摘要
配体 A 是通过 4-氨基安替比林与肼反应合成的,配体 B 是通过 4-氨基安替比林与乙二胺反应合成的,配体 C 是通过 4-氨基安替比林与苯甲醛和肼反应合成的。经元素分析、傅立叶变换红外光谱和核磁共振(1H 和 13C NMR)光谱证实,成功合成了所需的希夫碱衍生物。实验结果与之前公布的数据非常吻合。为了评估合成的希夫碱在形成稳定的金属配合物方面的反应性,研究人员考察了它们与铜(II)离子的反应。结果表明,配体 A 和配体 B 有效地利用了 4-氨基安替比林-N 和偶氮甲基-N 基团的四个氮原子(NNNN)与铜(II)离子配位,而配体 C 则利用其四个偶氮甲基氮原子与铜(II)离子配位。此外,将制得的铜(II)配合物在 600 °C 的空气中热处理 3 小时,成功生成了氧化铜(II)。扫描电子显微镜-能量色散 X 射线分析数据表明,制得的氧化铜(II)纯度高,形态均匀且结构良好。关键字:希夫碱、4-氨基安替比林、铜(II)离子、热分解、扫描电子显微镜/能谱 X 射线、形态 Bull.Chem.Soc.2024, 38(2), 431-443.

Capturing of the copper(II) ions by several 4-aminoantipyrine Schiff bases: Synthesis, spectroscopic analysis, and decompsition of the resulted complexes into copper(II) oxide
Here we describe the synthesis and characterization of three Schiff bases based on 4-aminoantipyrine, ligand A, ligand B, and ligand C. Ligand A was synthesized by reacting 4-aminoantipyrine with hydrazine, ligand B by reacting 4-aminoantipyrine with ethylenediamine, and ligand C by reacting 4-aminoantipyrine with benzaldehyde and hydrazine. The synthesis of the desired Schiff base derivatives was successfully achieved, as confirmed by elemental analysis, Fourier-transform infrared (FT-IR) spectroscopy, and nuclear magnetic resonance (1H and 13C NMR) spectroscopy. The obtained experimental results exhibited excellent agreement with previously published data. To evaluate the reactivity of the synthesized Schiff bases in forming stable metal complexes, their reaction with copper(II) ions was examined. The results indicated that ligand A and ligand B effectively utilized the four nitrogen atoms (NNNN) from the 4-aminoantipyrine-N and azomethine-N groups to coordinate with copper(II) ions, while ligand C coordinated with the copper(II) ions using its four azomethine nitrogen atoms. Furthermore, the manufactured copper(II) complexes were subjected to thermal treatment in the air at 600 °C for 3 h, resulting in the successful generation of copper(II) oxide. Scanning electron microscopy-energy-dispersive X-ray analysis data demonstrated that the produced copper(II) oxide exhibited high purity and possessed a uniform and well-structured morphology.
