N2 - Oxidation of 2-(N-(diphenylphosphino)amino)-4-methylpyridine (1) with elemental sulfur or gray selenium afforded the corresponding sulfide and selenide (4-CH3)C6H3N-2-NH(P(E)Ph2) [E=S(2), Se(3)], respectively. The reaction of 1 with group-10B metal chlorides afforded cis-MCl2[1-κ2P,Npy][M=Pd(4), Pt(5)], and the side product trans-PdCl2[(4-CH3)C6H3N-2-NH(P(O)Ph2)-κNpy]2 (6), respectively. Compounds 1–5 have been isolated and characterized by multinuclear NMR spectroscopy (1H, 13C, 31P NMR), infrared, and elemental analysis. Crystal-structure determinations were performed on 2, 5, and 6. The role of 4 as a pre-catalyst in the Suzuki cross-coupling reaction was additionally studied.
