摘要：
The alkyltrihydroaluminate [Li(thf)(2){AlH3[C(SiMe3)(3)]}](2), (thf = tetrahydrofuran) reacted (i) with tetramethylethane-1,2-diamine (tmen) to give [Li(tmen)(2)][AlH3{C(SiMe3)(3)}], which crystallises as solvent-separated ion pairs, (ii) with HCl, HBr or Br-2, or I-2 to give, respectively, the alkylaluminium dihalides [AlX2{C(SiMe3)(3)}].thf, X = Cl, Br or I, which have been characterised spectroscopically and, when X = Br or I, by X-ray diffraction studies; and (iii) with aniline to give [Li(thf)(2)(mu-NHPh)(2)(AlH[C(SiMe3)(3)]}] and [Li(thf)(4)][Al(NHPh)(3){C(SiMe3)(3))], which crystallise as anilide-bridged and solvent-separated ion pairs respectively.
