Abstract
In this study, a novel iminooxime ligand having dimetoxide groups as well as its complexes with copper(II), nickel(II), zinc(II), cadmium(II), and cobalt(II) were synthesized. We have used 3,4-dimetoxyacetophenone as starting material, and synthesized isonitroso-3,4-dimetoxyacetophenone by reaction of 3,4-dimetoxyacetophenone with n-butyl nitrite in presence of sodium ethoxide. 3-hydroxyphenylimino-isonitroso-3,4-dimetoxyacetophenone(3) was obtained from reaction of such nitroso compound with 3-aminophenol and its complexes were prepared by treatment of iminooxime with metal salts as Cu(II), Ni(II), Zn(II), Cd(II), and Co(II) in methanol, respectively. All of the structures were characterized by using spectroscopic techniques.
