation but in the presence of THF it reacts to afford the new complex [Me2AlN(2-C5H4N)-Ph](2)(O)Li-2. 2THF-, 3. X-Ray diffraction data reveal that 3 has a butterfly-type Al2Li2 bimetallic core with two equivalents of reformed 1 stabilising discrete, molecular lithium oxide. The structures of 1-3 are probed theoretically.
