  Synthesis and Catalytic Activity of Molybdenum–Dinitrogen Complexes Bearing Unsymmetric PNP-Type Pincer Ligands

  摘要：

  Novel dinitrogen-bridged dimolybdenum complexes bearing unsymmetric PNP-type pincer ligands are prepared and characterized by X-ray analysis. A molybdenum-dinitrogen complex bearing 2-(di-1-adamantylphosphino)methyl-6-(di-tert-butylphosphino)methylpyridine has been found to work as an effective catalyst toward the formation of ammonia from molecular dinitrogen under ambient conditions.

  hydride HOs3(CO)9[μ-CH2(NC5H3)CH2PPh2]. The PN ligand in 7 undergoes P–C bond activation in toluene at 110 °C to afford the 50e cluster Os3(CO)9(μ-C6H4)(μ-PPh) (9), which contains face-capping benzyne and phosphinidene moieties. The bonding between the benzyne moiety and the opened Os3 frame in 9 has been examined computationally, and these data are discussed relative to σ and π bonding contributions

  κ2‐C,N‐κ1‐P ligand with a carbanionic methine carbon atom directly bound to rhodium as part of a four‐membered Rh‐N‐C‐C rhodacycle. This dimer undergoes meta‐pyridine C−H activation facilitated by weak bases, which leads to a desymmetrization of the system and provides a σ,π‐bridging 3‐pyridyl fragment bound to RhI. The facile Si−C cleavage strategy may pave the way to studying the reactivity and functionalization

STM-break junction measurements of Au-syn-1-Au (Au: gold electrode) revealed high single-molecule conductance (1.9 × 10–2 G0), which is comparable to that of Au-2-Au. Calculations on the basis of the DFT-non equilibrium Green’s function method also support the experimental results. Notably, the molecular

• Study of the Bonding Properties of the New Ligands C₅H₃N(2-R‘)(6-CH₂PPhR) toward Rhodium(I). Evidence for a Dynamic Competition for Bonding between O- and N-Donor Centers When R = <i>o</i>-Anisyl, R‘ = Me

  The bonding properties of the optically active chiral-at-P polydentate ligands C5H3N(2-R')(6-CH2PPhR) (R = Me, R' = H, Me; R o-anisyl, R' = H, Me) and the achiral ligand C5H3N(2-Me)(6-CH2PPh2) toward (COD)Rh+ are reported. The results show that steric hindrance of the 2-position of the pyridyl ring induces a labile character of the Rh-N bond. Moreover, for R = o-anisyl and R' = Me, a dynamic competition for bonding between the N-and O-donating centers is observed. Comparison of the solid state structures of complexes [Rh(COD)(C5H4N(2-CH2PPhMe)][BF4] and [Rh(COD)(C5H3N(2-Me)(6-CH2PPh2)][BF4] shows a significant bond lengthening of the Rh-N bond in the latter complex, consistent with its fluxional behavior observed in solution.
