Synthesis and Extraction Properties of Tripodal Tetraphosphoryl Ligands on the Triphenylphosphine Oxide Platform
Russian Journal of General Chemistry(2023)
Abstract
New tetraphosphoryl tripodal ligands on the triphenylphosphine oxide platform [2-Ph2P(O)(CH2)nOC6H4]3PO with different linker length (n = 3, 4) were synthesized. Their composition and structure were determined by elemental analysis, IR and multinuclear (1H, 13C, and 31P) NMR spectroscopy, and X-ray diffraction analysis. Extraction properties of the ligands were studied using the example of extraction of microamounts of f-elements from an aqueous phase into 1,2-dichloroethane.
