  摘要：

  Interaction of [AlH3(NMe3)] and [AlH2Cl(NMe3)] with HOR1 (R1 = C6H2But2-2,6-Me-4) allows for the isolation of [AlH2(OR1)(NMe3)] 1 and [Al(H)Cl(OR1)(NMe3)] 2 respectively. Compound 1 exists in both mono- and di-meric forms in the solid state. The reaction of 1 with NH2But results in ligand redistribution to give [AlH(OR1)2(NH2But)] 3. Similarly, multiple recrystallisation of 1 from Et2O allows for the isolation of [AlH(OR1)2(OEt2)] 4, while addition of HOR2 (R2 = C6H3Ph2-2,6) to 1 yields the mixed aryloxide complex [AlH(OR1)(OR2)(NMe3)] 5. Interaction of compound 1 with benzophenone results in the formation of the bridged dimer [{AlH(OR1)(mu-OCHPh2)}2] 6. The reaction of 3 molar equivalents of HOR1 with LiAlH4 yields, in addition to [{Li(OR1)(OEt2)}2], compound 4, which reacts further with H2O, HOR1 or NH2C6H2Cl3-2,4,6 to give [{Al(mu-OH)(OR1)2}2] 7, [Al(OR1)3] 8 or [Al(OR1)2(NHC6H2Cl3-2,4,6)] 13 respectively. Compounds 8 and 13 form stable Lewis acid-base complexes [Al(OR1)3L] [L = MeCN 9, pyridine (py) 10, O=PPh3 11 or O=C(C5H9)But-4 12] and [Al(OR1)2(NHC6H2Cl3-2,4,6)L] (L = Et2O 14, py 15 or 3,5-dimethylpyridine 16). The presence of a slow ligand exchange for compounds 9 and 12 was investigated by H-1 NMR spectroscopy. The molecular structures of 1, 3, 4, 8 and 12 have been confirmed by X-ray crystallography.
