Synthesis of Novel Macrocyclic Lactam Based Receptors for Alkali or Transition Metal Cations and Cr2O7 2– Anions

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.
