两种新的N、O多齿配体的合成

SYNTHESIS OF TWO NOVEL MULTIPLY DENTATE LIGANDS CONTAINING N、O DONOR ATOMS

本文报导两种新的含N、O配位原子，酚氧和酰胺结构单元的四齿配体、N，N’─双（2─羟基苯基）丙二酰胺（H4hpma）和N，N─双（2─羟基苯基）草酸二酰胺（H4hpox）的合成方法。H4hpmaH4hpox在一定条件下对中心离子配位可以去1～4个质子形成稳定的配合物。元素分析和红外光谱确认了其组成结构。

?In this papel the synthetic methods of two novel tetradentate ligands,which contain N、O donor atoms and the Structural elements of phenol and amide,are reported. They are N,N’-bis (2-hydroxy phenyl ) malondiamide (abbrivated as H4hpma)and N,N’-bis (2-hydroxyphenyl ) oxamide (abbreviated as H4hpox). The ligands synthesized coordinated to the center ions in certain condition with 1 ~4 of deprotnation to form sfable complexes. Their composltion and structure were determined by element analysis and IR spectra
