Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), SDS of cas: 161265-03-8.

Carboxylic acids and their derivatives are abundant and inexpensive organic and biomass-derived platform molecules, and their conversion into high-value products represents an important goal. Recently, visible-light photoredox decarboxylative coupling reactions have become an important chemical transformation because of their wide substrate scope, mild reaction conditions, high efficiency, and practicability. This review summarizes recent advances in visible-light photoredox decarboxylative coupling strategies, which include the formation of C?C and C?Y (Y=heteroatom) bonds.

A selected group of cationic three-coordinate Au(i)-NHC complexes of the form [Au(NHC)(dppbz)]OTf have been prepared from a commercially available bidentate phosphine. All complexes have been fully characterised by NMR and mass spectroscopy. The [Au(NHC)]+ fragment shows a pronounced tendency to form linear complexes which is confirmed by the molecular structure of [Au(IPr)(dppbz)]OTf in the solid state. The complexes are brightly luminescent and present very high quantum yield values in the solid state. The assignments of the electronic transitions involved in the emissions are of a phosphorescent nature and it is proposed that the origin of the emissions is derived from the ligand (dppbz) to metal-ligand (Au-NHC) charge-transfer (LML?CT) transition.

The alkoxycarbonylation of alpha-chloro ketones with carbon monoxide in alcoholic solvents could be optimized to generate beta-keto esters in high yields using much lower catalyst loadings than previously reported in the literature. Among the different screened parameters, the nature of the ligand proved to be the most crucial one, the Xantphos ligand affording the highest yields. The scope of the reaction could then be extended to a wide variety of chloro ketones with different types of alcohols. Copyright

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, molecular formula is C19H15O2P. In a Article，once mentioned of 17261-28-8, Computed Properties of C19H15O2P

Protein S-nitrosation is an important post-translational modification. However, the detection of S-nitrosation is still problematic because S-nitrosation products, that is, S-nitrosothiols, are unstable species. Here a new reaction which can selectively convert unstable S-nitrosothiols to stable thioethers in one-pot under very mild conditions is reported. This reaction has the potential to be applied in the detection of protein S-nitrosation.

Three near-infrared (NIR) absorbing unsymmetrical perylene diimide D-A-D type dyes containing 6-undecanoxy as donor group were utilized in dye-sensitized nanocrystalline TiO2 solar cells. Structure of the acceptor side of the molecules were improved by adding 4-[2-methyl-5-(cyanoacrylic acid)-3-thienyl]-phenyl (V), 3-carboxy-2-pyridil (VI) and 3-carboxy-2-pyrazyl (VII) moieties attached to one of the N-side of the dye. The relationship between the molecular structure of the acceptor sites of the dyes and the photovoltaic performances were discussed. Electrochemical measurements indicated that band gaps of the dyes were energetically favorable for electron injection from the excited state of the dyes to the conduction band of TiO2 nanoparticles. However, three dyes gave lower conversion efficiency on DSSC applications. Strong electron-withdrawing nature of perylene core might not permit to transfer the photo-generated electrons to the carboxyl groups anchoring to TiO2 surface, and then solar-to-electricity conversion efficiencies of the dyes were reduced.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, COA of Formula: C34H28FeP2

The formation of MeP(O)(OPh)2 by reductive elimination from L2PdMe(P(O)(OPh)2) species has been investigated. The electronic and steric effects of the supporting ligands were investigated by studying reductive elimination reactions from a series of discrete complexes containing nitrogen- and phosphorus-based ligands. The P(O)-C(sp3) bond-forming reaction is slow when the intermediate species contains bidentate nitrogen ligands or small basic monodentate phosphines. Analogous complexes bearing large bite angle diphosphines such as dppf and Xantphos undergo reductive elimination at ambient temperature. The rate of MeP(O)(OPh)2 formation by reductive elimination from (dppf)PdMe(P(O)(OPh)2) is not affected by the identity or concentration of added ligand (excess dppf or PPh3), suggesting that the reductive elimination occurs from a four- or three-coordinate intermediate. When the rate of reductive elimination is slow, protonolysis reactions between L2PdMe(P(O)(OPh)2) intermediates and HP(O)(OPh)2 leads to the formation of bis-phosphonate complexes. The protonolysis reaction can be circumvented by the use of large bite angle phosphines such as dppf and Xantphos, which lead to rapid rates of P(O)-C(sp3) bond formation. These results demonstrate that the formation of P(O)-C(sp3) bonds by reductive elimination from L2PdRP(O)(OR)2 complexes is quite sensitive to the steric bulk of the supporting ligand and the presence of excess hydrogen phosphonate.
