SYNTHESIS AND CHARACTERIZATION OF CHIRAL Cu(II), Co(II), Ni(II) COMPLEXES OF N,N’-BIS(3-TERT-BUTYLSALICYLIDENE)-(R,R)-1,2-CYCLOHEXANEDIAMINE AND N,N’-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-(R,R)-1,2-CYCLOHEXANEDIAMINE

Abstract

      In this research we synthesis salicylaldehyde derivatives from the Reimer tiemann reaction of phenol derivatives and chloroform in ethanol and sodium hydroxide solution 30%. After this, we synthesized salen ligand from the condensation reaction of (R,R)-1,2-cyclohexanediamine and salicylaldehyde derivatives. And then, complexes were synthesized from ligands and transition metals including Cu(II), Co(II), Ni(II). Synthesized compounds were characterized by IR, UV-vis, ESI-LC/MS, 1H-NMR. The obtained result showed that the complexes were true. The central metals linked to N and O and H+ was separated from OH group.
