摘　　要：通过桥连双β-二酮类化合物与取代苯胺反应,合成了5个新的桥连双（β-单酮亚胺）化合物（1-5）和2个新的桥连双（β-二酮亚胺）化合物（6,7）,它们与三甲基铝反应,得到了相应的3个双（β-酮亚胺基）二铝配合物（8-10）和2个双（β-二酮亚胺基）二铝配合物（11,12）。采用核磁共振、红外光谱和质谱等对这些化合物进行了表征,通过X射线单晶衍射分析证实了铝配合物的结构,并考察了这些铝配合物在ε-己内酯开环聚合反应中的催化活性。Owing to its special physical and chemical properties as well as good coordination activity with transition metals, β-diketone-derived β-ketimines and β-diketimines have been extensively studied in recent years. In this work, five new bridged bis（β-ketimine）（1-5） and bis（β-diketimine） ligands（6,7） were syn-thesized by the condensation reaction of 3,3＇-（1,4-phenylene） bis（2,4-pentanedione） with various anilines. Treatment of these ligands with AlMe3 afforded five new aluminum complexes（8-12）. All these compounds were characterized via elemental analysis, 1 H NMR, 13 C NMR, ESI-MS and IR spectroscopy. Structures of two aluminium complexes were determined by the X-ray single-crystal diffraction analysis. The bridged β-keti-mine acted as a chelating N, O-bidentate ligand to the aluminium atom. Each aluminum atom showed a dis-torted tetrahedral coordination geometry. These aluminum complexes exhibited effective catalytic activity in the ring-opening polymerization of ε-caprolactone.
