Jurd, Peter M.’s team published research in Organometallics in 2020 | CAS: 623-47-2

Ethyl propiolate(cas: 623-47-2) is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.COA of Formula: C5H6O2

《The Reaction of Iron Acetylides with Carbon Dioxide》 was written by Jurd, Peter M.; Li, Hsiu L.; Bhadbhade, Mohan; Dalgarno, Scott J.; McIntosh, Ruaraidh D.; Field, Leslie D.. COA of Formula: C5H6O2 And the article was included in Organometallics in 2020. The article conveys some information:

The acetylido Fe hydride trans-[FeH(CCH)(depe)2] reacts with an excess of CO2 at ambient pressure and temperature to form a five-membered metalalactone cis-[Fe(OC(O)CHCH-κ2C,O)(depe)2]. The reaction appears to proceed by electrophilic addition of CO2 to the β-C of the coordinated acetylide and cyclization to form the metalalactone product. At low temperature, a 2nd mol. of CO2 is incorporated to give a carboxy-substituted metalalactone cis-[Fe(OC(O)C(C(O)OH)CH-κ2C,O)(depe)2]. When the initial metal acetylido hydride is substituted at the β-acetylenic C, the addition of CO2 results in a metalalactone where the substituent is in the position adjacent to the carbonyl in the metalalactone ring. In the experimental materials used by the author, we found Ethyl propiolate(cas: 623-47-2COA of Formula: C5H6O2)

Ivanov, Svetlozar’s team published research in ChemPhysChem in 2019 | CAS: 872-36-6

The author of 《Microgravimetric and Spectroscopic Analysis of Solid-Electrolyte Interphase Formation in Presence of Additives》 were Ivanov, Svetlozar; Mai, Sebastian; Himmerlich, Marcel; Dimitrova, Anna; Krischok, Stefan; Bund, Andreas. And the article was published in ChemPhysChem in 2019. HPLC of Formula: 872-36-6 The author mentioned the following in the article:

Electrochem. quartz crystal microbalance (EQCM) with damping monitoring is applied for real-time anal. of solid-electrolyte interphase (SEI) formation in di-Ph octyl phosphate (DPOP) and vinylene carbonate (VC) modified electrolytes. Fast SEI formation is observed for the DPOP containing electrolyte, whereas slow growth is detected in VC-modified and reference electrolytes. QCM measurements in a dry state show considerable reduction of the mass quantity for DPOP and reference samples and minor mass decrease for the SEI layer formed in the presence of VC. VC enhances SEI stability, whereas the addition of DPOP or no additive results in incorporation of loosely attached species, leading to SEI instability. Resonance frequency damping, Δw, and dissipation factor, D, were used for analyzing mech. properties of the SEI layers. The apparent increase of Δw and D during SEI formation in presence of DPOP suggests a pronounced viscoelasticity of the layer. QCM results are compared with surface morphol. and chem. composition, revealing excellent agreement of the applied characterization approaches. In the experimental materials used by the author, we found Vinylene carbonate(cas: 872-36-6HPLC of Formula: 872-36-6)

Sun, Xi-Shang’s team published research in Chemical Science in 2022 | CAS: 623-47-2

In 2022,Sun, Xi-Shang; Diao, Xin-Yu; Dong, Xiu-Qin; Wang, Chun-Jiang published an article in Chemical Science. The title of the article was 《Base-promoted cascade β-F-elimination/electrocyclization/Diels-Alder/retro-Diels-Alder reaction: efficient access to δ-carboline derivatives》.Product Details of 623-47-2 The author mentioned the following in the article:

A serendipitous and highly efficient approach for the construction of a variety of δ-carboline derivatives was developed through base-promoted cascade β-F-elimination/electrocyclization/Diels-Alder/retro-Diels-Alder reaction of N-2,2,2-trifluoroethylisatin ketoimine esters with alkynes in good to high yields with excellent regio-/chemoselectivity control. Moreover, a reasonable reaction pathway was proposed, which was in accordance with the prepared reaction intermediate and control experiment results. The δ-carboline product could be easily converted into a new chiral Py-box-type ligand through simple synthetic transformations. This salient strategy featured the advantages of metal-free conditions, excellent regio-/chemoselectivity, good to high yields, and outstanding substrate tolerance. Importantly, the potential application of these fascinating δ-carboline derivative products is well demonstrated in the recognition of ferric ions. In the experiment, the researchers used many compounds, for example, Ethyl propiolate(cas: 623-47-2Product Details of 623-47-2)

Yan, Liping’s team published research in Dalton Transactions in 2021 | CAS: 623-47-2

Yan, Liping; Yan, Chenting; Xu, Jian; Yang, Lele; Bian, Gaofeng; Wang, Liliang; Kira, Mitsuo; Li, Zhifang published an article in 2021. The article was titled 《Diverse reactions of a fluorostannylenoid towards ethynes》, and you may find the article in Dalton Transactions.Application of 623-47-2 The information in the text is summarized as follows:

Fluoro(dialkyl)stannylenoid 2 exhibits unique reactivity towards ethynes with acetylenic H and those with trimethylsilyl groups, though the corresponding free dialkylstannylene 1 is inactive against those ethynes. Stannylenoid 2 reacts smoothly with gaseous ethyne and phenylethyne at room temperature, giving the corresponding diethynylstannanes, di(phenylethynyl)stannane 3 and diethynylstannane 6, resp., in good yields with the concomitant evolution of H2. Trimethylsilyl-substituted ethynes such as 1-trimethylsilyl-(2-phenyl)ethyne and 1,2-bis(trimethylsilyl)ethyne react similarly to give 3 and bis(trimethylsilylethynyl)stannane 8, resp. Rather unexpectedly, the reaction of 2 with (trimethylsilyl)ethyne affords 1,2-bis(ethenylstannyl)ethyne 7 in a good yield. The reactions of 2 with Me and Et propynoates give the same products 4 and 5 as those obtained during the reaction of dialkylstannylene 1 without CsF. Pathways involving the nucleophilic attack of Cs acetylide to an ethyne-complexed stannylene are proposed, while the detailed mechanisms remain unknown. The structure of 7 was studied by single crystal x-ray diffraction anal. In the experimental materials used by the author, we found Ethyl propiolate(cas: 623-47-2Application of 623-47-2)

Li, Wangda’s team published research in Chemistry of Materials in 2020 | CAS: 872-36-6

《Long-Term Cyclability of NCM-811 at High Voltages in Lithium-Ion Batteries: an In-Depth Diagnostic Study》 was written by Li, Wangda; Liu, Xiaoming; Xie, Qiang; You, Ya; Chi, Miaofang; Manthiram, Arumugam. Application of 872-36-6 And the article was included in Chemistry of Materials in 2020. The article conveys some information:

High-nickel layered oxides, such as LiNi0.8Co0.1Mn0.1O2 (NCM-811), offer higher energy d. than their low-nickel counterparts at a given voltage and are gaining major traction in automotive lithium-ion batteries for elec. vehicles. Besides high-Ni content, higher charging voltages above 4.3 V vs Li+/Li boost the energy and represent another focus in battery development. Here, we investigate the long-term cyclability of NCM-811 in graphite pouch cells over 1000 deep cycles between 2.5-4.2, 2.5-4.4, and 2.5-4.5 V through a suite of sensitive characterization techniques. The NCM-811 full cells show severely deteriorated cyclability with higher charging voltages, from 78% at 4.2 V to 52 and 32% at 4.4 and 4.5 V, resp. At 4.2 V, minor parasitic electrolyte oxidation as well as cathode Li/Ni mixing and cracking are revealed after cycling, while transition-metal dissolution and surface reconstruction into rock-salt NiO are virtually undetectable. At 4.4 and 4.5 V, transition-metal dissolution and crossover to the anode become much more pronounced and a primary contributor to the capacity fade, while significant surface NiO formation causes substantial voltage polarization, which is less noticeable at 4.2 V. Meanwhile, more severe electrolyte oxidation, Li/Ni mixing, and particle pulverization exacerbate the voltage and capacity fade. These results outline distinct challenges for stable high-Ni layered oxide cathodes in high-voltage Li-ion batteries. The experimental process involved the reaction of Vinylene carbonate(cas: 872-36-6Application of 872-36-6)
