Fe(CF3SO3)2 and Fe(p-MeC6H4SO3)2 were prepared and on the basis of vibrational and electronic spectra and magnetic and Moessbauer data were assigned a layer lattice structure involving hexacoordinated Fe(II) and terdentate bridging anions. The FeO6 chromophore in these compounds is distorted by a trigonal elongation along the C3 axis. Fe(MeSO3)2 was obtained in 2 isomeric forms, 1 having a trigonal elongation of the FeO6 chromophore, the other a trigonal compression. No structural isomerism was found for the other Fe(II) sulfonates; however, evidence for such isomerism in methanesulfonates of Co(II) and Zn(II) is presented. While Fe(CF3SO3)2 and Fe(p-MeC6H4SO3)2 appear to be magnetically dilute, the presence of antiferromagnetic coupling in both forms of Fe(MeSO3)2 is indicated. Fe(CF3SO3)3, Fe(p-MeC6H4SO3)3, and Fe(MeSO3)3 were prepared and all 3 are magnetically concentrated exhibiting magnetic moments which are significantly less than 5.92 μB and which decrease with decreasing temperature

Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about A bioinspired iron catalyst for nitrate and perchlorate reduction, the main research direction is bioinspired iron catalyst nitrate perchlorate reduction water wastewater.Synthetic Route of C3F9FeO9S3.

Nitrate and perchlorate have considerable use in technol., synthetic materials, and agriculture; as a result, they have become pervasive water pollutants. Industrial strategies to chem. reduce these oxyanions often require the use of harsh conditions, but microorganisms can efficiently reduce them enzymically. We developed an Fe catalyst inspired by the active sites of nitrate reductase and (per)chlorate reductase enzymes. The catalyst features a secondary coordination sphere that aids in oxyanion deoxygenation. Upon reduction of the oxyanions, an Fe(III)-oxo is formed, which in the presence of protons and electrons regenerates the catalyst and releases water.

From this literature《A bioinspired iron catalyst for nitrate and perchlorate reduction》,we know some information about this compound(63295-48-7)Synthetic Route of C3F9FeO9S3, but this is not all information, there are many literatures related to this compound(63295-48-7).

The salt Fe(OTf)3 has been shown to function as an effective catalyst in three different reactions, epoxide oxidative ring-opening to an α-hydroxy ketone, urea α-diketone condensation to form glycolurils, and glycoluril diether synthesis by formaldehyde condensation. In each of these reactions, Fe(OTf)3 was compared to Bi(OTf)3, a viable alternative catalyst with few or no prior examples of this type. Differences and advantages are highlighted but in most cases yields were generally high, and both catalysts outperformed conventional acid catalyzed methods.

Related Products of 63295-48-7. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Solution processed intrinsically conductive polymer films with high thermoelectric properties and good air stability. Author is Yao, Hongyan; Fan, Zeng; Li, Pengcheng; Li, Bichen; Guan, Xin; Du, Donghe; Ouyang, Jianyong.

It is important to study thermoelec. (TE) materials because they can directly convert heat into electricity. Although intrinsically conducting polymers have the advantages of nontoxicity, low cost, high mech. flexibility and low thermal conductivity, their thermoelec. properties must be significantly improved for practical application. Here, we report a solution-processed conducting polymer, poly(3,4-ethylenedioxythiophene):trifluoromethanesulfonate (PEDOT:OTf), with very high TE properties. As-prepared PEDOT:OTf films from their precursor solution can exhibit a power factor of 346 ± 39 μW m-1 K-2. The power factor can be further enhanced by a post treatment with NaOH or a reducing agent like glucose or ascorbic acid. The NaOH treatment can give rise to a power factor of 568 ± 64 μW m-1 K-2 with a Seebeck coefficient of 49.2 ± 1.4 μV K-1 and an elec. conductivity of 2342 ± 98 S cm-1. This power factor is higher than those obtained by treatment with the reducing agents. The different power factors by NaOH and reducing agent treatments are attributed to their different effects on the doping. The NaOH treatment can remove the protonic doping while the reducing agents can lower the normal oxidation level of PEDOT. The charge carriers due to protonic acid doping have lower energy, and thus the removal of protonic acid doping can significantly enhance the Seebeck coefficient while not lowering the elec. conductivity too much.

A novel application of highly stable Fe(OTf)3 as an efficient catalyst for a carbon-carbon bond formation by the activation of a terminal alkyne carbon-hydrogen (C-H) bond under solvent-free reaction conditions is described. Notably, this protocol of green synthesis (green chem.), which produced quinolines by a reaction of amines, aldehydes and terminal aryl alkynes, shows attractive characteristics including concise one-pot reaction conditions, high atom economy, very limited energy consumption and the sequential catalytic process requires only a catalytic (5 mol%) amount of Fe(OTf)3 and short reaction time.
