The article was titled 《Radical Addition Enables 1,2-Aryl Migration from a Vinyl-Substituted All-Carbon Quaternary Center》, and you may find the article in Angewandte Chemie, International Edition.Electric Literature of C4H6BrFO2 The information in the text is summarized as follows:

An efficient method for photocatalytic perfluoroalkylation of vinyl-substituted all-carbon quaternary centers involving 1,2-aryl migration was developed. The rearrangement reactions use fac-Ir(ppy)3, visible light and com. available fluoroalkyl halides and can generate valuable multisubstituted perfluoroalkylated compounds in a single step that would be challenging to prepare by other methods. Mechanistically, the photoinduced alkyl radical addition to an alkene leads to the migration of a vicinal aryl substituent from its adjacent all-carbon quaternary center with the concomitant generation of a C-radical bearing two electron-withdrawing groups that is further reduced by a hydrogen donor to complete the domino sequence. In the experiment, the researchers used Ethylbromofluoroacetate(cas: 401-55-8Electric Literature of C4H6BrFO2)

Computed Properties of C4H6BrFO2On May 16, 2022 ,《Biocatalytic Asymmetric Construction of Secondary and Tertiary Fluorides from β-Fluoro-α-Ketoacids》 appeared in Angewandte Chemie, International Edition. The author of the article were Fang, Jason; Turner, Laura E.; Chang, Michelle C. Y.. The article conveys some information:

Fluorine is a critical element for the design of bioactive compounds, driving advances in selective and sustainable fluorination. However, stereogenic tertiary fluorides pose a synthetic challenge and are thus present in only a few approved drugs (fluticasone, solithromycin, and sofosbuvir). The aldol reaction of fluorinated donors provides an atom-economical approach to asym. C-F motifs via C-C bond formation. Authors report that the type II pyruvate aldolase HpcH and engineered variants perform addition of β-fluoro-α-ketoacids (including fluoropyruvate, β-fluoro-α-ketobutyrate, and β-fluoro-α-ketovalerate) to diverse aldehydes. The reactivity of HpcH towards these fluoro-donors grants access to enantiopure secondary or tertiary fluorides. In addition to representing the first synthesis of tertiary fluorides via biocatalytic carboligation, the afforded products could improve the diversity of fluorinated building blocks and enable the synthesis of fluorinated drug analogs.

《An Olefinic 1,2-Boryl-Migration Enabled by Radical Addition: Construction of gem-Bis(boryl)alkanes》 was published in Angewandte Chemie, International Edition in 2019. These research results belong to Zhao, Binlin; Li, Zexian; Wu, Yixiao; Wang, Yandong; Qian, Jiasheng; Yuan, Yu; Shi, Zhuangzhi. Product Details of 401-55-8 The article mentions the following:

A series of in situ formed alkenyl diboronate complexes from alkenyl Grignard reagents (com. available or prepared from alkenyl bromides and Mg) with B2Pin2 (bis(pinacolato)diboron) react with diverse alkyl halides by a Ru photocatalyst to give various gem-bis(boryl)alkanes. Alkyl radicals add efficiently to the alkenyl diboronate complexes, and the adduct radical anions undergo radical-polar crossover, specifically, a 1,2-boryl-anion shift from boron to the α-carbon sp2 center. This transformation shows good functional-group compatibility and can serve as a powerful synthetic tool for late-stage functionalization in complex compounds Measurements of the quantum yield reveal that a radical-chain mechanism is operative in which the alkenyl diboronates acts as reductive quencher for the excited state of the photocatalyst.

《A Copper(I)-Catalyzed Radical-Relay Reaction Enabling the Intermolecular 1,2-Alkylborylation of Unactivated Olefins》 was written by Akiyama, Sota; Oyama, Natsuki; Endo, Tsubura; Kubota, Koji; Ito, Hajime. Name: Ethylbromofluoroacetate And the article was included in Journal of the American Chemical Society on April 7 ,2021. The article conveys some information:

The 1st catalytic intermol. 1,2-alkylborylation reaction via a radical-relay mechanism between unactivated olefins, bis(pinacolato)diboron, and an alkyl electrophile is reported. Successful implementation of this method requires that the competing boryl substitution of the alkyl electrophile is retarded to facilitate the radical relay. This challenge was overcome using electronically or sterically demanding alkyl electrophiles, which results in the simultaneous and highly regioselective introduction of a gem-difluoro, monofluoro, tertiary, or secondary alkyl group and a boryl group across the C:C double bond.Ethylbromofluoroacetate(cas: 401-55-8Name: Ethylbromofluoroacetate) was used in this study.

Multicomponent reactions are fundamentally different from two-component reactions, as multicomponent reactions can enable the efficient and step-economical construction of complex mol. scaffolds from simple precursors. Here, an unprecedented three-component direct C-H addition was achieved in the challenging meta-selective fashion. Fluoroalkyl halides and a wide range of alkenes, including vinylarenes, unactivated alkenes, and internal alkenes, were employed as the coupling partners of arenes in this strategy. The detailed mechanism presented is supported by kinetic isotope studies, radical clock experiments, and d. functional theory calculations Moreover, this strategy provided access to various fluoride-containing bioactive 1,1-diarylalkanes and other challenging synthetically potential products.

The article conveys some information:

Multidrug resistant Gram-neg. bacterial infections are an increasing public health threat due to rapidly rising resistance toward β-lactam antibiotics. The hydrolytic enzymes called β-lactamases are responsible for a large proportion of the resistance phenotype. β-Lactamase inhibitors (BLIs) can be administered in combination with β-lactam antibiotics to negate the action of the β-lactamases, thereby restoring activity of the β-lactam. Newly developed BLIs offer some advantage over older BLIs in terms of enzymic spectrum but are limited to the i.v. route of administration. Reported here is a novel, orally bioavailable diazabicyclooctane (DBO) β-lactamase inhibitor. This new DBO, ETX1317(I), contains an endocyclic carbon-carbon double bond and a fluoroacetate activating group and exhibits broad spectrum activity against class A, C, and D serine β-lactamases. The ester prodrug of ETX1317, ETX0282(II), is orally bioavailable and, in combination with cefpodoxime proxetil, is currently in development as an oral therapy for multidrug resistant and carbapenem-resistant Enterobacterales infections.
