The reaction of 2 with diethyl(diphenylphosphinomethyl)amine (ddpa) (1:4) yields RhCl(CO)(ddpa)2, a mononuclear complex able to act as ligand towards a second metal through its uncoordinated nitrogen atom.Two examples are described, namely the reaction with 2 leading to Rh2(μ-Cl)Cl(μ-CO)(CO)(μ-ddpa)2 and that with PdCl2(COD) (COD = 1,5-cyclooctadiene) to PdRh(μ-Cl)Cl2(CO)(μ-dppa)2.In both homo- and hetero-dinuclear complexes, the ligand is thought to retain a head-to-head arrangement.
