Salen型双肟配体及其铜(Ⅱ)配合物的合成与表征

Syntheses and Characterization of A Salen-type Bisoxime Ligand and its Copper(Ⅱ) Complexes

以1,2-二胺氧乙烷和2'-羟基苯乙酮为原料,合成了Salen型双肟配体2,2′-[1,1′-(乙二氧二氮)二乙基]二酚(H2L)。在甲醇-丙酮或乙醇-丙酮的混合溶剂中,H2L与乙酸铜反应,生成了两种不同结构的配合物,通过元素分析、1HNMR、FT-IR和UV-Vis等表征方法确定了配合物的可能结构为[CuL].CH3OH(1)和[{(CuL)2(OAc)2}Cu](2)。

A Salen-type bisoxime ligand 2,2＇-[1,1＇-（ethylenedioxydinitrilo）diethylidyne]diphenol（H2L） had been synthesized by the reaction of 1,2-bis（aminooxy）ethane with 2 equivalents of 2′-hydroxyacetophenone.H2L reacts with Cu（CH3COO）2·H2O and generats two complexes in methanol-acetone or ethanol-acetone mixed solvents,respectively.The probable structures are ·CH3OH and [{（CuL）2（OAc）2}Cu] for complexes 1 and 2,which were determined by EA,1H-NMR,FT-IR and UV-Vis spectra,et al.
