几种Salen双肟类衍生物及其配合物的合成与表征

摘要

以1,2.二胺氧乙烷、1,3.二胺氧丙烷、1,4-二胺氧丁烷及3种水杨醛衍生物为原料,以无水乙醇为溶剂,在常压、55℃条件下合成了 9种新型的Salen双肟类衍生物,与过渡金属盐类作用制备了其配合物.用元素分析、红外光谱、核磁共振及差热-热重等测试技术对化合物的结构进行了表征.结果表明,所合成的新型Salen双肟类衍生物均为四齿含氮配体并与过渡金属离子有较强的配位能力,反应条件温和,收率较高.%Nine kinds of novel salen-type bisoxime derivatives were synthesized at atmosphere,55 ℃ from self-made 1,2-bis (aminooxy) ethane, 1,3-bis (aminooxy) propane, 1,4-bis (aminooxy) butane and three kinds of salicylaldehyde derivatives in anhydrous ethanol solvent.Their complexes were prepared from the salen-type bisoxime derivatives and transition metal salts.The compounds were characterized by elemental analysis, IR,1H NMR and TG-DTA.The results indicated that the novel salen-type bisoxime derivatives were all good tetradentate N2O2-donating ligands and had good capability of coordination with transition metal ions.The reaction conditions were mild and the yield of products was high.
