The reaction of 1,1′-bis(diphenylphosphino)ferrocene (dppf) with a mixture of [MnRe(CO)10], MeOH and Me3NO afforded the complexes fac-[MnH(CO)3(eta2-dppf)] and [Re2(mu-OMe)2(mu-dppf) (CO)6]. In the one-pot reaction of [Re2(CO)10] with Me3NO, MeOH and dppf, the major mononuclear Re species isolated was the CO2-inserted complex fac-[Re{OC(O)OMe}(CO)3(eta2-dppf)], the crystal structure of which was determined. The coordination sphere of the rhenium atom is roughly octahedral, consisting of an oxygen atom from the methyl carbonate ligand, two phosphorus atoms from a chelating dppf ligand, and three carbon atoms from a facial arrangement of three terminally bonded carbonyls. Analogous Me3NO-mediated methoxylation reactions involving [Os3(CO)12] were also investigated. With a [Me3NO]:[Os3(CO)12] ratio of 2:1, the major product is [Os3(CO)10(mu-H)(mu-Ome)]. With three molar equivalents of Me3NO, significant quantities of [Os3(CO)10(mu-OMe)2] are also obtained. (C) 2000 Elsevier Science Ltd.

X-Ray photoelectron spectra of M(CO)n(eta1-dppf) (n = 5, M = Cr, 1, MO, 2, w, 3; n = 4, M = Fe, 4), (OC)4Fe(mu-dppf)Mo(CO)5, 5, (OC)5M(mu-dppf)M(CO)5 (M = Cr, 6, Mo, 2, W, 8) and 1,1′-bis(diphenylphosphino)ferrocene (dppf), 9, suggested that the technique can be diagnostic for pendant and coordinated phosphines, and, in heterometallic cases, be used to differentiate phosphines bound to different metals.The resolution of the P(2p) bands permits a measurement of the relative binding energies for chemically distinct phosphorus sites in the same complex thus eliminating complications in calibration as well as sample charging problems normally associated with X-ray photoelectron spectroscopy in comparative studies.

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. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2.

[n]Cycloparaphenylenes (n = 8-13, CPPs) were synthesized, and their physical properties were systematically investigated. [8] and [12]CPPs were selectively prepared from the reaction of 4,4?-bis(trimethylstannyl) biphenyl and 4,4?-bis(trimethylstannyl)terphenyl, respectively, with Pt(cod)Cl2 (cod = 1,5-cyclooctadiene) through square-shaped tetranuclear platinum intermediates. A mixture of [8]-[13]CPPs was prepared in good combined yields by mixing biphenyl and terphenyl precursors with platinum sources. Products were easily separated and purified by using gel permeation chromatography. In 1H NMR spectra, the proton of the CPPs shifts to a lower field as n increased due to an anisotropic effect from the nearby PP moieties. Although the UV-vis spectra were rather insensitive to the size of the CPPs, the fluorescence spectra changed significantly in relation to their size. A larger Stokes shift was observed for the smaller CPPs. Redox properties of the CPPs were measured for the first time by using cyclic voltammetry, and the smaller CPPs had lower oxidation potentials. The results are consistent with the HOMO energies of CPPs, of which the smaller CPPs had higher energies.

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.

Treatment of Ru(PPh3)3HCl with the pincer phosphines 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (xantphos), bis(2- diphenylphosphinophenyl)ether (DPEphos), or (Ph2PCH 2CH2)2O affords Ru(P-O-P)(PPh3)HCl (xantphos, 1a; DPEphos, 1b; (Ph2PCH2CH2) 2O, 1c). The X-ray crystal structures of 1a-c show that all three P-O-P ligands coordinate in a tridentate manner through phosphorus and oxygen. Abstraction of the chloride ligand from 1a-c by NaBAr4F (BAr4F = B(3,5-C6H3(CF 3)2)4) gives the cationic aqua complexes [Ru(P-O-P)(PPh3)(H2O)H]BAr4F (3a-c). Removal of chloride from 1a by AgOTf yields Ru(xantphos)(PPh3)H(OTf) (2a), which reacts with water to form [Ru(xantphos)(PPh3)(H 2O)H](OTf). The aqua complexes 3a-b react with O2 to generate [Ru(xantphos)(PPh3)(eta2-O2)H] BAr4F (5a) and [Ru(DPEphos)(PPh3) (eta2-O2)H]BAr4F (5b). Addition of H2 or N2 to 3a-c yields the thermally unstable dihydrogen and dinitrogen species [Ru(P-O-P)(PPh3)(eta2-H 2)H]BAr4F (6a-c) and [Ru(P-O-P)(PPh 3)(N2)H]BAr4F (7a-c), which have been characterized by multinuclear NMR spectroscopy at low temperature. Ru(PPh3)3HCl reacts with 1,1?-bis(diphenylphosphino) ferrocene (dppf) to give the 16-electron complex Ru(dppf)(PPh3)HCl (1d), which upon treatment with NaBAr4F, affords [Ru(dppf){(eta6-C6H5)PPh2}H] BAr4F (8), in which the PPh3 ligand binds eta6 through one of the PPh3 phenyl rings. Reaction of 8 with CO or PMe3 at elevated temperatures yields the 18-electron products [Ru(dppf)(PPh3)(CO)2H]BArF4 (9) and [Ru(PMe3)5H]BAr4F (10).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 1,1-Bis(diphenylphosphino)ferrocene, you can also check out more blogs about12150-46-8

(Chemical Equation Presented) Here we report the electrocatalytic reduction of protons to hydrogen by a novel S2P2 coordinated nickel complex, [Ni(bdt)(dppf)] (bdt = 1,2-benzenedithiolate, dppf = 1,1?-bis(diphenylphosphino)ferrocene). The catalysis is fast and effi cient with a turnover frequency of 1240 s-1 and an overpotential of only 265 mV for half activity at low acid concentrations. Furthermore, catalysis is possible using a weak acid, and the complex is stable for at least 4 h in acidic solution. Calculations of the system carried out at the density functional level of theory (DFT) are consistent with a mechanism for catalysis in which both protonations take place at the nickel center.
