新型 Salen 双肟化合物及其钴配合物的合成与表征

摘要

以3，5-二溴-2-羟基苯甲醛及1，4-二胺氧丁烷、1，3-二胺氧丙烷、1，2-二胺氧乙烷为原料，在无水乙醇溶剂中合成了3种新型的 Salen 双肟化合物。以 Salen 双肟化合物及乙酸钴为原料，合成了一种过渡金属 Co 配合物。采用 IR、元素分析、1 H NMR 及 TG-DTA 等手段对化合物作了表征。结果表明，所合成的新型 Salen 双肟化合物与钴（Ⅱ）离子有较强的配位能力。%Three kinds of novel Salen-type bisoxime compounds were synthesized from 3,5-dibromo-2-hydroxybenzaldehyde and home-made 1,4-bis( aminooxy)butane,1,3-bis( aminooxy)propane,1,2-bis (aminooxy)ethane in anhydrous ethanol solvent. A kind of transition metal cobalt(Ⅱ)complex was also prepared from the Salen-type bisoxime compound and cobalt(Ⅱ)acetate. The ligands and complexes were characterized by IR,elemental analysis,1 H NMR and TG-DTA. The results indicated that the novel Salen-type bisoxime compounds had good capability of coordination with cobalt(Ⅱ)ions.
