- Аннотация: N-Diphenylphosphoryl-N'-[ω-(alkoxy/tetrahydrofuryl)alkyl]ureas have been synthesized basedon a highly efficient one-pot catalytic process and their extraction properties have been studied with respectto f-elements in nitric acid media. The influence on the extraction characteristics of the presence of an alkoxyor tetrahydrofuryl group located in the ω-position of the normal N'-alkyl radical of phosphorylurea has beenrevealed. It has been shown that N-(diphenylphosphoryl)urea containing N'-[2-(tetrahydrofur-2-yl)ethyl]radical has the best extraction properties with respect to the studied f-elements, especially this effect is pronouncedfor uranium(VI). This dependence has been theoretically substantiated when simulating complexformation by the density functional theory method (DFT, PBE, cc-pVDZ), since the coordination of thef-element ion to the oxygen atom of the furyl radical attached to the ethylene carbon chain turns out to bepreferable.
