2,9-dipyridyl-1,10-phenanthroline derivatives useful as actinide ligands, method for synthesizing same, and uses thereof

The invention relates to novel compounds which are useful as ligands of actinides, to the synthesis of these compounds and to their uses. These compounds fit the general formula (I) hereafter: wherein Rand R, either identical or different, represent H, a linear or branched, saturated or unsaturated C-Chydrocarbon group, a phenyl, benzyl, diphenyl or tolyl group; Rrepresents H, a linear or branched, saturated or unsaturated C-Chydrocarbon group, a phenyl, tolyl or linear or branched C-Calkoxy group; while Rrepresents H, a linear or branched, saturated or unsaturated C-Chydrocarbon group, a phenyl or tolyl group. Field of applications: the processing of used nuclear fuels via a hydrometallurgical route.
