摘　　要：β-二亚胺作为一类理想的含氮单阴离子非环戊二烯基配体,可以很好的稳定低价或配位不饱和的金属配合物,而桥联的双β-二亚胺配体要比单个β-二亚胺配体多个活性位点,会以更多的方式与金属配位,该类配合物表现出更高的催化活性和更加丰富的反应性。本文利用芳基桥联双β-二亚胺配体LH_(2)(L=[μ-(1,4-C_(6)H_(4))][N(Me)CH_(2)-CH_(2)NC(Me)CC(Me)HNDipp]_(2)^(2-),Dipp=2,6-(iPr)_(2)C_(6)H_(3))和4当量的三甲基铝反应,得到了相应的双核金属铝配合物LAl_(2)Me_(4)(1)。然后通过^(1)H NMR、^(13)C{^(1)H}NMR、红外光谱和单晶X-射线衍射对该配合物进行了结构表征。As an ideal class of nitrogen-containing monoanionic non-cyclopentadienyl ligands,β-diimide can well stabilize low-valent or coordination unsaturated metal complexes,while bridging bis(β-diketiminato)ligands have multiple active sites than a singleβ-diimide ligand,and will coordinate with metals in more ways,and such complexes exhibit higher catalytic activity and richer reactivity.In this paper,the corresponding binuclear metal aluminum complexes were obtained by the reaction of aryl-bridged bis(β-diketiminato)ligand LH_(2)(L=[μ-(1,4-C_(6)H_(4))][N(Me)CH_(2)-CH_(2)NC(Me)CC(Me)HNDipp]_(2)^(2-),Dipp=2,6-(iPr)_(2)C_(6)H_(3))and 4 equivalent trimethyl aluminum LAl_(2)Me_(4)(1).The complex was then structurally characterized by^(1)H NMR,^(13)C{^(1)H}NMR R,infrared spectroscopy,and single crystal X-ray diffraction.
