摘要：

The preparation of lithium tris(dimethylamino)silylamide, [(Me3N)(3)SiNHLi](4), 2, and its reaction with aluminium trichloride to give tris(dimethylamino)silylamino)(tetrahydrofuran)alane, (C4H8O)Al[NHSi(NMe2)(3)](3), 3, and bis(tetrahydrofuran)lithium tetrakis(tris(dimethylamino)silylamino)alanate, Li(THF)(2) (+)[((Me2N)(3)SiNH)(4)Al](-), 6, is reported, together with the crystal structures of 2, 3 and 6. Tris(dimethylamino) alane, ((Me2N)(3)SiNH)(3)Al, was obtained by reaction of tris(dimethylamino)silylamine with aluminium triethyl. The ammonolytic gelation of 3 to an imidoaluminosilicate gel is also described.
