Synthesis and Complex-Formation of 6 New Unsymmetrical Vic-Dioximes

anti-Chlorophenylglyoxime (CPGH2) has been synthesized by chlorination of anti-phenylglyoxime. The reaction of CPGH? with suitable aryl- or arylalkylamines in ethanol at -10°C gives the unsymmetrical vic-dioximes, namely, anilinophenylglyoxime (APGH?). p-toluidinophenylglyoxime (PTPGH?), o-toluidinophenylglyoxime (OTPGH), benzilaminophenylglyoxime (BAPGHz). p-anisidinophenyl- glyoxime (PAPGH). 1-naphthylaminophenylglyoxime (NAPGH). The Cu(II) and Ni(II) complexes of these ligands are square-planar while the Co(II) complexes are octahedral with water molecules as axial ligands. H-NMR, IR and UV-VIS data are given.
