Tris{2-[N-(quinolin-8-yl)carbamoylmethoxy]phenyl}phosphine oxide: synthesis and coordination properties
摘要
A new phosphine oxide derivative, tris{2-[N-(quinolin-8-yl)carbamoylmethoxy]-phenyl}phosphine oxide, was synthesized by the alkylation of tris(2-hydroxyphenyl)-phosphine oxide. The synthesized compound exhibits the properties of a tripodal polytopic O,N ligand with respect to lanthanum and terbium cations. The composition and structures of the ligand and its complexes were determined by elemental analysis, vibrational and multinuclear NMR spectroscopy (1H, 13C, 31P), and X-ray diffraction.
