Abstract

Rh(I), Ir(I), Pd(II) and Pt(II) metal complexes of bis(2-diphenylphosphino)ethyl)benzylamine(DPBA) and bis(2-diphenylarsino)ethyl)benzylamine (DABA) have been synthesized using various starting materials. Reaction of RhCl(CO)(AsPh3)2 with DPBA or DABA in methanol resulted in the formation of cationic complexes of the composition, [Rh(CO)(L)]Cl (L=DPBA or DABA). Interaction of [IrCl(COD)]2 with DPBA in benzene resulted in the formation of a neutral complex [IrCl(DPBA)]. Reaction of [PdCl2(COD)] with the ligand DPBA in benzene resulted in a cationic complex of the composition [PdCl(DPBA)]Cl. Interaction of [PdCl(DPBA)]BPh4 with SnCl2 gave the complex [Pd(SnCl3)(DPBA)]BPh4. The ligands DPBA and DABA react with PtCl2(COD) in acetone to give neutral, Pt(II) complexes of the type, [PtCl2L] (L=DPBA or DABA). All the complexes were fully characterized by elemental analysis, conductivity measurements, IR and far-IR and 31P{1H} NMR spectral data.
