Synthesis of N′‐(4′‐Benzo[15‐crown‐5]‐phenylaminoglyoxime and Its Complexes with Copper(II), Nickel(II), and Cobalt(II)

Abstract

N′‐(4′‐Benzo[15‐crown‐5]phenylaminoglyoxime (H₂L) and the sodium chloride adduct of N′‐(4′‐benzo[15‐crown‐5]phenylaminoglyoxime (H₂L · NaCl) 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 ¹H NMR spectra of the ligands.

Keywords:

• Crown compounds
