Feibelman, Peter J. published the artcileWhat Limits Turnover Number in NH₃ Synthesis on a PNP Pincer Molecule?, SDS of cas: 338800-13-8, the publication is Comments on Inorganic Chemistry (2014), 34(1-2), 3-16, database is CAplus.

Abiol. NH₃ synthesis under mild conditions on a PNP [=2,6-bis(di-tert-butyl-phosphinomethyl)pyridine] pincer chelating an Mo(N₂)₃ group has been reported and attributed to a catalytic cycle wherein only the equatorial N₂ is reduced. The present calculations suggest that reduction of axial N₂ ligands was the reason the cycle ended after production of 23 equivalent of NH₃. NH₃ detachment from axial NNH₃ initiates a terminal reaction pathway by leaving an axial nitrido N behind on the Mo. The trans influence of the strong axial nitride bond causes the second axial N₂ to detach from the Mo, with N-Mo-N₂ remaining as a non-catalytic, pincer-chelated group.

Benyettou, Farah published the artcileRedox-Responsive Viologen-Mediated Self-Assembly of CB[7]-Modified Patchy Particles, Formula: C22H18Cl2N2, the publication is Langmuir (2016), 32(28), 7144-7150, database is CAplus and MEDLINE.

Sulfonated surface patches of poly(styrene)-based colloidal particles (CPs) were functionalized with cucurbit[7]uril (CB[7]). The macrocycles served as recognition units for di-Ph viologen (DPV²⁺), a rigid bridging ligand. The addition of DPV²⁺ to aqueous suspensions of the particles triggered the self-assembly of short linear and branched chainlike structures. The self-assembly mechanism is based on hydrophobic/ion-charge interactions that are established between DPV²⁺ and surface-adsorbed CB[7]. DPV²⁺ guides the self-assembly of the CPs by forming a ternary DPV²⁺⊂(CB[7])₂ complex in which the two CB[7] macrocycles are attached to two different particles. Viologen-driven particle assembly was found to be both directional and reversible. Whereas sodium chloride triggers irreversible particle disassembly, the one-electron reduction of DPV²⁺ with sodium dithionite causes disassembly that can be reversed via air oxidation Thus, this bottom-up synthetic supramol. approach allowed for the reversible formation and directional alignment of a 2D colloidal material.

Lee, Kyounghoon published the artcileLigand K-edge XAS, DFT, and TDDFT analysis of pincer linker variations in Rh(I) PNP complexes: reactivity insights from electronic structure, Recommanded Product: 2,6-Bis((di-tert-butylphosphino)methyl)pyridine, the publication is Dalton Transactions (2016), 45(24), 9774-9785, database is CAplus and MEDLINE.

Here we report P K-edge, Cl K-edge, and Rh L₃-edge X-ray absorption spectroscopy (XAS) data for Rh[C₅H₃N-2,6-(XP^tBu₂)₂]Cl, where X = O (^tBuPONOP; 1) or CH₂ (^tBuPNP; 2), I and II, resp. Solid-state XAS data for 1 and 2 were compared to d. functional theory (DFT) and time-dependent d. functional theory (TDDFT) calculations to identify how changing the PNP pincer linker from O to CH₂ affected electronic structure and bonding at Rh(I). Pronounced differences in XAS peak intensities and energies were observed The P K-edge XAS data revealed a large increase in Rh 4d_x2_-y2 and P 3p orbital-mixing (Rh-P σ*) in 1 compared to 2, and pronounced transition energy variations reflected marked differences in orbital energies and compositions By comparison, the Cl K-edge XAS data revealed only subtle differences in Rh-Cl covalency, although larger splitting between the Rh-Cl π* and σ* transitions was observed in 2. Anal. of the occupied MOs from DFT (HOMO, HOMO-1, HOMO-2, and HOMO-3) and comparison to the unoccupied MOs involved in XAS revealed a relatively uniform energy increase (ca. 0.3-0.5 eV) for all five 4d-derived MOs in Rh(^tBuPNP)Cl (2) compared to Rh(^tBuPONOP)Cl (1). The energy shift was relatively invariant with respect to differences in orbital symmetry, bonding type (σ or π), and orbital mixing, which suggested that the increase could be attributed to electrostatic effects. The change in d-orbital energies are consistent with known reactivity differences of Rh(^tBuPONOP)⁺ and Rh(^tBuPNP)⁺ towards CO, H₂, and CH₂Cl₂, and are explained here by considering how d-orbital energies affect covalent L â†?M σ bonding and M â†?L π backbonding.
