Thermally stable acrylic acid complexes with low-valent nickel or palladium of the type [(L)M(eta2-CH2=CH-COOH)] [1a: M = Ni, L = 1,1?-bis(diphenylphosphanyl)ferrocene (dppf), 1b: M = Ni, L = 1,1?-bis(diisopropylphosphanyl)ferrocene (dippf), 1c: M = Pd, L = dippf] were obtained by reaction of [Ni(cod)2] or [(L)Pd(nb)] with acrylic acid in the presence of the phosphane ligands. X-ray diffraction analysis of 1a and 1c, respectively display that only the olefin part is coordinated. Hydrogen bonds between two carboxyl groups result in dimers in the solid state. The isomeric nickela-cyclic carboxylates of the type [(L)Ni(CH2CH 2COO)] are stable complexes in case of 2a (L = dppf) and 2b (L = dippf) whereas the unstable compound 2c [L = 1,1?-bis(di-tert- butylphosphanyl)-ferrocene (dtbpf)] undergoes fast reductive decoupling to form CO2 and the ethylene complex [(dtbpf)Ni(ethylene)] (3c). The related complex [(dippf)Ni(ethylene)] (3b) was prepared from nickel(0) complexes by ligand exchange reaction. 3b and 3c were characterized by elemental analyses, NMR spectroscopy and X-ray structure analysis of single crystals.

Treatment of the platinum(0) complex [Pt(dppf)(nbe)] [1; dppf = 1,1?-bis(diphenylphosphanyl)ferrocene, nbe = norbornene] with the 1,2-dihydrodisilanes HPh2SiSiPh2H or HMe2SiSiMe2H gave [Pt(SiR2H)2(dppf)] (2, R = Ph; 4, R = Me) by oxidative addition of the Si-Si bond. The bis-silyl complexes 2 and 4 react with H2 to give [Pt(H)(SiR2H)(dppf)] (3, R = Ph; 5, R = Me) and H2SiR2. Adding HPh2SiSiPh2H to the hydrido silyl complex 3, which can also be prepared through Si-H activation of H2SiPh2 at 1, resulted in the regeneration of 2 as well as in the release of H2SiPh2. Treatment of HR2SiSiR2H with H2 (1.7 bar) in the presence of 2 or 4 under moderate conditions led to the catalytic formation of H2SiR2 with TONs up to 25. The catalytic conversions are distinguished by a high selectivity for the hydrogenolysis of the 1,2-dihydrodisilanes, and no significant tendency for redistribution reactions at Si was observed.

A series of new heteroleptic complexes of the form [M(dppf)L] [where dppf = 1,1?-bis(diphenylphosphino)ferrocene; M = Ni(II) (1), Pd(II) (2), Pt(II) (3) and L = p-tolylsulfonyl dithiocarbimate, p-CH3C6H 4SO2NCS2; M = Ni(II) (4), Pd(II) (5), Pt(II) (6) and L = p-chlorobenzene sulfonyl dithiocarbimate, p-ClC6H 4SO2NCS2; M = Ni(II) (7), Pd(II) (8) and L = p-bromobenzene sulfonyl dithiocarbimate, p-BrC6H4SO 2NCS2; M = Ni(II) (9), Pd(II) (10) and L = 1-ethoxycarbonyl-1-cyanoethylene-2,2-dithiolate (ecda), C2H 5OCO(CN)CCS2] have been synthesized and characterized by elemental analysis, spectroscopy (IR,1H, 13C and 31P NMR and UV-Vis.), cyclic voltammetry and single crystal X-ray diffraction and their light harvesting properties have been investigated by using them as photosensitizers in dye sensitized TiO2 solar cells. In these complexes the metal lies at the center of a distorted square planar environment; the distortion varies in the order Pd ? Pt > Ni. Among these, the nickel complexes showed light-to-electrical energy conversion efficiencies close to that shown by Ru dye N719 whereas the corresponding palladium and platinum complexes show inferior efficiencies under similar experimental conditions.

Application of 12150-46-8, An article , which mentions 12150-46-8, molecular formula is C34H28FeP2. The compound – 1,1-Bis(diphenylphosphino)ferrocene played an important role in people’s production and life.

Arylpalladium aryloxide complexes containing sterically and electronically varied phosphine ligands were prepared, and the rates for reductive elimination of diaryl ethers from these complexes were studied to determine the ligand properties that most strongly accelerate this unusual reaction. Electronic and steric effects were probed by preparing monomeric palladium complexes of the type (L)Pd(Ar)(OAr?), in which L = DPPF (1,1?-bis-diphenylphosphinoferrocene), CF3-DPPF (1,1?-bis[di(4-(trifluoromethyl)phenyl)phosphino]ferrocene), and D-t-BPF (1,1?-bis(di-tert-butylphosphino)ferrocene) and Ar = electron-deficient and electron-neutral aryl groups. Direct C-O bond-forming reductive elimination to form diaryl ethers in high yield was observed after warming the complexes that contained an electron-deficient aryl group bound to palladium. The rate constant for C-O bond-forming reductive elimination from the CF3-DPPF-ligand palladium complex was twice that obtained for the analogous DPPF-ligated-complex. Reductive elimination of diaryl ether from the more bulky D-t-BPF complex occurred roughly 100 times faster than from the DPPF complex. Thermolysis of DPPF and CF3-DPPF complexes containing an electron-neutral aryl group did not form diaryl ether. Thermolysis of (D-t-BPF)Pd(Ph)(OC6H4-4-OMe) also did not form diaryl ether and generated the two monophosphines PhP(t-Bu)2 and FcP(t-Bu)2 (di-tert-butylphosphinoferrocene). However, heating of a FcP(t-Bu)2-ligated aryloxide complex containing an electron-neutral, palladium-bound aryl group generated diaryl ether in 10-25% yield. Moreover, heating of this complex in the presence of an excess of P(t-Bu)3 or Ph5FcP(t-Bu)2 or 1 equiv of 2-di-tert-butylphosphino-1,1?-binaphthyl generated diaryl ether in higher, 58-95%, yields. The effect of ligand concentrations on reaction yields implied that exchange of the bulkier ligands with FcP(t-Bu)2 induced the reductive elimination of diaryl ether.

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, category: chiral-phosphine-ligands

The reaction of [(eta6-p-cymene)RuCl2]2 with some bis(phosphane) ligands (dppm, dppe, dppv, dppa, dpp14b, dppf) has been investigated. In general mixtures of products were obtained, although the pendant phosphane complexes [(eta6-p-cymene)RuCl 2(eta1-dppv)] and [eta6-p-cymene)RuCl 2(eta1-dppa)] were isolated and characterized in the solid state by X-ray diffraction. The later complex was obtained in lower yield and undergoes an equilibration reaction resulting in the formation of a dimeric species, where the dppa bridges two ruthenium centres, and uncoordinated phosphane; the bridging species was also structurally characterised in the solid state. In contrast, the reaction of [(eta6-p-cymene)RuCl 2(PPh3)] with dppa in the presence of [NH 4]PF6 results in the formation of [(eta6-p- cymene)RuCl(PPh3(eta1-dppa)]PF6, which is stable in solution. A series of linked ruthenium-borane complexes, viz. [(eta6-p-cymene)RuCl2(eta1-phosphane- BH3)] (phosphane = dppm, dppe, dppv, dppa, dpp14b, dppf) and [(eta6-p-cymene)RuCl(PPh3)(eta1-dppa- BH3)]PF6 have been prepared from isolated pendant phosphane complexes, those generated in situ, or from a preformed phosphane-borane adduct. The solid-state structures of [(eta6-p- cymene)RuCl2(eta1-dppm-BH3)], [(eta6-p-cymene)RuCl2(eta1-dppe-BH 3)] and [eta6-p-cymene)RuCl2(eta 1-dppv-BH3)] have been determined by X-ray diffraction analysis.

Funneling and functionalization of a mixture of lignin-derived monomers into a single high-value chemical is fascinating. Reported herein is a three-step strategy for the production of terephthalic acid (TPA) from lignin-derived monomer mixtures, in which redundant, non-uniform substitutes such as methoxy groups are removed and the desired carboxy groups are introduced. This strategy begins with the hydro-treatment of corn-stover-derived lignin oil over a supported molybdenum catalyst to selectively remove methoxy groups. The generated 4-alkylphenols are converted into 4-alkylbenzoic acids by carbonylation with carbon monoxide. The Co-Mn-Br catalyst then oxidizes various alkyl chains into carboxy groups, transforming the 4-alkylbenzoic acid mixture into a single product: TPA. For this route, the overall yields of TPA based on lignin content of corn stover could reach 15.5 wt %, and importantly, TPA with greater than 99 % purity was obtained simply by first decanting the reaction mixture and then washing the solid product with water.

Several Ru(II) complexes (eta5-C5H4CO2H)Ru(eta2-L)I have been prepared by the hydrolysis of the ester linkage in (eta5-C5H4CO2t-Bu)Ru(eta2-L)Cl with trimethylsilyl iodide. The hydrides (eta5-C5H4CO2H)Ru(eta2-L)H may be prepared by reduction of the iodide complexes in KOH/MeOH solutions followed by acidification. Complexes with several chelating bisphosphine ligands have been prepared in this way. The carboxylate anions [(eta5-C5H4CO2)Ru(eta2-L)H]- are readily protonated by weak acids to give the carboxyCp complexes. The pKa of the carboxy proton of (eta5-C5H4CO2H)Ru(dppe)H (dppe = 1,2-bis(diphenylphosphino)ethane) is 11.3 in DMSO. Protonation of the neutral hydride complex (eta5-C5H4CO2H)Ru(dppf)H gives the cationic dihydride (eta5-C5H4CO2H)Ru(dppf)H+2; the dihydride structure has been confirmed by measuring the T1 of its 1H NMR hydride resonance over a range of temperatures. The oxidations of the halide complexes (eta5-C5H4CO2H)Ru(dppf)I and (eta5-C5H4CO2t-Bu)Ru(dppf)Cl (dppf = 1,1?-bis(diphenylphosphino)ferrocene) have been studied by cyclic voltammetry.
