    Synthesis of Novel Macrocyclic Lactam Based Receptors for Alkali or Transition Metal Cations and Cr2O72- Anions
    (SLOVENSKO KEMIJSKO DRUSTVO, 2009) Ertul, Seref; Tombak, Haci Ahmet; Bayrakci, Mevluet; Merter, Orhan
    The article describes the syntheses and extraction properties of new lactam ionophores. These lactam derivatives were easily synthesized via aminolysis of 2,2'-methylenebis(4-chlorophenol) dimethylester or its corresponding acyl chloride with corresponding diamine compounds in THF or methanol-dichloromethane solvent systems in one step, respectively. The extraction studies of lactam ionophores were performed toward dichromate anion and alkaline and transition metal cations such as Li+, Na+, K+, Co2+, Hg2+ and Pb2+. All the structures of the ionophores were confirmed by spectroscopic techniques and elemental analysis.
