WebDesired separation processes require extraction of An(III) over Ln(III) in nonpolar solvent systems without degradation over a viable time-scale.2Traditional separation techniques present challenges since these elements have similar atomic radii and other physical properties. Figure 1. Common soft-N-donor 1,2,4-triazine scaffolds A Josiphos ligand is a type of chiral diphosphine which has been modified to be substrate-specific; they are widely used for enantioselective synthesis. They are named after the technician who made the first one, Josi Puleo.
