摘要：

Reactions of the organotrihydroaluminate Li-[(Me(3)Si)(3)CAlH3]. 2THF, (THF = tetrahydrofuran) with the protic reagents (t)BuOH or HF in toluene yield the novel compounds Li[(Me(3)Si)(3)CAlX(3)]. THF, X = (t)BuO or F, which crystallize as a monomer and a tetramer, respectively. Multinuclear NMR measurements on the latter show that the tetrameric structure is broken down in THF but preserved in benzene; the [(Me(3)Si)(3)CAlF3] fragments rotate on the NMR time scale about the body diagonal of the Al4Li4 cube.
