A number of transition metals such as rhodium and ruthenium with the diphosphines xantphos and nixantphos have been found to be effective homogeneous catalysts for a variety of industrially important reactions. Zero-valent rhodium or ruthenium (or other transition metals) complexes containing these diphosphine ligands are to the best of our knowledge unknown. Here, we describe the synthesis, spectroscopic and structural characterization and reactivity of [xantphosM(CO)2] (M = Pd, Pt) and [nixantphosM(CO)2] (M = Pd, Pt), rare examples of spectroscopically characterized zerovalent dicarbonyl complexes.
