Abstract
New tetraphosphoryl tripodal ligands on the triphenylphosphine oxide platform [2-Ph2P(O)(CH2) n OC6H4]3PO with different linker length ( n = 3, 4) were synthesized. Composition and structure were found by elemental analysis, IR, multinuclear (1H, 13C, 31P) NMR spectroscopy, and X-ray diffraction. Extraction properties of the ligands were studied by the example of recovery of micro amounts of f -block elements from aqueous phase to 1,2-dichloroethane.
