Ruthenium complexes of tris(2-pyridyl)phosphine can be used as hydroformylation and hydrogenation catalysts; however, these complexes, specifically, RuHCl(P(Py)3)3 and RuCl2(P(Py)3)3, are generally prepared indirectly by the substitution of PPh3 for P(Py)3. Given the structural similarity between PPh3 and P(Py)3, it is logical to consider if RuHCl(P(Py)3)3 and RuCl2(P(Py)3)3 can be synthesized directly. The direct synthesis of these complexes, as well as Ru complexes of the oxidized ligands: O=P(Py)3 and Se=P(Py)3, will be presented along with spectroscopic (31P NMR, infrared, and UV-Visible), and structural details (X-ray crystal structures).
