New bis(diphenylphosphino)methane, (dpm) complexes of palladium have been prepared from PdCl2dpm, either by borohydride reduction of halide abstraction in the presence of added ligand.The catalytic activities of these and other polynuclear palladium and copper complexes in the CO2/H2 reaction have been tested.The results confirm the catalytic formation of alkyl formate and dialkyl formamide, but the juxtaposition of two or more metal centres does not appear to promote the catalytic formation of C2-compounds (oxalate).
