Synthesis of Novel Lactam Ionophores Containing Crown Ether Moieties and Investigation of Their Extraction Abilities Towards Heavy Metal Cations. Journal of Inclusion Phenomena and Macrocyclic Chemistry, 68, 85-91. DOI: 10.1007/s10847-010-9736-11388-31271573-1111https://dx.doi.org/10.1007/s10847-010-9736-1https://hdl.handle.net/20.500.12395/25307The article describes the syntheses and extraction properties of new lactam ionophores. These lactam derivatives were easily synthesized via aminolysis of dimethyl 2,2'-(6,6'-methylenebis(2-tert-butyl-4-methyl-6,1-phenylene)bis(oxy))diacetate or dimethyl 2,2'-(2,2'-methylenebis(4-chloro-2,1-phenylene))bis(oxy)diacetate with corresponding diamine compounds at one step. The extraction studies of lactam ionophores were performed toward dichromate anion and alkaline and transition metals such as Li+, Na+, K+, Co2+, Hg2+ and Pb2+. All the structures of the ionophores were confirmed by spectroscopic techniques and elemental analysis.en10.1007/s10847-010-9736-1info:eu-repo/semantics/openAccessCrown EtherLactamHeavy MetalLiquid-Liquid ExtractionArticle688591Q3WOS:000281702800007Q2
