The synthesis and metal coordination chemistry of a phosphine- and thiolate-substituted ferrocenediyl ligand were discussed. Bridged dimeric species, with the thiolate S adopting a binucleating role were found to be observed for Pd(II) and Rh(I) metal centers while a mononuclear, square planar Ni(II) complex was formed on reaction of the ligand with [Ni-(TMEDA)Me2]. It was found that the rhodium complexes with phosphorus-sulfur donor ligands showed excellent activities and stability as methanol carbonylation catalysts.

Isomeric diborylated ferrocenes featuring 1,1?-, 1,2-, and 1,3-substitution patterns have been targeted via a combination of electrophilic aromatic substitution and directed ortho-lithiation protocols. While none of these systems are competent for the Lewis acid chelation of fluoride, related systems featuring a mixed B/Si acceptor set capture 1 equiv of fluoride via a Si-F-B bridging motif.

Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene

A novel, unsymmetrical 1,1?-disubstituted ferrocenediyl ligand, 1-(diphenylphosphino)-1?-(methoxy)ferrocene (3), featuring phosphine and ether substituents has been synthesized via two different routes and structurally characterized. Its coordination chemistry was investigated by reaction with Rh(I), Cu(I), and group 10 metal precursors. With Ni(II) precursors, chelating complexes are formed in high yield, whereas with Pd(II) and Pt(II) precursors, either chelating complexes or monodentate bis ligand complexes with trans phosphorus ligation may be formed depending on the reaction conditions and metal precursor employed. A similar monodentate trans phosphorus-ligated complex is observed with Rh(I), whereas with Cu(I) precursors, a phosphorus-ligated monodentate bis ligand complex with a coordinated acetonitrile was obtained. Preliminary studies show that 3, in combination with either Pd(II) or Pd(0) precursors, can act as a catalyst for the Suzuki coupling reaction.

The development of a practical synthesis of 1?-(diphenylphosphino)-1-aminoferrocene (2) and its P-borane adduct (2B) allowed the facile preparation of 1?-(diphenylphosphino)-1-isocyanoferrocene (1). This compound combining two specific soft-donor moieties was studied as a ligand for univalent Group 11 metal ions. The reactions of 1 with AgCl at 1:1 and 2:1 molar ratios only led to the coordination polymer [Ag2(mu-Cl)2(mu(P,C)-1)]n (6), while those with Ag[SbF6] provided the dimer [Ag2(Me2CO-kappaO)2(mu(P,C)-1)2][SbF6]2 and the quadruply-bridged disilver complex [Ag2(mu(P,C)-1)4][SbF6]2 (8), respectively. Addition of 1 to [AuCl(tht)] (tht = tetrahydrothiophene) afforded the mono- and the digold complex, [AuCl(1-kappaP)] (9) and [(mu(P,C)-1)(AuCl)2] (10), depending on the reaction stoichiometry. Finally, the reaction of 1 with [Au(tht)2][SbF6] or halogenide removal from 9 with AgNTf2 led to cationic dimers [Au2(mu(P,C)-1)2]X2 (11, X = SbF6 (a) or NTf2 (b)). Catalytic tests in the Au-mediated isomerization of (Z)-3-methylpent-2-en-4-yn-1-ol to 2,3-dimethylfuran revealed that 11a and 11b are substantially less catalytically active than their analogues containing 1?-(diphenylphosphino)-1-cyanoferrocene as the ligand, most likely due to a stronger coordination of the isonitrile moiety, which prevents dissociation of the dimeric complexes into catalytically active monomeric species.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1293-65-8, and how the biochemistry of the body works.HPLC of Formula: C10Br2Fe

Application of 1293-65-8, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. In a document type is Article, and a compound is mentioned, 1293-65-8, name is 1,1′-Dibromoferrocene, introducing its new discovery.

We report the synthesis of mono- and 1,1?-difluoro-substituted metallocenes (ferrocene, ruthenocene) and of asymmetrical 1,1?-disubstituted ferrocenes with one substituent being fluorine. Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the experimental conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1?-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, respectively. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I). Finally, 1-bromo-1′-fluoro-ferrocene turns out to be an ideal starting material for further fluoro-substituted ferrocene derivatives.

Fe[(C5H4)NHPh]2 (2a) was prepared from 1,1?-dibromoferrocene and N-phenylacetamide by an Ullmann reaction and subsequent basic solvolysis of the coupling product Fe[(C5H 4)N(COMe)Ph]2 (1a).

The stereoelectronic influence of phosphine substituents on the coordination and catalytic properties of phosphinoferrocene carboxamides was studied for the model compounds R2PfcCONHMe (1a-d), where fc = ferrocene-1,1?-diyl and R = i-Pr (a), t-Bu (b), cyclohexyl (Cy; c), Ph (d), using experimental and DFT-computed parameters. The electronic parameters were examined via 1JSeP coupling constants determined for R2P(Se)fcCONHMe (6a-d) and C?O stretching frequencies of the Rh(I) complexes trans-[RhCl(CO)(1-kappaP)2] (7a-d); the steric properties of 1a-d were assessed through Tolman?s ligand cone angles (theta) and solid angles (Omega). Generally, a very good agreement between the calculated and experimental values was observed. Whereas the donor ability of the amidophosphines was found to increase from 1d through 1a,c to 1b, the trends in steric demand suggested by the two parameters differed, reflecting the different spatial properties of the phosphine substituents. In situ NMR studies and catalytic tests on the Suzuki-Miyaura cross-coupling of 4-bromoanisole with a bicyclic 4-tolylborate to give 4-methyl-4?-methoxybiphenyl using [Pd(eta2:eta2-cod)(eta2-ma)] (cod = cycloocta-1,5-diene, ma = maleic anhydride) as a Pd(0) precursor revealed that different Pd-1 species (precatalysts) were formed from different ligands and participated in the reaction. Specifically, the bulky and electron-rich donor 1b favored the formation of [Pd(1b)(ma)], while the remaining ligands provided the corresponding bis-phosphine complexes [Pd(1)2(ma)]. The best results in terms of catalyst longevity and efficacy were observed for ligands 1a,c.
