Synthesis, Characterization, and Structures of Palladium(II) and Platinum(II) Complexes Containing N,N-Bis(diphenylphos-phanyl)Naphthylamine

The reaction of 1-naphthylamine with two equivalents of chlorodiphenylphosphine in the presence of triethylamine gave the ligand C10H7-1-N(PPh2)2 (1). Reaction of 1 with PdCl2(CH3CN)2 or PtCl2(cod) (1:1 molar ratio) afforded the complexes cis-[PdCl2{C10H7-1-N(PPh2)2}] (2) and cis-[PtCl2{C10H7-1-N(PPh2)2}] (3), respectively. Compounds 13 were identified and characterized by multinuclear NMR (1H, 13C, 31P NMR) and IR spectroscopy. Crystal structure determinations of complexes 2 and 3 were carried out.
