Gold-catalyzed intermolecular alkyne oxyarylation for C3 functionalization of benzothiophenes was written by Rist, Paige A.;Grainger, Richard S.;Davies, Paul W.. And the article was included in Organic Letters in 2021.Application of 1195-14-8 This article mentions the following:

C3-selective C-C bond formation on benzothiophenes is challenging, and few direct functionalization methods are available. A gold-catalyzed reaction of alkynes with benzothiophene S-oxides provides regioselective entry into C3-alkylated benzothiophenes with the C7-alkylated isomer as the minor product. This oxyarylation reaction works with alkyl and aryl alkynes and substituted and unsubstituted benzothiophenes. Mechanistic studies identify that sulfoxide inhibits the catalyst [DTBPAu(PhCN)]SbF₆, which also degrades and forms the unreactive complex [(DTBP)₂Au]SbF₆. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Application of 1195-14-8).

Niobium(V) oxido tris-carbamate as easily available and robust catalytic precursor for the selective sulfide to sulfone oxidation was written by Bresciani, Giulio;Gemmiti, Mario;Ciancaleoni, Gianluca;Pampaloni, Guido;Marchetti, Fabio;Crucianelli, Marcello. And the article was included in Molecular Catalysis in 2021.HPLC of Formula: 1195-14-8 This article mentions the following:

The oxidation of the sulfide function promoted by a variety of vanadium compounds has been largely explored, whereas the use of homogeneous catalytic systems based on the heavier group 5 metals remains less explored. We report the use of easily available niobium and tantalum carbamates, i.e. [M(O₂CNMe₂)₅] (M = Nb, 1; M = Ta, 2), [Nb(O₂CNMe₂)₄], 3, [NbO(O₂CNEt₂)₃], 4, and [NbCl₃(O₂CNEt₂)₂], 5, as effective catalysts for the conversion of a series of alkyl aryl and aromatic sulfides into the corresponding sulfones. NMR investigations on the performant niobium catalyst 4 unexpectedly revealed the substantial stability of this compound in the protic catalytic environment, and a plausible catalytic cycle was obtained by DFT studies. The two active catalytic species, i.e. 4 and its minor mono-methoxide derivative, presumably interconvert to each other exploiting the versatile coordination of the carbamato ligand. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8HPLC of Formula: 1195-14-8).

Hierarchical TS-1 zeolite as an efficient catalyst for oxidative desulphurization of hydrocarbon fractions was written by Serrano, D. P.;Sanz, R.;Pizarro, P.;Moreno, I.;Medina, S.. And the article was included in Applied Catalysis, B: Environmental in 2014.Related Products of 1195-14-8 This article mentions the following:

The catalytic oxidative desulphurization (ODS) of S-containing aromatic compounds has been investigated over a hierarchical TS-1 zeolite prepared from silanized protozeolitic units, characterized by having, addnl. to the zeolitic micropores, a secondary porosity within the supermicro/mesopore region. A standard TS-1 sample has been employed as reference catalyst. The influence of both the solvent (n-heptane and acetonitrile) and the oxidizing agent (hydrogen peroxide and tert-butylhydroperoxide, TBHP) was first studied using dibenzothiophene (DBT) as model substrate. In all cases, the catalytic activity exhibited by the hierarchical TS-1 was much higher than that obtained with the conventional TS-1 as a consequence of the improved accessibility caused by the presence of the secondary porosity. A very high desulphurization activity was obtained with the combination of heptane and TBHP, as solvent and oxidant, resp., leading to an almost total DBT conversion. This fact has been attributed to the fully miscibility of the oxidant solution (TBHP in decane) in the organic reaction medium. Moreover, it is noteworthy that, in these conditions, the oxidation product (sulfone) is insoluble in the reaction medium, which facilitates its removal by filtration or centrifugation. Addnl., the oxidation of different aromatic organosulfur compounds [benzothiophene (BT), 2-methylbenzothiophene (2-MBT), 2,5-dimethylthiophene (2,5-DMT) and dibenzothiophene (DBT)] was investigated using the hierarchical TS-1 catalyst. The trend in the conversion values obtained was 2,5-DMT < BT < 2-MBT < DBT. These results indicate that the oxidation conversion is determined by the nucleophilic character of the sulfur atom, and not by the mol. size of the S-containing compound, provided that the steric and diffusional limitations are overcome by the presence of the hierarchical TS-1 porosity. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Related Products of 1195-14-8).

2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. It is also used in the manufacturing of dyes such as thioindigo.Related Products of 1195-14-8

Reversible Photomodulation of Electronic Communication in a π-Conjugated Photoswitch-Fluorophore Molecular Dyad was written by Moreno, Javier;Schweighoefer, Felix;Wachtveitl, Josef;Hecht, Stefan. And the article was included in Chemistry – A European Journal in 2016.Application In Synthesis of 2-Methylbenzo[b]thiophene This article mentions the following:

The extent of electronic coupling between a boron dipyrromethene (BODIPY) fluorophore and a diarylethene (DAE) photoswitch has been modulated in a covalently linked mol. dyad by irradiation with either UV or visible light. In the open isomer, both moieties can be regarded as individual chromophores, while in the closed form the lowest electronic (S₀→S₁) transition of the dyad is slightly shifted, enabling photomodulation of its fluorescence. Transient spectroscopy confirms that the dyad behaves dramatically different in the two switching states: while in the open isomer it resembles an undisturbed BODIPY fluorophore, in the closed isomer no fluorescence occurs and instead a red-shifted DAE behavior prevails. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Application In Synthesis of 2-Methylbenzo[b]thiophene).

On the use of diarylmaleimide derivatives in biological contexts: An investigation of the photochromic properties in aqueous solution was written by Fleming, Cassandra;Remon, Patricia;Li, Shiming;Simeth, Nadja Anita;Koenig, Burkhard;Groetli, Morten;Andreasson, Joakim. And the article was included in Dyes and Pigments in 2017.Related Products of 1195-14-8 This article mentions the following:

A series of photochromic diarylmaleimide derivatives has been synthesized and studied with respect to the photochromic properties in aqueous solution The main rationale is to investigate if these compounds could be used as photoswitchable units in biol. contexts, motivated by the fact that the diarylmaleimide structural motif is identified in many pharmacophores. Thus, photoswitchable variants of this class of compounds could be very useful in the quest for photoactivatable drugs. The photoinduced cyclization reaction (colorization) is suppressed in solvents of high polarity, whereas the ring-opening reaction (decolorization) still occurs with high efficiency. The photochromically active anti-parallel conformer of the open form is more abundant in the asym. substituted derivatives, which in turn favors the formation of the closed isomeric form. The rates of the thermal isomerization reactions have also been assessed, together with the resistance toward thermal degradation Here it was observed that the maleimide derived compounds were not susceptible to the thermally driven reactions (hydrolysis and isomerization). In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Related Products of 1195-14-8).
