In a patent，Which mentioned a new discovery about 1273-86-5

Comparative analysis of the specific features of autooxidation of ferrocenylacetic acid (FcCH2COOH) in organic solvents at 30-50C in the absence and in the presence of trifluoroacetic acid (processes 1 and 2 respectively) was carried out. It was shown that both reactions proceed as a sequence of two macrostages, the molecular and the chain radical oxidation of the metal complex. Introduction of acid (HX) in the reaction mixture leads to a significant increase in the rate of the process, in the amount of oxygen per one mole of metal complex absorbed by the reaction mixture, and to the change in the yields of main reaction products like hydroxymethylferrocene, formylferrocene, ferrocenylpyruvic acid, and CO2. On the basis of results of the investigation performed, the kinetic and thermodynamic analysis of primary reactions of the process probable mechanisms of both macrostages in both processes were suggested. The significant effect of approach and orientation on the rate of the molecular oxidation of complex as the bifunctional reagent was noted. An assumption was made that the acid takes place in the molecular oxidation of FcCH2COOH according to two alternative mechanisms differing by the way of its coordination with O2 and the metal complex in the prereactional intermediates. The oxidative transformation of these intermediates leads to the generation of radicals of different nature, Fc+?CH2C(O)OO? and HO 2 ? which initiate the chain radical oxidation of the metal complex.

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, 1271-48-3, molcular formula is C12H10FeO2, belongs to iron-catalyst compound, introducing its new discovery., Computed Properties of C12H10FeO2

From the reaction of [PtCl2(N-CMe)2] with FcC-N (1) (Fc = Fe(eta5-C5H4)(eta5-C 5H5)) complex [PtCl2(FcC-N)(N-CMe)] (2) was obtained, which on subsequent treatment with 1 gave trans-[PtCl 2(N-CFc)2] (trans-3). The latter complex and the appropriate cis isomer (cis-3) were also accessible when [PtCl2] or [PtCl2(N-CMe)2] is reacted with a 2.6-fold excess of 1. Appropriate treatment of [PtCl2(N-CMe)2] with two equivalents of 1-acetyl-1′-cyanoferrocene (4) produced trans-[PtCl 2(Fe(eta5-C5H4CN)( eta5-C5H4C(O)Me))2] (trans-5). Coordination polymer [PtCl2(Fe(eta5-C5H 4CN)2)]n (7) was obtained by combining [PtCl2(N-CPh)2] with [Fe(eta5-C 5H4CN)2] (6). However, when 7 was reacted with PPh3 for deaggregation, [PtCl2(PPh3) 2] was formed. Addition of FcC-CLi (8-Li) to trans-3 gave pentametallic trans-[Pt(C-CFc)2(NH-CnBuFc)2] (10) via trans-[Pt(C-CFc)2(N-CFc)2] (9). When trans-3 is reacted with two equivalents of nBuLi in the absence of FcC-CH (8), trans-[PtCl2(NH-CnBuFc)2] (11) was obtained, which decomposed to FcC(-NH)nBu (12), giving FcC(O)nBu (13). Electrochemical measurements of the nitrile platinum complexes show no redox separation for the oxidation of the Fc and Fe(eta5-C 5H4)2 moieties. Compared with the noncoordinated ferrocenecarbonitriles, a shift to higher potentials is observed. In contrast, for 10 four well-separated redox events (-185, -90, +460, +545 mV) were found, which could be assigned to the oxidation of the Fc units. UV-vis/NIR spectroscopy allowed to determine an IVCT absorption (numax = 6495 cm-1, epsilonmax = 270 L·mol-1·cm-1, Deltanu1/2 = 2270 cm-1) for 10+, classifying this mixed-valent species as a weakly coupled class II system according to Robin and Day, while no IVCT transitions were observed for 10n+ (n = 2, 3). The structures of trans-3, cis-3, 10, and FcC(O)tBu (15) in the solid state were determined by single-crystal X-ray diffraction. Although the bond distances and angles of trans-3 and cis-3 are similar, the cis isomer crystallizes as a dimer possessing Pt-Pt distances within the sum of the van der Waals radii.

Chemistry involves the study of all things chemical – chemical processes, SDS of cas: 1271-51-8, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.

The dimesitylphosphinocyclopentene/HB(C6F5)2-derived vicinal trans-1,2-P/B frustrated Lewis pair (FLP) 4 shows no direct phosphane?borane interaction. Toward some reagents it behaves similar to an intermolecular FLP; it cleaves dihydrogen, deprotonates terminal alkynes, and adds to organic carbonyl compounds including CO2. It shows typical intramolecular FLP reaction modes (cooperative 1,1-additions) to mesityl azide, to carbon monoxide, and to NO. The latter reaction yields a persistent P/B FLPNO nitroxide radical, which undergoes H-atom abstraction reactions. The FLP 4 serves as a template for the CO reduction by [HB(C6F5)2] to generate a FLP-eta2-formylborane. The formylborane moiety is removed from the FLP template by reaction with pyridine to yield a genuine pyridine stabilized formylborane that undergoes characteristic borane carbaldehyde reactions (Wittig olefination, imine formation). Most new products were characterized by X-ray diffraction.

The reaction of Cp?2Zr(OtBu)Me (Cp? = C5H4Me) and [Ph3C][B(C6F 5)4] yields the base-free complex [Cp? 2Zr(OtBu)][B(C6F5)4] (6), which exists as Cp?2Zr(OtBu)(CIR)+ halocarbon adducts in CD2Cl2 or C6D 5Cl solution. Addition of alkenes to 6 in CD2Cl 2 solution at low temperature gives equilibrium mixtures of Cp?2- Zr(OtBu)(alkene)+ (12a-l), 6, and free alkene. The NMR data for 12a-l are consistent with unsymmetrical alkene bonding and polarization of the alkene C=C bond with positive charge buildup at Cint and negative charge buildup at Cterm. These features arise due to the lack of d-pi* back-bonding. Equilibrium constants for alkene coordination to 6 in CD2Cl2 at -89 C, K eq = [12][6]-1[alkene]-1, vary in the order: vinylferrocene (4800 M-1) ? ethylene (7.0) ? alpha-olefins > cis-2-butene (2.2) > trans-2-butene (<0.1). Alkene coordination is inhibited by sterically bulky substituents on the alkene but is greatly enhanced by electron-donating groups and the beta-Si effect. Compounds 12a-l undergo two dynamic processes: reversible alkene decomplexation via associative substitution of a CD2Cl2 molecule, and rapid rotation of the alkene around the metal-(alkene centroid) axis.

Introducing a new discovery about 1273-86-5, Name is Ferrocenemethanol

Graphene quantum dots (GQDs), derived from functionalized graphene precursors are graphene sheets a few nanometers in the lateral dimension having a several-layer thickness. They are zero-dimensional materials with quantum confinement and edge site effects. Intense research interest in GQDs is attributed to their unique physicochemical phenomena arising from the sp2- bonded carbon nanocore surrounded with edged plane functional moieties. In this work, GQDs are synthesized by both solvothermal and hydrothermal techniques, with the optimal size of 5 nm determined using high-resolution transmission electron microscopy, with additional UV-Vis absorption and fluorescence spectroscopy, revealing electronic band signatures in the blue-violet region. Their potential in fundamental (direct electron transfer) and applied (enzyme-based glucose biosensor) electrochemistry has been practically realized. Glucose oxidase (GOx) was immobilized on glassy carbon (GC) electrodes modified with GQDs and functionalized graphene (graphene oxide and reduced form). The cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy are used for characterizing the direct electron transfer kinetics and electrocatalytical biosensing. The well-defined quasi-reversible redox peaks were observed under various electrochemical environment and conditions (pH, concentration, scan rate) to determine the diffusion coefficient (D) and first-order electron transfer rate (kET). The cyclic voltammetry curves showed homogeneous ion transport behavior for GQD and other graphenebased samples with D ranging between 8.45 × 10?9 m2 s?1 and 3 × 10?8 m2 s?1 following the order of GO < rGO < GQD < GQD (with FcMeOH as redox probe) < GOx/rGO < GOx/GO < HRP/GQDs < GOx/GQDs. The developed GOx-GQDs biosensor responds efficiently and linearly to the presence of glucose over concentrations ranging between 10 muM and 3 mM with a limit of detection of 1.35 muM and sensitivity of 0.00769 muA muM?1·cm?2 as compared with rGO (0.025 muA muM?1 cm?2, 4.16 muM) and GO (0.064 muA muM?1 cm?2, 4.82 muM) nanosheets. The relatively high performance and stability of GQDs is attributed to a sufficiently large surface-to-volume ratio, excellent biocompatibility, abundant hydrophilic edges, and a partially hydrophobic plane that favors GOx adsorption on the electrode surface and versatile architectures to ensure rapid charge transfer and electron/ion conduction (<10 ms). We also carried out similar studies with other enzymatic protein biomolecules on electrode surfaces prepared from GQD precursors for electrochemical comparison, thus opening up potential sensing applications in medicine as well as bio-nanotechnology.

Air-stable primary phosphines were photopolymerized using phosphane-ene chemistry, the phosphorus analogue of the thiol-ene reaction, to fabricate a completely new class of polymer networks. It was demonstrated that the tunable thermal and physical properties accessible using thiol-ene chemistry could also be achieved using an analogous phosphane-ene reaction. At the same time, the presence of the 31P nucleus that is easily observed using NMR spectroscopy allowed the chemical structures of the networks to be directly probed using solid state NMR spectroscopy. Following its incorporation into the network, phosphorus offers the distinct difference and advantage of being able to undergo a diverse array of further derivatization to afford functional materials. For example, the networks were demonstrated to serve as effective oxygen scavengers and to bind transition metals (e.g., Pd). By using the air stable ferrocenyl phosphine (FcCH2CH2)PH2, redox-active networks were produced and these materials could be pyrolyzed to yield magnetic ceramics. Overall, this demonstrates the promise of phosphane-ene chemistry as an alternative to thiol-ene systems for providing functional materials for a diverse range of applications.

Functionalization of ferrocenyl moieties with a cyanovinyl system using a unique solid-state synthetic method led to the formation of donor-acceptor type compounds with wide absorption in the visible region. A DSSC study using the ferrocenyl cyanovinyl compound as a dye with an electrolyte-free fabrication system showed an unprecedented open-circuit voltage (VOC) of 763-841 mV. DFT calculations were carried out to understand an unique electron transfer mechanism for the DSSC device which may be responsible for the high VOC.
