Transition metal (Group 6, Ru and Group 10) derivatives of aminophosphines, Ph2PN(H)R (R=Ph, C6H11)

The reactions of aminophosphines with Group 6 metal carbonyls afford both mono-substituted and disubstituted complexes. The reaction of Ph2PN(H)C6H11 with molybdenum tetracarbonyl derivative gives a mixture of cis and trans-isomers. The reaction of Ph2PN(H)Ph with Pd(COD)Cl2 leads to the PN bond cleavage to give chloro bridged dimer, [Pd(PPh2O)(PPh2OH)(μ-Cl)]2, whereas with Pt(COD)Cl2, disubstituted cis-[PtCl2{PPh2N(H)R}2]2 was obtained. The reaction of Ph2PN(H)C6H11 with RuCl2(DMSO)4 or RuCl2(PPh3)3 leads to the formation of ionic complex, [RuCl{Ph2PN(H)C6H11}3]Cl.
