The coordination chemistry of the diphosphine-ketone ligand 2,2′-bis(diphenylphosphino)benzophenone (Phdpbp) with nickel is reported. The ketone moiety does not bind to Ni(II) in the complex (Phdpbp)NiCl2, whereas reduction to Ni(I) or Ni(0) induces η2(C,O) coordination of the ketone to form the pseudotetrahedral complexes (Phdpbp)NiCl and (Phdpbp)Ni(PPh3). DFT calculations indicate that the metal-ketone bond is dominated by π back-donation; hence, Phdpbp functions as a hemilabile acceptor ligand in this series of complexes.

The solid state structure of 2-(diphenylphosphino)phenyllithiun*Et2O has been determined by a single crystal X-ray diffraction study.The crystal consists of dimeric aggregates in which the Li atoms are solvated by an additional diethyl ether molecule.The compound retains the dimeric structure in an apolar solvent (toluene) but in THF it exists in monomeric form.Ab initio calculations indicate a small but significant influence of P-Li interaction on the stability and structure of P-containing organolithium compounds.

The compound has the structure shown in the formula (1), X is O or S, and L is selected from a single bond. A substituted or unsubstituted C5 - C60 arylene group, a substituted or unsubstituted C3 - C60 heteroarylene group, the Ar being selected from one of a substituted or unsubstituted C5 - C60 aryl group, a substituted or unsubstituted C3 - C60 heteroaryl group, and the - L-Ar is not selected from phenyl, biphenyl, or cyano substituted phenyl. When the compound provided by the invention is applied OLED devices, the efficiency of the device can be effectively improved, the driving voltage is reduced, and the compound is a good-performance electronic transmission material.
Ru catalyzed hydrogenation of CO2 to formate under basic and acidic conditions

The hydrogenation of CO2 to MeOH is pertinent to advance future energy schemes. Towards this end, phosophine-ligated Ru catalysts have been shown to achieve this transformation under either acidic or basic conditions. In this manuscript, we screen catalytic conditions for a novel tris(phosphine) ligand with Ru to see if it can facilitate the conversion of CO2 to MeOH under both acidic and basic conditions. With both sets of conditions, we observe hydrogenation of CO2 to formate. This work shows that the same catalytic system can function under both reaction types but is limited to formate production.
