Abstract

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 R1 and R2, either identical or different, represent H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl, benzyl, diphenyl or tolyl group; R3 represents H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl, tolyl or linear or branched C1-C12 alkoxy group; while R4 represents H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl or tolyl group.Field of applications: the processing of used nuclear fuels via a hydrometallurgical route.
