摘　　要：使用Ｂａ２＋作为模板离子，将１，５－二（邻氨基苯氧基）－３－氧杂戊烷（３）分别与４－取代的２，６－二甲酰基苯酚（１ａ～１ｃ）反应，获得高收率的Ｓｃｈｉｆ碱大环配合物（４ａ～４ｃ），再经ＮａＢＨ４还原解络，得到氮杂大环自由配体（Ｌ１～Ｌ３）．本文研究和改进了４－取代的２，６－二甲酰基苯酚（１ａ～１ｃ）的合成方法，由４－取代的２，６－二羟甲基苯酚经活性ＭｎＯ２一步氧化，即可获得较好收率的产物（１ａ～１ｃ）．所有Ｓｃｈｉｆ碱大环配合物和氮杂大环自由配体均经元素分析、ＩＲ、１ＨＮＭＲ和ＭＳ等证实了它们的结构和组成．Schiff base macrocyclic complexes (4a 4c) with good yield were synthesized by using Ba 2+ as template ion by reaction of 15 di( o aminophenoxy) 3 oxapentane (3) with 4 substituted 26 dicarbonylphenol (1a 1c) respectively. The complexes (4a 4c) were reduced with NaBH 4 to afford azamacrocyclic free ligands (L 1 L 3). The synthetic method of the intermediates (1a 1c) was studied and improved, 4 substituted 26 di (hydroxymethyl) phenol was oxidated with activated MnO 2 obtaining (1a 1c) in good yield. All these macrocyclic Schiff base complexes and aramacrocyclic free ligands were identified by elemental analysis and spectral analysis (IR, 1HNMR,MS).
