Crown compounds, halogenated benzo-and Dibenzocrown esters, metal cations. A method for the synthesis of new molecular receptor of molecular clips class based on diphenylglycoluryl containing fragment of benzo-18-crown-6 as a donor center has been developed. Found that the introduction of halogen atoms into molecules of benzo-12-crown-4 and benzo-18-crown-6 leads to a sharp increase in extraction activity and selectivity of the obtained halogen derivatives (GBKE) on gold or lead, when extracting them from a mixture of 30 metals. According to the extraction activity, GBKE usually exceed unsubstituted analogues and [3.3] dibenzo-18-crown-6. Product Description popup.authors А. Ляпунов В.И.Павловский Г.Л. Камалов Е. Кулыгина Е.
