Chiral Dinuclear Eu^III, Tb^III, and Y^III Complexes Supported by P‐Stereogenic Linear Tetraphosphine Tetraoxide

Abstract

A P-stereogenic linear tetraphosphine tetraoxide, (R,R)-or (S,S)-dpmppm(=O) 4 , was synthesized to prepare C 2 dinuclear M(hfa) 3 complexes (M = Eu, Tb, Y) as the first example of lanthanide(III) complexes with P-chiral multidentate phosphine oxides. The mononuclear M(hfa) 3 complexes (M = Eu, Y) with a P-chiral diphosphine dioxide,
