A NOVEL BICYCLIC DIAMIDE WITH HIGH BINDING AFFINITY FOR TRIVALENT f-BLOCK ELEMENTS

Abstract

A new bicyclic diamide compound, 3,9-diaza-3,9-dioctylbicyclo[4.4.0]decane-2,10-dione (1) has been prepared, and its affinity for Eu3+ and Am3+ has been explored using liquid-liquid extraction methods. Molecular mechanics calculations have shown that the two amide oxygen atoms in 1 should be ideally situated for binding to trivalent actinide or lanthanide ions and should form strong complexes. The data in this report support this hypothesis. As determined by liquid-liquid extraction, the affinity of 1 for Eu3+ is on the order of 107 times greater than previously investigated malonamides. The extraction behavior for Am3+ is similar to that of Eu3+.
