The Synthesis and Characterization of Substituted Aminomethylglyoximes and Aminophenylglyoximes and Their Complexes with Some Transition Metals

Abstract

In this study, six new unsymmetrical vic-dioximes, N-(3,4-dimethylphenyl)aminomethylglyoxime ((LH2)-H-1), N-(3-chloro-4-methylphenyl)aminomethyl-glyoxime ((LH2)-H-2), N-(2,6-dimethylphenyl)aminomethyl glyoxime ((LH2)-H-3), N-(3,4-dimethylphenyl)aminophenylglyoxime ((LH2)-H-4), N-(3-chloro-4-methylphenyl)-aminophenylglyoxime ((LH2)-H-5) and N-(2,6-dimethylphenyl)aminophenylglyoxime ((LH2)-H-6) have been synthesized from chloromethylglyoxime or chlorophenylglyoxime and the corresponding substituted aromatic amines. The Co(II), Ni(II) and Cu(II) complexes of these ligands were prepared. The structures of these new ligands and their complexes are proposed based upon IR, UV-Vis, H-1 NMR spectral data, magnetic measurements, and elemental analyses.
