The synthesis and characterization of pyrazole derivatives of general formula [C6H4-4-R-1-{(3,5-Me2-C3N 2)-CH2-(eta5-C5H4) Fe(eta5-C5H5)}] [R = OMe (1a) or H (1b)] with a ferrocenylmethyl substituent are described.The study of the reactivity of compounds 1 with palladium(II) acetate has allowed the isolation of complexes (mu-AcO)2[Pd{kappa2-C,N-C6H 3-4-R-1-[(3,5-Me2-C3N2)-CH 2-(eta5-C5H4)Fe(eta5-C 5H5)]}]2 (2) [R = OMe (2a) or H (2b)] that contain a bidentate [C(sp2, phenyl), N]- ligand and a central “Pd(mu-AcO)2Pd” unit.Furthermore, treatment of 2 with LiCl produced complexes (mu-Cl)2[Pd{kappa2-C,N-C6H 3-4-R-1-[(3,5-Me2-C3N2)-CH 2-(eta5-C5H4)Fe(eta5- C5H5)]}]2 (3) [R = OMe (3a) or H (3b)] that arise from the replacement of the acetato ligands by the Cl-.Compounds 2 and 3 also react with PPh3 giving the monomeric complexes [Pd{kappa2-C,N-C6H3-4-R-1-[(3,5-Me 2-C3N2)-CH2-(eta5- C5H4)Fe(eta5-C5H 5)]}X(PPh3)] {X- = AcO- and R = OMe (5a) or H (5b) or X- = Cl- and R = OMe (6a) or H (6b)}, where the phosphine is in a cis-arrangement to the metallated carbon atom. Treatment of 3 with thallium(I) acetylacetonate produced [Pd{kappa2-C,N-C6H3-4-R-1-[(3,5-Me 2-C3N2)-CH2-(eta5- C5H4)Fe(eta5-C5H 5)]}(acac)] (7) [R = OMe (7a) or H (7b)].

The keto-phosphines (L1), <(Ph2PCH2C(O)(eta5-C5H4))2Fe> (L2) and <(Ph2PCH2C(O)(eta5-C5H4)C(O)CH3)> (L3) were respectively prepared by the reaction of Ph2PCl with the lithium enolates derived from acetylferrocene for L1, and 1,1′-bis(acetyl)ferrocene for L2 and L3.Ligand L1 crystallizes in the space group P1 with a 8.526(2), b 10.915(3), c 12.822(3) Angstroem, alpha 63.75(2), beta 69.04(2), gamma 70.77(2) deg, V 978.4 Angstroem3 and Z 2.The structure was solved and refined to R=0.034 and RW=0.042.The C5-rings are eclipsed (3.2 deg) and the plane of the keto group forms a dihedral angle of 13.1 deg with the C5H4 plane.In the complexes cis- and trans- (cis-1 and trans-1), <(o-C6H4CH2NMe2)PdClL1> (2), cis- (3), and (4) the phosphine ligand(s) behave as P-monodentate(s).The structure of trans-1 has been determined by X-ray diffraction at -145 deg C.The complex crystallizes in the monoclinic space group P21/c with a 10.622(7), b 12.647(7), c 15.59(1) Angstroem, beta 103.20(6) deg, V 2039 Angstroem3 and Z=2.The structure was solved and refined to R=0.037 and RW=0.053.The palladium atom lies on a centre of symmetry and the Pd-P and Pd-Cl bond lengths are respectively 2.314(1) and 2.287(1) Angstroem.The C5-rings of each ligand are slightly staggered (10.5 deg) and, as for L1, each keto group is almost parallel to the C5H4 plane (dihedral angle 8.9 deg).For the complex BF4, NMR and IR solution spectroscopy has shown that there is a dynamic exchange between chelating and P-monodentate L1.The possibility of using L2 as a binucleating ligand was demonstrated by the preparation of the trinuclear complex <((C10H8N)PdCl)2(mu-L2-P,P')> (6).The enolato complexes cis- (M=Pd (7), M=Pt (8)), and <(o-C6H4CH2NMe2)Pd(Ph2PCH=C(O)(eta5-C5H4)Fe(eta5-C5H5))> (9) were prepared in high yield by the reaction of NaH with complexes 1, 3, and 2, respectively.Complex 9 reacts with dimethylacetylenedicarboxylate to yield the alkenyl complex <(o-C6H4CH2NMe2)Pd(Ph2PCH(MeO2CC=CCO2Me))> (10), resulting from carbon-carbon coupling between the P bound enolate-carbon atom and the alkyne.All the complexes were characterized by elemental analysis, and 1H and 31P(1H) NMR and IR spectroscopy.

Introducing a new discovery about 1271-51-8, Name is Vinylferrocene

Abstract New dyes containing pyridine anchoring group and different nitrogen-based heterocyclic electron-donating units linked via benzothiadiazole moiety have been synthesized and characterized by photophysical studies. Incorporation of benzothiadiazole extended the absorption onset into the lower energy region up to 600 nm. The dyes possessing vinyl linker between the heterocyclic donor and benzothiadiazole exhibited red-shifted absorption with high molar extinction coefficient than the dyes, which contain heterocyclic donor directly attached to the benzothiadiazole unit. The dyes exhibited acidochromism in the absorption spectra presumably due to the protonation of the pyridine nitrogen. These materials exhibited good thermal stability and their thermal-decomposition temperatures are in the range, 355-407 C. The dye-sensitized solar cells fabricated using a dye containing phenothiazine donor showed power conversion efficiency of 1.97%. Electrochemical impedance studies reveal that the charge separation is highly dependent on the structural composition of the dyes.

Scanning electrochemical microscopy represents a powerful tool for electro(chemical) characterization of surfaces, but its applicability has been limited in most cases at microscale spatial resolution, and the greatest challenge has been the scaling down to the nanoscale for fabrication and the use of nanometer-sized tips. Here, Pt nanoelectrodes with nanometer electroactive area were fabricated and employed for imaging a distribution of gold nanoparticles (AuNPs) and bioelectrocatalytic activity of a redox-active enzyme immobilized on gold surfaces. [Figure not available: see fulltext.].

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 1273-86-5, and how the biochemistry of the body works.name: Ferrocenemethanol

Reference of 1273-86-5, 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, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery.

A series of several new families of ferrocene-containing imidazolium salts were synthesized by etherification of ferrocene methanol, acylation of ferrocene, and amide coupling of ferrocene carboxylic acid. The etherification was achieved by an acid-catalyzed procedure and very good yields of between 86-93-% were obtained. Next to the nature of the linkage itself, the lengths of the alkyl chains linking the ferrocenyl moiety and the imidazolium group and the nature of the counterions were also varied. Interestingly, a gamma-effect can be observed for the ether compounds but this effect was only visible in 13C NMR spectroscopy. These new redox-active ionic liquids were fully characterized by FTIR, 1H, 19F, and 13C NMR spectroscopy, and by MS, HRMS and elemental analysis. A novel series of ferrocenated ionic liquids with different spacer species between the ferrocenyl moiety and the imidazolium group have been developed. The spacer units have been established by amide coupling, etherification and acylation. The latter reaction is strongly influenced by the chain length of the acid chloride and a gamma-effect is observable for the ether compounds. Copyright

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing.In an article, 12180-80-2, molcular formula is C24H10FeO2, belongs to iron-catalyst compound, introducing its new discovery., Related Products of 12180-80-2

A reaction between cyclopentadienylsodium and ethyl benzoate in refluxing THF produces (benzoylcyclopentadienyl)sodium (4) in 70-80percent yield.Subsequent treatment of 4 in ethanol solution with thallium ethoxide affords (benzoylcyclopentadienyl)thallium (3) in nearly quantitative yield.Reactions of 3 with Mn(CO)5Br, Re(CO)5Br, 2 or FeCl2 lead to the respective eta5-benzoylcyclopentadienyl derivatives of these metals, and demonstrate the utility of 3 in organometallic syntheses.Reactions of several of these organometallic ketones with cymantrenyllithium<(eta5-C5H4Li)Mn(CO)3> provide a useful new route to bimetallic compounds.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 12180-80-2

N-Substituted 2-aza-[3]-ferrocenophanes were easily synthesized from 1,1?-ferrocenedicarbaldehyde and aliphatic amines in high yields. One of the ferrocenophanes served as a ligand for the copper-catalyzed oxidative coupling of 2-naphthol derivatives to give the products in good yields with up to 92% ee, and it also efficiently catalyzed the asymmetric Michael addition reaction as an organocatalyst.
