Keywords: glycerol alc etherification Lewis acid catalyst. We’ll tell you more about this compound (cas:63295-48-7).

Here we report the homogeneously-catalyzed etherification of glycerol with short chain alkyl alcs. Among the large variety of Bronsted and Lewis acids tested, we show here that metal triflates are not only the most active but are also capable of catalyzing this reaction with an unprecedented selectivity. In particular, in the presence of Bi(OTf)3, the targeted monoalkylglyceryl ethers were obtained with up to 70% yield. Although tested Bronsted acids were also capable of catalyzing the etherification of glycerol with alkyl alcs., they were found however less active and less selective than Bi(OTf)3. By means of counter experiments, we highlighted that the high activity and selectivity of Bi(OTf)3 may rely on a synergistic effect between Bi(OTf)3 and triflic acid, a Bronsted acid that can be released by in situ glycerolysis of Bi(OTf)3. The scope of this methodol. was also extended to other polyols and, in all cases, the monoalkylpolyol ethers were conveniently obtained with fair to good yields.

Computed Properties of C3F9FeO9S3. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Unlike solvation sphere exchange rates of nuclei belonging to the same molecule in the system iron(3+)/DMF. Author is Kaltenmeier, D.; Hertz, H. G..

Proton and 13C NMR relaxation rates 1/T1 and 1/T2 and chem. shifts Δω of paramagnetic solutions of Fe(ClO4)3 in DMF, Fe(SO3CF3)3 in DMF, and FeCl3 in DMF were measured at 220-400 K. Solvation sphere exchange rates were calculated for all 3 constituents of the DMF mols., CHO, CH3,a and CH3,b. The exchange rate of the CHO nuclei is greater by a factor ∼2 than that of the CH3 nuclei; the exchange rates for the Me groups a and b are identical within exptl. uncertainty. The results were established through a detailed anal. and discussion of the temperature dependence of the 1/T1, 1/T2 and Δω data. The non-exchange part of the observed nuclear magnetic relaxation rates is explained within the existing framework of theor. relaxation equations, containing dipole-dipole and scalar interaction terms. This anal. indicated that delocalization of the unpaired electron spin from the Fe3+ ion to DMF mols. beyond the 1st solvation shell occurs, giving rise to a scalar relaxation contribution in the 2nd solvation sphere. In the case of FeCl3/DMF solutions in the presence of various complex species, Fe(DMF)63+, Fe(DMF)5Cl2+…FeCl4-, a new procedure for extracting residence times from the “”fast exchange”” is presented. Interferences with complex equilibrium caused apparent residence time ratios τM(methyl)/τM(formyl) >2.

Author is Jones, Austin L.; De Keersmaecker, Michel; Pelse, Ian; Reynolds, John R..

Homocoupling defects in conjugated polymers often go undetected but may cause significant batch-to-batch variations that ultimately give seemingly identical polymers different material properties. These defects may go easily unnoticed because conjugated polymers are commonly characterized via gel-permeation chromatog. and elemental anal., two techniques that are not able to provide information on monomer incorporation or end groups. NMR spectroscopy has provided evidence of homocoupling defects, but is limited to polymeric repeat units with distinct chem. shifts and little spectral overlap, a luxury unavailable in polymeric dioxythiophenes. Here, matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) was used to characterize different dioxythiophene copolymer (PE2) batches based on 3,4-propylenedioxythiophene (ProDOT) and 2,2′-bis-(3,4-ethylenedioxy)thiophene (biEDOT) to elucidate changes in structure within different polymer batches. It was determined through the anal. of MALDI-TOF mass spectra that excess biEDOT is incorporated into PE2 when using standard direct (hetero)arylation polymerization (DHAP) conditions. It is hypothesized that the high nucleophilicity of biEDOT causes uncontrolled concerted metalation-deprotonation steps in the DHAP catalytic cycle at high temperatures To improve control of the biEDOT incorporation, the reaction temperature was lowered from 140 to 80°C, and a different polymerization procedure was used where the reaction temperature was ramped-up from room temperature Ultimately, incorporation of excess biEDOT was advantageous to the conductivity of oxidatively doped polymer films, with values greater than 200 and 80 S/cm for the high- and low-temperature polymerizations, resp. This work correlates small differences in polymer structure with solid-state conductivity to expose how batch-to-batch variations regarding homocouplings can produce different material properties.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

The depolymerization of lignin into valuable aromatic chems. is one of the key goals towards establishing economically viable biorefineries. In this contribution we present a simple approach for converting lignin to aromatic monomers in high yields under mild reaction conditions. The methodol. relies on the use of catalytic amounts of easy-to-handle metal triflates (M(OTf)x). Initially, we evaluated the reactivity of a broad range of metal triflates using simple lignin model compounds More advanced lignin model compounds were also used to study the reactivity of different lignin linkages. The product aromatic monomers were either phenolic C2-acetals obtained by stabilization of the aldehyde cleavage products by reaction with ethylene glycol or Me aromatics obtained by catalytic decarbonylation. Notably, when the method was ultimately tested on lignin, especially Fe(OTf)3 proved very effective and the phenolic C2-acetal products were obtained in an excellent, 19.3±3.2 wt % yield.

Conductive polymers are a very promising alternative for the fabrication of transparent conductive materials. They have many advantages compared to existing materials, like a low-cost and a high flexibility. However, elec. conductivity still needs to be improved. We report a straightforward solution-based approach for the fabrication of poly(3,4-ethylenedioxythiophene) (PEDOT) thin films with conductivity as high as 6046 ± 510 S cm-1, based on accurate water content control during the polymerization step. The crystallinity improvement is evidenced by GIWAXS characterization, and low temperature elec. conductivity measurements give new insights on the transport mechanisms at stake. This very high conductivity is, to our knowledge, the highest reported value for solution-based synthesis of PEDOT based materials.

Quality Control of Iron(III) trifluoromethanesulfonate. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Structure and Dopant Engineering in PEDOT Thin Films: Practical Tools for a Dramatic Conductivity Enhancement.

Poly(3,4-ethylenedioxythiophene) (PEDOT) is certainly the most known and most used conductive polymer because it is com. available and shows great potential for organic electronic, photovoltaic, and thermoelec. applications. Studies dedicated to PEDOT films have led to high conductivity enhancements. However, an exhaustive understanding of the mechanisms governing such enhancement is still lacking, hindered by the semicrystalline nature of the material itself. In this article, we report the development of highly conductive PEDOT films by controlling the crystallization of the PEDOT chains and by a subsequent dopant engineering approach using iron(III) trifluoromethanesulfonate as oxidant, N-Me pyrrolidone as polymerization rate controller and sulfuric acid as dopant. X-ray diffraction, HRTEM, Synchrotron GIWAXS analyses and conductivity measurements down to 3 K allowed us to unravel the organization, doping, and transport mechanism of these highly conductive PEDOT materials. N-Me pyrrolidone promotes bigger crystallites and structure enhancement during polymerization, whereas sulfuric acid treatment allows the replacement of triflate anions by hydrogenosulfate and increases the charge carrier concentration We finally propose a charge transport model that fully corroborates our exptl. observations. These polymers exhibit conductivities up to 5400 S cm-1 and thus show great promise for room temperature thermoelec. applications or ITO alternative for transparent electrodes.

After consulting a lot of data, we found that this compound(63295-48-7)Quality Control of Iron(III) trifluoromethanesulfonate can be used in many types of reactions. And in most cases, this compound has more advantages.
