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.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.VanAtta, Reuel B.; Franklin, Catherine C.; Valentine, Joan Selverstone researched the compound: Iron(III) trifluoromethanesulfonate( cas:63295-48-7 ).Application In Synthesis of Iron(III) trifluoromethanesulfonate.They published the article 《Oxygenation of organic substrates by iodosylbenzene catalyzed by soluble manganese, iron, cobalt, or copper salts in acetonitrile》 about this compound( cas:63295-48-7 ) in Inorganic Chemistry. Keywords: epoxidation olefin iodosylbenzene mechanism; metal nitrate triflate catalyst epoxidation. We’ll tell you more about this compound (cas:63295-48-7).

Reaction of PhIO with (Z)- (I) and (E)-stilbene (II), Me2C:CMe2 or cyclohexene in the presence of catalytic amounts of metal nitrates and triflates (metal = Fe2+, Fe3+, Mn2+, Cu2+) gave epoxidation in moderate to high yields. The same systems oxidize cumene to PhCMe2OH in moderate yields. All of the metal salt-PhIO reactions with II gave 16-86% I oxide, while reactions with I gave mixtures of II 0-82, I oxide 0-51%, and II oxide 4-51%. Some cleavage products were also observed Qual. comparisons of the epoxidation of the stilbenes catalyzed by M(O3SCF3)3 (M = Fe, Mn) with those catalyzed by the same metal porphyrins showed that the yields of the triflate- and porphyrin-catalyzed reactions were comparable for each metal ion. The triflates react more rapidly with II than with I, while the reverse was true for the porphyrins. Thus, the porphyrin ligand is not required for metal-ion catalysis of oxygenations of organic substrates by PhIO.

Synthetic Route of C3F9FeO9S3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms.

Author is Rahaman, Mohammad Shahinur; Tulaphol, Sarttrawut; Molley, Ashten; Mills, Kyle; Hossain, Anwar Md.; Yelle, Daniel; Maihom, Thana; Sathitsuksanoh, Noppadon.

Catalytic pathways to produce high carbon number compounds from benzyl Ph ether require multiple steps to break the aryl etheric carbon-oxygen bonds; these steps are followed by energy-intensive processes to remove oxygen atoms and/or carbon-carbon coupling. Here, we show an upgrading strategy to transform benzyl Ph ether into large phenolic (C12-C22) compounds by a one-step C-O breaking and C-C coupling catalyzed by metal triflates under a mild condition (100°C and 1 bar). Hafnium triflate was the most selective for the desired products. In addition, we measured the effect of solvent polarity on the catalytic performance. Solvents with a polarity index of less than 3.4 promoted the catalytic activity and selectivity to C12-C22 phenolic products. These C12-C22 phenolic compounds have potential applications for phenol-formaldehyde polymers, diesel/jet fuels, and liquid organic hydrogen carriers.
