SYNTHESIS AND CHARACTERIZATION OF CATIONIC BIS-AZIRIDINE COBALT(III) COMPLEXES CONTAINING SCHIFF BASE LIGANDS

摘要

The syntheses of cationic bis-aziridine (Az) complexes, [Co(SB)(Az)(2)]Cl, where SB is a Schiff base ligand (SB = acacen, salen, salpn, hapen, happn or saloph) by oxidation of cobalt(II) in basic solution containing the ligands are described. A corresponding series of methylamine complexes [Co(SB)(CH3NH2)(2)]Cl was also prepared (SB = acacen, salen, salpn, hapen or saloph). Both series of complexes were characterized by H-1 NMR spectroscopy, while the aziridine complexes and selected methylamine complexes were also investigated by C-13 NMR spectroscopy. [References: 17]
