A new tripodal O-donor ligand, tris(2-N,N-dibutylcarbamoylmethoxyphenyl)phosphine oxide (L), was synthesized. This potentially tetradentate ligand L exhibits variable denticity upon complexation with UO2(NO3)2, Nd(NO3

A ligand system containing three carbamoyl moieties secured onto a triphenylphosphine oxide platform (2-R2NC(O)CH2OC6H4)3PO, where R = Me (1), Bu (2), and cyclo-Hex (3) has been developed for lanthanide complexation and extraction from aqueous solutions. The influence of non-coordinating alkyl substituents at the nitrogen atoms in the carbamoyl side arms on coordination and extraction properties of tripodal ligands 1–3 was studied. Two new ligands 1 and 3 with alkyl substituents of different bulkiness were synthesized and characterized by spectroscopic methods. Single-crystal X-ray structures have been determined for ligands 1 and 2. The selected coordination chemistry of ligands 1–3 with Ln(NO3)3 (Ln = La, Nd, Lu) has been evaluated. The 1:1 complexes of all ligands 1–3 were synthesized and characterized via elemental analysis and IR spectroscopy; in addition, the crystal structure of the ligand 1 complex with neodymium nitrate was determined by X-ray diffraction. Solution structure of 1:1 complexes was examined by IR and multinuclear (1H, 13C, and 31P) NMR spectroscopy. A formation of 1:2 complexes with lanthanum and lutetium nitrates (IR, NMR, ESI-MS) has been examined and structure of the major components of 1:2 complexes solutions has been suggested for ligands 1–3. Preliminary extraction studies of Ln(III) (Ln = La, Nd, Eu, Lu) from 3 M NH4NO3 into 1,2-dichloroethane show that ligands 2 and 3 recover lanthanides much better than their mono analog [2-(Bu2NC(O)CH2O)-5-Et-C6H3]P(O)Ph2 and known extractant Ph2P(O)CH2C(O)NBu2.

Abstract: New hybrid tripodal propeller ligands on the triphenylphosphine oxide platform with triazole rings in the side arms and alkyl and aryl substituents in the triazole fragments have been synthesized by the click reaction. Composition and structure of the prepared compounds have been established by vibrational (IR, Raman) and multinuclear (1H, 13C, 31P) NMR spectroscopy, elemental analysis, and mass spectrometry. Coordination and extraction properties of the prepared compounds toward Pd(II) have been studied by the example of one of the ligands. Graphic abstract: [Figure not available: see fulltext.]
