The purpose of this work was to develop further the separation of the platinum group metals by countercurrent extraction first reported by BERG AND SENN'~~. 'The earlier work dealing with the extractive separation of the chloro-compleses of platinum and palladium, platinum and rhodium, and rhodium a
Three new bifunctional phosphinoamide ligands of the type Ph2PCH2C(O)NHR (R = H, HDPA; Me, MDPA; Ph, PDPA) were prepared and characterized. Their ruthenium(II) complexes prepared from two different precursors, RuC12-(DMSO)4 and RuClz(PPh3) 3, are of similar composition and correspond to the formula,
Rhodium(I), iridium(I), palladium(lI) and platinum(II) complexes of the phosphinoamide ligands, Ph2PCH2CONHR (R = H, HDPA; Me, MDPA; Ph, PDPA) were prepared and characterized by using conductivity data, i.r., 1H and31P(H) n.m.r, spectral data. Reaction of the ligands with MCI(PPh3) 3 and MCI(CO)(PPh
