1,2-Bis-N-[2′-(diphenylphosphanyl)benzoyl] diaminobenzene (dppbH; 1) was prepared by peptidic coupling and shown to exist, in the solid state, in the form of hydrogen-bonded dimers by single-crystal X-ray structure analysis. As expected, 1 reacts with [MCl2(cod)] (M = Pd, Pt; cod = cyclooctadiene) to form square-planar complexes. However, in the case of palladium [PdCl2(dppbH)] (2) is obtained, while in the case of platinum [Pt(dppb)] (3) is formed. Thus, the nature of the metal induces a completely different coordination mode: In 2, the dppbH ligand only coordinates through the two phosphorus atoms, while in 3 a dppb ligand, formed by deprotonation of the two amino functions in dppbH, coordinates through the two phosphorus atoms and through the two nitrogen atoms. The single-crystal X-ray analyses of the two square-planar complexes reveal 2 to contain the two phosphorus atoms in a trans coordination mode and 3 to contain the two phosphorus atoms in a cis coordination mode.

Reaction of 1,2-bis-N-[20-(diphenyl-phosphanyl)benzoyl]diaminobenzene (H2N2P2: H21) with Ni(ClO4)2 produced the corresponding tetradentate diamidato-bis(phosphine) nickel(II) complex Ni(N2P2) (2). Reactivity studies of 2 with reductants yielded the orthometallated product [M+][Ni(N2PC)] ([M+][3]), where M = Cp/ 2CoIII or NBu4 and N2PC = N-((2-diphenylphosphino)-benzoyl)-N0-((1-phen-2-idyl)oxomethyl)- 1,2-diaminobenzene, via reductive cleavage of one of the PPh2 groups of H21. The synthesis and characterization of the complexes are described.
