Synthesis of N′‐(4′‐Benzo[15‐crown‐5]‐phenylaminoglyoxime and Its Complexes with Copper(II), Nickel(II), and Cobalt(II)
摘要:
N'-(4'-Benzo[15-crown-5]phenylaminoglyoxime (H2L) and the sodium chloride adduct of N'-(4'-benzo[15-crown-5]phenylaminoglyoxime ((H2LNaCl)-Na-.) have been prepared from chlorophenylglyoxime, 4'-aminobenzo[15-crown-5] and sodium bicarbonate or sodium bicarbonate and sodium chloride. Nickel(II), cobalt(II) and copper(II) complexes of H2L and H2L-NaCl have a metal-ligand ratio of 1:2 and the ligand coordinates through the two N atoms, as do most of the vic-dioximes. Their IR spectra and elemental analyses are given, together with H-1 NMR spectra of the ligands.
