Diphenyl-2-pyridylphosphine is an organophosphorus compound with the formula P(C6H5)2(2-C5H4N). It is the most widely used mono-pyridylphosphine ligand. Other mono-pyridylphosphines ligands (3- 4-) are not common in chemical literature however tris-pyridylphosphines have been thoroughly investigated as ligands in transition metal complexes used for catalysis. Pyridylphosphines including diphenyl-2-pyridylphosphine may bind transition metals as monodentate or bidentate ligands4. Diphenyl-2-pyridylphosphine behaves as a P-bound monodentate ligand or a PN-bound bidentate ligand. Diphenyl-2-pyridylphosphine is a sought after ligand for its ability to relay protons to transition metals such as palladium(II) in homogeneous catalysis.
