The synthesis of substituted 4,4'-thiobis (aminophenylglyoxime) and their polymeric metal complexes with Cu(II), Ni(II) and Co(II) salts

Abstract

4,4'-Bis(chloroacetyl)diphenyl thioether (HL) was synthesized from chloroacetyl chloride and diphenyl thioether in the presence of AlCl3 as catalyst in a Friedel-Crafts reaction. Subsequently, its keto oxime $(H_2L)$ and glyoxime $(H_4L)$ derivatives were also prepared. Then 3 new substituted 4,4'-thiobis(aminophen-ylglyoxime) $(H_4L^{1-}3)$ were synthesized from 4,4'-thiobis(chlorophenylglyoxime) and the corresponding amines. The Ni(II), Cu(II) and Co(II) complexes of these ligands were prepared. The structures of these ligands and their complexes were identifed by FT-IR, $^1H$ NMR and ICP-AES spectral data, elemental analyses and magnetic measurements.
