| Abstract: | Summary 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, RuCl2-(DMSO)4 and RuCl2(PPh3)3, are of similar composition and correspond to the formula, RuCl(L)2(P-O)2]Cl (L = DMSO/PPh3; phosphinoamide). However, RuCl3-(AsPh3)2(MeOH) reacts with the phosphinoamide to yield a reduced product of the cis-RuCl2(P-O)2 type. The ligands and complexes were characterized by mass, i.r. and n.m.r. spectroscopy. Possible stereochemistries for the complexes are proposed. |
