New hydrophobic β-diphosphoramides of the type <(Me2N)2P(O)>2NR where R = hexyl(OHIPA), dodecyl(ODIPA) or benzyl(OBIPA) have been synthesized; their hydrophobic character and their complexing and extracting abilities have been measured and compared to those of NIPA (R = methyl).It is shown that, amoung the four ligands, the compound ODIPA presents the best extracting properties because of its insolubility in water and its important complexing ability.
