Enantiomerization of chiral uranyl-salophen complexes via unprecedented ligand hemilability: toward configurationally stable derivatives

The synthesis of a new chiralmacrocyclic uranyl-salophen derivative and the analysis of its configuration stability carried out by dynamic chiral HPLC are described. The studies have shown that the new structural motif has imparted a higher configurational stability, thus raising the half-life for the enantiomerization to more than 2 months at room temperature.
