A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P.

Silver doped TiO2 (Ag-TiO2) materials show high activity and good stability in photocatalysis, but the mechanism could not be illustrated clearly due to their imprecise and inhomogeneous characteristics. Ag-doped titanium-oxo clusters (Ag-TOCs) with an exact crystal structure, which are rarely reported, are beneficial for further understanding structure-property relationships. Herein, six new Ag-TOCs with a butterfly-like Ti8Ag2 core have been synthesized through facile solvothermal reactions, in which two Ag ions are successfully linked to the surface of the Ti8 core. Of interest, the Ti6 unit of the Ti8Ag2 core is similar to that found in the anatase structure and may be a promising model for Ag-TiO2 materials. The band gaps of these Ag-TOCs show different values mainly affected by different ligands. DFT calculations revealed that the lowest energy bands of Ag-TOCs are attributed to the Ag-to-TiO core charge transfer bands. Additionally, all Ag-TOCs exhibit good photoelectric response and high photodegradation activity towards organic dyes.

Investigations of anaerobic corrosion of iron over the past years have led to a number of conclusions regarding the mechanisms. In addition several unusual observations related to these corrosion studies were noted. The cathodic depolarization mechanism does not appear too significant. The primary cause appears to be the production of a volatile phosphorous compound by SRB which reacts with iron to form a black precipitate in the medium. The highly reactive phosphorous compound is produced from an organic compound, inositol hexaphosphate, the major source of phosphorous in plants. Other findings include “electrochemical noise”, “hollow whiskers”, and “rusticles”, FeS and Fe3P in tektites and a most unusual attack on glass.

Three tris-bidentate cyclometalated ruthenium complexes with a di(p-anisyl)amino [5(PF6)], di(p-tolyl)amino [6(PF6)], or di(p-chlorophenyl)amino [7(PF6)] substituent on the cyclometalating phenyl ring have been prepared, where the amine nitrogen is in the meta position to the cyclometalated site (bridged through the phen-1,3-diyl unit). The structure of 6(PF6) has been confirmed by single-crystal X-ray diffraction analysis. Two consecutive redox waves are evident at +0.48 and +0.87 V versus Ag/AgCl for 5(PF6), +0.51 and +1.02 V for 6(PF 6), and +0.53 and +1.18 V for 7(PF6), respectively. The first wave is assigned to the Ru(II/III) process, and the second wave is attributed to the N(0/+) process. After one-electron oxidation using SbCl 5, these complexes display distinct absorptions in the near-infrared region, which are assigned to the nitrogen-to-ruthenium intervalence charge-transfer (ICVT) transitions. The energies of the IVCT transitions vary linearly versus the potential splitting of the Ru(II/III) and N(0/+) process. The charge-transfer direction in these complexes is reversed with respect to a previously reported ruthenium-amine system where the amine nitrogen is in the para position to the cyclometalated site (bridged through the phen-1,4-diyl unit).

A diphosphination of arynes with diphosphines has been developed. The reaction of stable aryne precursors, 2-(trimethylsilyl)aryl triflates, with tetraaryldiphosphines proceeds in the presence of fluorine- or carbonate-based activators to deliver the corresponding diphosphinated products, sterically and electronically tuned 1,2-bis(diphenylphosphino)benzene (dppbz) derivatives, which can find wide application in transition metal catalysis and material science. Additionally, preliminary computational studies on the reaction mechanism are also reported.

A novel series of phenoxyacetic acid derivatives was synthesized based on considerations of the three-dimensional structural similarity of YM022 and RP72540. The gastrin/cholecystokinin (CCK)-B and CCK-A receptor antagonist activities of these compounds were evaluated by investigation of their affinities for human gastrin/CCK-B receptors and human CCK-A receptors, respectively.

The last decade has witnessed tremendous advances in the design of anticancer gold complexes containing tertiary phosphines, a class of ligands that have significantly contributed to the development of metal complexes owing to their stabilizing effect. The promising in vitro antiproliferative properties of the phosphine-containing organogold compound auranofin [1-(thio-kS)-2,3,4,6-tetra-O-acetyl-beta-D-glucopyranose](triethylphosphine-kP)gold(I), originally used to treat rheumatoid arthritis, inspired the extensive application of monodentate phosphines in the development of anticancer gold complexes. Meanwhile, the use of diphosphine ligands promoted advances in the preparation of chelated gold complexes as well as mixed-metal and mixed-ligand complexes that have superior anticancer activity. The present report summarizes the current state of knowledge of diphosphine ligands in the development of anticancer gold complexes, and explores challenges and opportunities in designing gold-containing mixed-metal and mixed-ligand complexes that have anticancer action.
