Thallium(III) Trifluoroacetate-Trifluoroacetic Acid in the Chemistry of Polythiophenes. 2. Treatment of 3-Alkylthiophenes and Electron Paramagnetic Resonance Results was written by Tormo, Jordi;Moreno, F. Jesus;Ruiz, Jordi;Fajari, Lluis;Julia, Luis. And the article was included in Journal of Organic Chemistry in 1997.Safety of 3-Ethylthiophene This article mentions the following:

The treatment of thiophene and 3-alkylthiophenes with thallium(III) trifluoroacetate (TTFA) in trifluoroacetic acid (TFA) gives insoluble and dark powdery solids with oxygen content and elec. conductivities ranging from 10-4 to 10-6 Ω-1 cm-1. Polar and short fractions are negligible. All of them show semiconductivity (10-3-10-6 Ω-1 cm-1) when doped in iodine atm. ESR (EPR) spectra of either as-synthesized or I2-treated solids display characteristic single and broad lines (ΔHpp, 1.84-7.4 G) with Lorentzian shapes and g-values in the range 2.0028-2.0038. IR spectra show characteristic C-H out-of-plane deformations (780 cm-1 for polythiophene and 820-825 cm-1 for poly(3-alkylthiophenes)) in addition to a strong peak at 1650-1690 cm-1 which has not been conclusively assigned. EPR spectra of some disubstituted and tetrasubstituted 2,2′-bithiophene radical cations have been observed and their g-values and coupling constants assigned when the corresponding parent compounds are photolyzed with UV light in TFA. Photolysis of 3-alkylthiophenes in TFA in the EPR instrument gave the radical cations of 4,4′-dialkyl-2,2′-bithiophenes. In no case, were EPR signals of the isomeric 3,3′-dialkyl- or 3,4′-dialkyl-2,2′-bithiophene radical cations observed, indicating that dimerization of 3-alkylthiophenes occurs through the less sterically hindered 5-position. The presence of two doublet species corresponding to both conformers, syn and anti, in the radical cations is associated with a large barrier to rotation about the C(2)-C(2′) bond. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Safety of 3-Ethylthiophene).

Structural and quantum chemical analysis of exciton coupling in homo- and heteroaggregate stacks of merocyanines was written by Bialas, David;Zitzler-Kunkel, Andre;Kirchner, Eva;Schmidt, David;Wuerthner, Frank. And the article was included in Nature Communications in 2016.Safety of 3-Ethylthiophene This article mentions the following:

Exciton coupling is of fundamental importance and determines functional properties of organic dyes in (opto-)electronic and photovoltaic devices. Here we show that strong exciton coupling is not limited to the situation of equal chromophores as often assumed. Quadruple dye stacks were obtained from two bis(merocyanine) dyes with same or different chromophores, resp., which dimerize in less-polar solvents resulting in the resp. homo- and heteroaggregates. The structures of the quadruple dye stacks were assigned by NMR techniques and unambiguously confirmed by single-crystal X-ray anal. The heteroaggregate stack formed from the bis(merocyanine) bearing two different chromophores exhibits remarkably different UV/vis absorption bands compared with those of the homo aggregate of the bis(merocyanine) comprising two identical chromophores. Quantum chem. anal. based on an extension of Kasha’s exciton theory appropriately describes the absorption properties of both types of stacks revealing strong exciton coupling also between different chromophores within the heteroaggregate. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Safety of 3-Ethylthiophene).

The influence of hydrocarbon compositions of transformer oils on the electrostatic charging tendency was written by Yu, Hui-min;Ma, Shu-jie;Zhang, Qi;Zhang, Ling-jun. And the article was included in Runhuayou in 2010.Application In Synthesis of 3-Ethylthiophene This article mentions the following:

The results of studies on the electrostatic charging tendency of flowing transformer oils for OF-or OD- cooled super high voltage transformers were summarized. The influence of hydrocarbon compositions of transformer oils on the electrostatic charging tendency was studied in detail, in which the electrostatic charging tendency of naphthenic transformer oils with different aromatic hydrocarbons content, and the electrostatic charging tendency of different crude oil style transformer oils with the same aromatic hydrocarbons content were mostly investigated. The influences of the sulfide compounds, the nitride compounds, as well as poly-aromatics content on the electrostatic charging tendency were also studied. It was found that high poly-aromatics content in transformer oils should increase the electrostatic charging tendency of transformer oils. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Application In Synthesis of 3-Ethylthiophene).

Insights into the Reactivity of Thiophene: Heterogeneous Alkylation was written by Lucarelli, C.;Giugni, A.;Vaccari, A.. And the article was included in Topics in Catalysis in 2016.Category: benzothiophene This article mentions the following:

The importance of thiophene derivatives in the fine chem. industry lies in the use of this class of mols. as raw materials in the synthesis of drugs, fragrances and pesticides. Nowadays, the synthesis of these mols. is multistep and expensive. The gas phase alkylation of thiophene on solid acid catalysts has been deeply studied by focusing on the possibility to control the product distribution of the reaction, paying particular attention to the relative amount of the 2- and 3-alkylthiophene, kinetic and thermodn. products resp. The difficulties in changing the 2:3 isomer ratio have been justified through the comprehension of thiophene behavior on the catalyst surface, that is responsible for the complex adsorption/desorption phenomena. It has been shown that the reaction is mainly affected by the strong adsorption of thiophene on the catalytic sites, with the critical step of the reaction represented by the saturation of the catalyst surface. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Category: benzothiophene).

Characterization of aroma-active compounds and perceptual interaction between esters and sulfur compounds in Xi baijiu was written by Ma, Ning;Yi, Fengping;Zhu, Jiancai.

The aroma-active compounds of three Xi baijiu samples (Xijiulan, Y1, Xijiuyinxiangguizhou, Y2 and Xijiuyinzhi, Y3) were analyzed by gas chromatog.-olfactometry (GC-O), GC-flame photometric detection (FPD) and odor activity value (OAV). The results indicated that a total of 92 aroma compounds were determined, including 16 sulfur compounds Furthermore, 2-methyl-3-furanthiol (OAV: 31-220), 3-mercapohexyl acetate (OAV: 1870), di-Me trisulfide (OAV: 333-400), 3-mercaptohexanol (OAV: 34-36), β-damascenone (OAV: 1317-1342), 2-butylfuran (OAV: 629-672), Et 3-methylbutanoate (OAV: 655-899), Et hexanoate (OAV: 687-729), and Et octanoate (OAV: 1164-1362) exhibited much higher OAVs and aroma intensities (AIs) than other compounds Finally, the perceptual interactions between five sulfur compounds and six esters were studied using Feller’s additive model in Y2. Among the 30 binary mixtures, 12 groups showed an additive effect, 4 groups exhibited a synergistic effect, and 14 groups exerted a masking effect. These data indicated that di-Me disulfide and 2-methyl-3-furanthiol had masking and additive effects on the aroma of esters.
