Visible light mediated facile and selective dithiane deprotection under metal free conditions is developed. Eosin Y (1 mol%) proved to be an effective catalyst for the dithiane deprotection under the ambient photoredox conditions. The standard household compact fluorescent light source (CFL bulb) proved to be effective under open-air conditions in aqueous acetonitrile at room temperature The protocol that exhibits a broad substrate scope and functional group tolerance has been shown to expand to a range of transformations for the electron-rich and -deficient thioacetals and thioketals. The synthetic utility of this protocol has also been demonstrated by gram-scale application.

1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Reflecting their high stabilities, thiophenes arise from many reactions involving sulfur sources and hydrocarbons, especially unsaturated ones. Thiophenes are classically prepared by the reaction of 1,4-diketones, diesters, or dicarboxylates with sulfidizing reagents such as P4S10 such as in the Paal-Knorr thiophene synthesis.

Su, Biyun; Han, Qiaoqiao; Li, Xiaoteng; Hou, Yifan; Wu, Jindi; Wang, Li; Ding, Liqin published an article in 2021. The article was titled 《Synthesis, isomerization, and DFT studies of five-membered heterocyclic ketoximes》, and you may find the article in Journal of Chemical Research.Synthetic Route of C6H6OS The information in the text is summarized as follows:

A homologous series of five-membered heterocyclic ketoximes was synthesized by condensation reactions of 2-acetylpyrrole, 2-acetylthiophene, and 2-acetylfuran with hydroxylamine hydrochloride. These compounds were fully characterized by X-ray single-crystal diffraction, elemental anal., 1H NMR, IR, UV-Vis, and fluorescence spectra. Interesting isomerization phenomena are observed for these heterocyclic ketoximes by different characterization methods. By means of 1H NMR and X-ray single-crystal diffraction, it was found that 2-acetylpyrrole oxime exists as the Z-type geometric isomer, 2-acetylfuran oxime exists as the E-isomer, while 2-acetylthiophene oxime was identified as a mixture of Z- and E-isomers. To study the above phenomena further, quantum chem. calculations of total energy, dipole moment, EHOMO, ELUMO, and other parameters of each heterocyclic ketoxime were carried out by D. functional theory (DFT). The theor. calculations were in good accordance with the exptl. spectroscopic results. After reading the article, we found that the author used 1-Thiophen-2-yl-ethanone(cas: 88-15-3Synthetic Route of C6H6OS)

《Carbonyl-Stabilized Phosphorus Ylide as an Organocatalyst for Cyanosilylation Reactions Using TMSCN》 was published in Journal of Organic Chemistry in 2020. These research results belong to Wu, Wen-Biao; Zeng, Xing-Ping; Zhou, Jian. Quality Control of 1-Thiophen-2-yl-ethanone The article mentions the following:

The authors report carbonyl-stabilized P ylides as general and efficient catalysts for the cyanosilylation of ketones. The N,N-diethylacetamide derived phosphorane is identified as an extremely efficient catalyst for the cyanosilylation of dialkyl ketones, alkyl aryl ketones, diaryl ketones, and α,β-unsaturated enones with catalyst loading down to 0.005 mol %, the lowest ever known for ketone cyanosilylation. Aldehydes, aldimines, and ketimines are also viable substrates. By NMR and React IR anal., as well as elec. conductivity experiments, probably the phosphorane acts as a Lewis base to mediate the reaction via the desilylative nucleophilic activation of TMSCN. In the part of experimental materials, we found many familiar compounds, such as 1-Thiophen-2-yl-ethanone(cas: 88-15-3Quality Control of 1-Thiophen-2-yl-ethanone)

The article was titled 《Direct synthesis of ring-fused quinolines and pyridines catalyzed by NNHY-ligated manganese complexes (Y = NR2 or SR)》.HPLC of Formula: 88-15-3 The article contains the following contents:

Four cationic manganese(I) complexes, [(fac-NNHN)Mn(CO)3]Br (Mn-1-Mn-3) and [(fac-NNHS)Mn(CO)3]Br (Mn-4) (where NNH is a 5,6,7,8-tetrahydro-8-quinolinamine moiety), have been synthesized and evaluated as catalysts for the direct synthesis of quinolines and pyridines by the reaction of a γ-amino alc. with a ketone or secondary alc.; NNHS-ligated Mn-4 proved the most effective of the four catalysts. The reactions proceeded well in the presence of catalyst loadings in the range 0.5-5.0 mol% and tolerated diverse functional groups such as alkyl, cycloalkyl, alkoxy, chloride and hetero-aryl. A mechanism involving acceptorless dehydrogenation coupling (ADC) has been proposed on the basis of DFT calculations and exptl. evidence. Significantly, this manganese-based catalytic protocol provides a promising green and environmentally friendly route to a wide range of synthetically important substituted monocyclic, bicyclic as well as tricyclic N-heterocycles (including 50 quinoline and 26 pyridine examples) with isolated yields of up to 93%.

The aim of this study was to investigate the formation of furan and acrylamide and to compare antioxidant capacities and volatile compounds in cold or hot brewed coffees. Cold brews were prepared at 5°C and 20°C for 12 h. using steeping and dripping, and hot brews were prepared at 80°C and 95°C for 5 min. using the pour-over method. Furan contents of cold steeping at 5°C and hot brewed at 80°C showed the higher levels significantly (p < 0.05), which were 17.0 ± 0.5 and 10.6 ± 0.1 ng/mL, resp. However, acrylamide contents in cold steeping at 5°C and hot brew at 80°C showed lower levels, which were 4.1 ± 0.4 and 3.5 ± 0.1 ng/mL resp. Cold brews at 20°C showed the highest levels of antioxidant activities while hot brews showed similar levels with cold brews at 5°C. This study confirms that levels of different beneficial and hazardous chem. compounds could be manipulated by adjusting the coffee extraction conditions.

《Enhanced Two-Photon Absorption of Cross-Conjugated Chalcone Derivatives: Modulation of the Effective π-Conjugated Structure》 was written by Jia, Jidong; Zhang, Xueru; Wang, Yuxiao; Shi, Yufang; Sun, Jinyu; Yang, Junyi; Song, Yinglin. Formula: C6H6OS And the article was included in Journal of Physical Chemistry A in 2020. The article conveys some information:

Three cross-conjugated chalcone derivatives T3CT, T3CP2, and T3CP3 were designed and synthesized to develop excellent organic nonlinear optical (NLO) materials. In a Z-scan experiment, all compounds show good NLO absorption characteristics in the visible to near-IR region. The photophys. mechanism is confirmed to be two-photon absorption (TPA)-induced excited-state absorption (ESA). Intramol. charge transfer (ICT) observed in transient absorption spectra (TAS) significantly affects mol. NLO properties. We define the π-conjugated system that dominates the electron transition process in the cross-conjugated structure as the effective π-conjugated structure. Electron transition anal. shows a sufficiently strong ICT can effectively expand the effective π-conjugated structure in these cross-conjugated structures. The TPA cross sections of these compounds at 650 and 750 nm are only in the range of 17-97 GM. However, we achieve a significant enhancement of the TPA cross section at 580 nm (1737-2027 GM) by extending the effective π-conjugated structure. Excited by 580 nm femtosecond laser pulses, all compounds exhibit excellent OL performance and the min. OL threshold is 4.71 x 10-3 J/cm2. The results show that these cross-conjugated chalcone derivatives have promising applications in OL, and their NLO performance can be effectively improved by modulating the effective π-conjugated structure. The results came from multiple reactions, including the reaction of 1-Thiophen-2-yl-ethanone(cas: 88-15-3Formula: C6H6OS)
