This study describes the structural study of a highly versatile Ru-NHC (N-heterocyclic carbene) catalyst complex, which was established for the asym. hydrogenation of various aromatic compounds A complex containing an unusual doubly deprotonated NHC ligand was isolated and identified as the precatalyst to this complex. By monitoring its subsequent reactivity, two addnl. precatalysts, featuring partially hydrogenated naphthyl substituents were characterized spectroscopically. Ligand hydrogenation appears to be a key activation process en route to the active catalyst. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Electric Literature of C9H8S).

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.

Sterically crowding the bridge of dithienylcyclopentenes for enhanced photoswitching performance was written by Goestl, Robert;Kobin, Bjoern;Grubert, Lutz;Paetzel, Michael;Hecht, Stefan. And the article was included in Chemistry – A European Journal in 2012.Name: 2-Methylbenzo[b]thiophene This article mentions the following:

Diarylethenes (DAEs) are photochromic mols. with outstanding physicochem. properties. They are ideal for incorporation into materials for optoelectronics because of their superior switching properties. DAEs undergo a reversible 6p electrocyclic reaction upon irradiation with light. The efficiency of the photocyclization reaction is governed by its quantum yield, which is dependent on the equilibrium between the parallel (p) and the antiparallel (ap) conformation. Steric repulsion, which is largely independent of the environment, can also be used to influence the equilibrium between p and ap conformation. Herein, we report a synthetically straightforward method for introducing bulky substituents into the bridge moiety of dithienylcyclopentenes, thus leading to derivatives exhibiting higher photocyclization quantum yield. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Name: 2-Methylbenzo[b]thiophene).

2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures.

Sulfur Transformation Characteristics and Mechanisms during Hydrogen Production by Coal Gasification in Supercritical Water was written by Liu, Shanke;Li, Linhu;Guo, Liejin;Jin, Hui;Kou, Jiajing;Li, Guoliang. And the article was included in Energy & Fuels in 2017.Computed Properties of C9H8S This article mentions the following:

Coal supercritical water gasification (SCWG) is famous for generating clean gas without SO_x pollutant. Study of sulfur transformation characteristics can provide the basis of sulfur removal during hydrogen production by coal gasification in supercritical water (SCW) at the source. In this work, two coals produced from Linfen and Zhangjiamao in China (hereinafter to be referred as L-coal and Z-coal), were chosen as exptl. feedstocks to investigate sulfur transformation characteristics during hydrogen production by coal gasification in SCW (550-750 °C, 20 min, 25 MPa). Sulfur transformation pathway and sulfur forms in the products were complex but detected comprehensively. H₂S was the only gaseous product instead of SO_x, whereas SO₄^2- was the main liquid-sulfur product. Inorganic and organic sulfur compounds were used to investigate sulfur transformation mechanisms. H₂S had three sources as follows. First, among inorganic sulfur of raw coal, FeS₂ (Pyrite) was chem. stable in SCW lacking of hydrogen. When FeS₂ was in hydrogen atm., H₂S was generated and FeS₂ was converted to Fe_1-xS and Fe₃O₄ under SCW. Second, H₂S came from unstable sulfate minerals such as FeSO₄ which may decompose and be converted to Fe₃O₄. Third, organic sulfur, especially thiophene sulfur transformed to H₂S. The two sulfur products H₂S and SO₄^2- depend on H or OH free radical in SCW. More H free radical provided a reducing environment of SCW to generate H₂S at higher temperatures, whereas more OH radical provided an oxidizing environment of SCW to generate SO₄^2- at lower temperatures, but the final trend was generating H₂S when coal gasified completely at a higher temperature The results of this study may provide an exptl. basis of solving the SO_x emission from coal at the source and demonstrate a promising clean utilization way of coal. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Computed Properties of C9H8S).

Plant homeodomain (PHD) finger containing proteins are important epigenetic regulators and are of interest as potential drug targets. Inspired by the amiodarone derivatives reported to inhibit the PHD finger 3 of KDM5A (KDM5A(PHD3)), a set of compounds were synthesized. Amiodarone and its derivatives were observed to weakly disrupt the interactions of a histone H3K4me3 peptide with KDM5A(PHD3). Selected amiodarone derivatives inhibited catalysis of KDM5A, but in a PHD-finger independent manner. Amiodarone derivatives also bind to H3K4me3-binding PHD-fingers from the KDM7 subfamily. Further work is required to develop potent and selective PHD finger inhibitors.

Oxidative diversification of amino acids and peptides by small-molecule iron catalysis was written by Osberger, Thomas J.;Rogness, Donald C.;Kohrt, Jeffrey T.;Stepan, Antonia F.;White, M. Christina. And the article was included in Nature (London, United Kingdom) in 2016.Computed Properties of C9H8S This article mentions the following:

Secondary metabolites synthesized by non-ribosomal peptide synthetases display diverse and complex topologies and possess a range of biol. activities. Much of this diversity derives from a synthetic strategy that entails pre- and post-assembly oxidation of both the chiral amino acid building blocks and the assembled peptide scaffolds. The vancomycin biosynthetic pathway is an excellent example of the range of oxidative transformations that can be performed by the iron-containing enzymes involved in its biosynthesis. However, because of the challenges associated with using such oxidative enzymes to carry out chem. transformations in vitro, chem. syntheses guided by these principles have not been fully realized in the laboratory Here we report that two small-mol. iron catalysts are capable of facilitating the targeted C-H oxidative modification of amino acids and peptides with preservation of α-center chirality. Oxidation of proline to 5-hydroxyproline furnishes a versatile intermediate that can be transformed to rigid arylated derivatives or flexible linear carboxylic acids, alcs., olefins and amines in both monomer and peptide settings. The value of this C-H oxidation strategy is demonstrated in its capacity for generating diversity: four ‘chiral pool’ amino acids are transformed to twenty-one chiral unnatural amino acids representing seven distinct functional group arrays; late-stage C-H functionalizations of a single proline-containing tripeptide furnish eight tripeptides, each having different unnatural amino acids. Addnl., a macrocyclic peptide containing a proline turn element is transformed via late-stage C-H oxidation to one containing a linear unnatural amino acid.

A procedure is developed for the determination of more than 60 individual sulfur-containing compounds (SCC) in liquid hydrocarbon raw materials and in liquid fuels using gas chromatog. on a 25-m WCOT column, inner diameter 0.32 mm, with a nonpolar dimethylpolysiloxane stationary phase (layer thickness 5 μm) and chemiluminescence detection. SCC were identified by individual standard substances and published data. Quant. determination was carried out by the internal standard method. The results of determination of individual SCC in petrol and stable gas condensate are presented.
