Synthesis and complex formation of substituted amino-P-chlorophenylglyoximes of unsymmetrical vic-dioximes

Abstract

In this study, anti-p-chlorophenvichloroglvoxime (CgH6Cl2N202) has been synthesized by chlorination of anti-p-chlorophenvlglvoxime. The reaction of C8H6Cl2N202 with p-chloroaniline, o-toluidine, 1-naphthylamine and benzidine in ethanol between -10°C and -15°C gives unsymmetrical vic-dioximes, namely, p-chloroanilino-p-chlorophenyIglyoxime(C i4H11CI2N3O2), o-toluidino-p-chiorophenyl-ghoxime (C15H14ClN302), I-naphtylamino-p-chlorophenylglioxime (C18H14C1N302), 1,1 -biphenyM-amino-T-amino-p-chlorophenylglioxime C20H17C1N402). The Ni(ll) and Cu(ll) complexes of these ligands are square-planer while the Co(ll) complexes are octahedral with water molecules as axial ligands. 1H-NMR, AAS, 1R spectra and elemental analyses data are given. © 1995, Taylor & Francis Group, LLC.
