Аннотация: A series of (2-carbamoylethyl)diphenylphosphine oxides (CEPO) has been synthesized from commerciallyavailable reagents: chlorodiphenylphosphine and acrylamides. Effect of coordinating fragmentsPh2P(O)(CH2)2C(O), nature of oligoyl group that binds these fragments, and the presence of additionalcoordinating centers in CEPO on extraction properties toward actinides and lanthanides has been studied. Ithas been found that N,N′-methylene-bis[3-(diphenylphosphoryl)propionamide] (III) containing two diphenylphosphorylpropionylfragments bound by rigid HNCH2NH linker shows the highest efficiency in extraction ofactinides (recovery extent is ∼73% for U(VI) and ~85% for Th(IV)), whereas ligand V containing the maximumnumber of such phosphorylcarbonyl groups in conformationally non-rigid nitrogen heterocyclic matrixand CEPO (II) containing additional C=O group in the alkyl fragment at the nitrogen atom of carbamoylfragment exhibit considerable preference in the extraction of lanthanides (extraction of gadolinium with thiscompound is close to 92%). Obtained data display that highly efficient and selective extractants for both 4fand 5f elements can be constructed on the basis of (2-carbamoylethyl)diphenylphosphine oxides
