《Functionalization of SBA-15 mesoporous materials with 2-acetylthiophene for adsorption of Cr(III) ions》 was published in Microporous and Mesoporous Materials in 2020. These research results belong to Wu, Hongmei; Xiao, Yu; Guo, Yu; Miao, Shiju; Chen, Qiangqiang; Chen, Zan. Electric Literature of C6H6OS The article mentions the following:

SBA-15 mesoporous materials functionalized with 2-acetylthiophene-derived Schiff’s base denoted as A-SBA-15, were synthesized for removal of Cr(III) ions from aqueous solution The adsorbent materials were characterized by XRD, SEM, TEM, N2 adsorption-desorption, TGA, EDXS, FTIR, 13C CP-MASNMR and XPS. Tests were then performed to study the adsorption of Cr(III) ions onto A-SBA-15 in batch systems. The maximum adsorption capacity of A-SBA-15 (114.2 mg/g) for Cr(III) ions was much higher than that of the pure SBA-15 (15.6 mg/g). The kinetics anal. revealed that the adsorption process was well described by pseudo-second-order kinetic model. The Langmuir isotherm model was better fitted with the adsorption data for Cr(III) compared to the Freundlich isotherm model. Also, the Cr(III) adsorption onto A-SBA-15 is spontaneous, endothermic, and mainly chem. adsorption as shown by the study of various thermodn. parameters, such as, ΔG°, ΔH°, and ΔS°. The characterization of A-SBA-15 materials before and after adsorption of Cr(III) ions showed that the chem. combination of the organic groups on A-SBA-15 and Cr(III) ions through coordination bond. The as-prepared A-SBA-15 materials could be reused in 5 successive recycles without significantly decreasing its adsorption capacity. Also, 4 batches of A-SBA-15 prepared at different synthesis times have the similar adsorption capacity. Besides, the adsorbent showed good selective separation of Cr(III) ion in the presence of Cu(II), Zn(II) and Ni(II) ions. The good reproductivity, reusability and selectivity suggest that A-SBA-15 material can be used as a promising adsorbent for efficient removal of heavy metals from aqueous solution The experimental part of the paper was very detailed, including the reaction process of 1-Thiophen-2-yl-ethanone(cas: 88-15-3Electric Literature of C6H6OS)

1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Specialized thiophenes can be synthesized similarly using Lawesson’s reagent as the sulfidizing agent, or via the Gewald reaction, which involves the condensation of two esters in the presence of elemental sulfur. Another method is the Volhard–Erdmann cyclization. Electric Literature of C6H6OS

And the article was published in Journal of Organic Chemistry in 2019. Synthetic Route of C6H6OS The author mentioned the following in the article:

The chiral bisphosphine dioxide-catalyzed asym. conjugate reduction of acyclic β,β-disubstituted α,β-unsaturated ketones with trichlorosilane affords saturated ketones having a stereogenic carbon center at the carbonyl β-position with high enantioselectivities. Because the E/Z-isomerizations of enone substrates occur concomitantly, reduction products with the same absolute configurations are obtained from either (E)- or (Z)-enones. Conjugate reduction is accelerated in the presence of an electron-rich aryl group at the β-position of the enone owing to its carbocation-stabilizing ability. Computational studies were also conducted in order to elucidate the origin of the observed enantioselectivity. The regio- and enantioselective reductions of dienones were realized and applied to the syntheses of ar-turmerone, turmeronol A, mutisianthol, and jungianol, which are optically active sesquiterpenes.

《Assessment of headspace solid-phase microextraction (HS-SPME) for control of asymmetric bioreduction of ketones by Alternaria alternata》 was published in Biocatalysis and Biotransformation in 2020. These research results belong to Ogorek, Rafal; Jarosz, Bogdan. Synthetic Route of C6H6OS The article mentions the following:

The aim of this study was to assess the effectiveness of headspace solid-phase microextraction (HS-SPME) compared to liquid-liquid extractions using with methylene chloride (CH2Cl2) for control of fungal biotransformation of ketones of varying volatility. The proposed method was successfully applied. The best way to extract all the components of the mixture (alcs., aldehydes) in quantities similar to the extraction of methylene chloride was the use of fibers coated with a combination of nonpolar material. SPME fiber assembly polydimethylsiloxane/divinylbenzene (PDMS/DVB) was most suitable for the extraction of the products mixture obtained after biotransformation of acetylcyclohexane and acetophenone. On the other hand, the best results were obtained for 2-acetylthiophene, α,α,α-trifluoroacetophenone and their derivatives using divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) fiber. In addition, our study showed that Alternaria alternata is a good biocatalyst for bioreduction of ketones to alcs. according to Prelogs rule.

The microwave spectra of thiophene and 2-acetylthiophene were recorded in the frequency range from 2 to 40 GHz using two mol. jet Fourier transform microwave spectrometers. For 2-acetylthiophene, two conformers with a syn and an anti orientation of the S1-C2 and C6=O bonds (with respect to the C2-C6 bond) were identified, and the syn-conformer was more stable. The spectra of the 34S- and 13C-isotopologues of syn-2-acetylthiophene were also assigned, and the semiexperimental equilibrium structure could be determined Compared to thiophene, at the substitution position, the S1-C2 and C2C3 bond lengths both increase by about 0.007 Å, and the bond angle S1-C2C3 decreases by 0.06°, noticeably larger than the exptl. uncertainties. A-E torsional splittings were observed due to internal rotation of the Me group hindered by a barrier height of 330.187(35) and 295.957(17) cm-1 for the syn-conformer and the anti-conformer, resp. Geometry and internal rotation parameters are compared with those of related thiophene derivatives, as well as those of furan and 2-acetylthiophene to gain a better understanding of structure determination in the presence of Me internal rotation.

Thiophene and furan appended pyrazoline receptors R1 and R2 were designed and synthesized for selective detection of Al3+ ion. Their photophys. properties were studied by UV-visible and fluorescence spectra. Surprisingly, both receptors R1 and R2 were displayed an excellent selective and sensitive response to Al3+ ion alone over other tested metal ions. Both the receptor R1 and R2 displays 1:1 stoichiometry for [R1-Al3+] and [R2-Al3+] complex and formed with an association constant of 1.84 × 104 M-1 and 1.92 × 104 M-1 resp. The limit of detection were calculated for R1 and R2 since 8.92 × 10-8 M and 1.04 × 10-7 M by the fluorescence titration method. The thiophene based receptor R1 exhibited superior chemosensor characteristics such as high intensity absorption and emission at longer wavelength as compered that of furan based receptor R2.

Pyridine, one of the most important azaarenes, is ubiquitous in functional mols. The electronic properties of pyridine were exploited to trigger asym. transformations of prochiral species as a direct approach for accessing chiral pyridine derivatives However, the full potential of this synthetic strategy for the construction of enantioenriched γ-functionalized pyridines remains untapped. Here, the authors describe the first enantioselective addition of prochiral radicals to vinylpyridines under cooperative photoredox and asym. catalysis mediated by visible light. The enantioselective reductive couplings of vinylpyridines with aldehydes, ketones, and imines were achieved by employing a chiral Bronsted acid to activate the reaction partners and provide stereocontrol via H-bonding interactions. Valuable chiral γ-secondary/tertiary hydroxyl- and amino-substituted pyridines were obtained in high yields with good to excellent enantioselectivities.1-Thiophen-2-yl-ethanone(cas: 88-15-3Formula: C6H6OS) was used in this study.
