  Oxidative Dehydrogenation of Cu(II) Complexes with N-Aryl-N-2-hydroxybenzyl- and N-Aryl-N-2-hydroxynaphthylmethyleneamine Derivatives

  摘要：

  The reactions of Cu2+ Cu2+, and Ni2+ ions with N-phenyl-N-2-hydroxybenzyl- and N-phenyl-N-2-hydroxynaphthylmethyleneamine derivatives (HLn, n = 1-8) produced from the derivatives of aniline and aromatic o-hydroxyaldehydes are studied. Among the ions studied, only Cu2+ forms stable complexes Cu(L-n)2 . 2H(2)O. The structures of the synthesized compounds are studied by IR, UV, and EPR spectroscopies and differential thermal analysis. The magnetic moments of the Cu(L-n)(2) . 2H(2)O complexes are very small and range within 0.43-1.19 mu(B), depending on the ligand structure, which indicates a strong antiferromagnetic interaction between the Cu2+ ions. The temperature dependence of the magnetic susceptibility measured for the Cu(L-3)(2) . 2H(2)O complex (where HL3 is N-4-methoxyphenyl-N-2-hydroxybenzylamine) is closest to the theoretical curve calculated for the binuclear Cu(II) complexes connected by the intermolecular exchange interaction. The Cu(II) complexes with HLn are shown to undergo oxidative dehydrogenation to form the corresponding metal salicylaldiminates. This reaction can occur on heating in the absence of oxygen and is accompanied by the Cu2+ --> Cu+ transition.

  The synthesis, characterization and antimicrobial activity of Cu(II) complexes of some p-substituted aniline Schiff base ligands have been carried out. The Schiff bases were obtained from salicylaldehyde and o-vanillin. The Cu(II) complexes have been characterized by elemental analysis, conductivity measurement, infrared and electronic spectral data. The complexes were obtained either as metal chelates [Cu(L)2] or Schiff base adducts (CuCl2.2LH).xH2O. The metal chelates were non-electrolytes while the Schiff base adducts exhibited 1:1 or 2:1 electrolytes in methanol. The Cu(II) complexes exhibited slight antimicrobial activity against Escherichia coli ATCC® 8739™*, Staphylococcus aureus subsp. aureus ATCC® 6538™*, Bacillus subtilis subsp. spizizenii ATCC® 6633™* and Candida albicans ATCC® 2091™*. The complexes exhibited significant antifungal activity.                     KEY WORDS: Metal Chelates, Schiff bases, Adducts, Cu(II) complexes, Salicylaldimines   Bull. Chem. Soc.

  Abstract The relationship between molecular conformation and substituent effects of salicylaldehyde Schiff-base Cu(II) complexes was explored. For this study, eight samples of the complexes Cu(Sal-X)2 (X = OMe, Me, H, F, Cl, Br, CF3 and CN) were obtained by reaction of Cu(OAc)2 with Schiff base ligands (Sal-X) derived from Salicydaldehyde, and their crystal structures were characterized by the X-ray

  摘要 探讨了水杨醛席夫碱Cu(II)配合物的分子构象与取代基效应的关系。在本研究中，通过 Cu(OAc)2 与席夫碱配体的反应获得了 8 个配合物 Cu(Sal-X)2（X = OMe、Me、H、F、Cl、Br、CF3 和 CN）的样品（ Sal-X) 衍生自水杨醛，其晶体结构通过 X 射线衍射技术表征。QSPR 方法用于更深入地了解 Cu(Sal-X)2 的几何结构。结果表明，Cu(Sal-X)2的主要几何参数由苯胺环上的取代基决定。即Cu-O-N面与O-CN面之间的二面角τ1随着取代基给电子效应和吸电子效应的增加而增加，而取代基的电子效应对 τ2 有相反的影响，τ2 是苯胺环平面和 C-N-Cu 平面之间的二面角。此外，键长 L Cu - N 随着取代基激发态参数 σ cc ex 的增加而减小，这增强了 C-N 键的能量。
