利用乙二胺及其衍生物的Mannich反应在无催化剂的条件下合成了9种Salen型新的配体, 化合物1和2在无溶剂条件下合成, 化合物3a～3g在Salen配体中引入呋喃杂环, 对其与金属的配位提供了多种可能性. 所得化合物结构经元素分析, IR, MS, 1H NMR等确认, 同时用X射线单晶衍射测定了化合物1和3b的晶体结构.

关键词: Mannich碱, 合成, X射线晶体衍射

Nine kinds of new salen ligands were synthesized by Mannich condensation without catalyst. Compounds 1 and 2 were synthesized under solvent-free condensations. Compounds 3a～3g are the new salen ligands with furan rings, which could provide coordination modes to metal ions. The chemical structures of the title compounds were characterized by elementary analysis, IR, 1H NMR and MS techniques. Compounds 1 and 3b were identified by single crystal X-ray diffraction analysis.

Key words: Mannich base, synthesis, X-ray diffraction analysis
