Wu, Wen-Biao’s team published research in Journal of Organic Chemistry in 2020 | CAS: 88-15-3

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. Quality Control of 1-Thiophen-2-yl-ethanone

《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)
