Synthesis of Eight New Substituted Phenylamino and Diaminoglyoximes and their Complexes with Some Transition Metals

Abstract

Eight new substituted phenylamino and diaminoglyoximes; N-(3-methylphenyl)aminoglyoxime (MPAGH₂), N-(2,6-dimethylphenyl)amino-glyoxime (DMPAGH₂), N-(2-chloro-4-methylphenyl)aminoglyoxime (CMPAGH₂), N-(2,4-dichlorophenyl)aminoglyoxime (DCPAGH₂), N,N′-bis-(3-methylphenyl)diaminoglyoxime (BMPAGH₂), N,N′-bis(2,6-dimethyl-phenyl)diaminoglyoxime (BDMPAGH₂), N,N′-bis-(2-chloro-4-methyl-phenyl)diaminoglyoxime (BCMPAGH₂), and N,N′-bis(2,4-dichlorophenyl)-diaminoglyoxime (BDCPAGH₂) have been synthesized by the reactions of anti-chloroglyoxime and dichloroglyoxime with substituted aromatic amines in absolute ethanol. All these dioximes are in the anti-form according to IR and ¹H NMR spectral data. The Ni(II), Cu(II) and Co(II) complexes of eight vic-dioximes have been prepared and their structures have been determined by using IR and UV-VIS spectral data and elemental analyses.
