New tripodal ligand on the triphenylphosphine oxide platform with 1,2,3-triazole side arms: synthesis, structure, coordination, and extraction properties

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 ( 1 H, 13 C, 31 P) 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
