    Synthesis of N-(4 '-benzo[15-crown-5])biphenylaminoglyoxime and its complexes with some transition metals
    (MAIK NAUKA/INTERPERIODICA/SPRINGER, 2004) Karapinar, E; Karapinar, N; Ozcan, E
    N'-(4'-Benzo[15-crown-5])biphenylaminoglyoxime (H2L) and sodium chloride salt of N'-(4'-benzo[15-crown-5])biphenylaminoglyoxime (H2L . NaCl) have been prepared from 4-biphenylchloroglyoxime, 4'-aminobenzo[15-crown-5], and sodium bicarbonate and sodium chloride. Nickel(II), cobalt(II), and copper(II) complexes with 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.
