Rate-Determining Step for Electrochemical Reduction of Carbon Dioxide into Carbon Monoxide at Silver Electrodes
Sophia Haussener, Etienne Boutin
Silver is one of the most studied electrode materials for the electrochemical reduction of carbon dioxide into carbon monoxide, a product with many industrial applications. There is a growing number of reports in which silver is implemented in gas diffusio ...
2024A Cobalt Nanocatalyst for the Hydrogenation and Oxidative Dehydrogenation of N-heterocycles
Paul Joseph Dyson, Mingyang Liu, Xiang Li, Yelin Hu, Matthias Beller
Catalytic hydrogenation and oxidative dehydrogenation of N-heterocycles to produce tetrahydroquinoline and quinoline derivatives are important reactions of particular importance in the agrochemical and pharmaceutical industries. Herein, we report earth-abu ...
Weinheim2023Head‐to‐Tail Dimerization of N‐Heterocyclic Diazoolefins
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Andrzej Sienkiewicz, Tak Hin Wong, Zhaowen Dong, Paul Varava, Anastasia Gitlina, Wolfram Feuerstein
The head-to-tail dimerization of N-heterocyclic diazoolefins is described. The products of these formal (3+3) cycloaddition reactions are strongly reducing quinoidal tetrazines. Oxidation of the tetrazines occurs in a stepwise fashion, and we were able to ...
2023Reactivity of Bromine Radical with Dissolved Organic Matter Moieties and Monochloramine: Effect on Bromate Formation during Ozonation
Bromine radical (Br center dot) has been hypothesized to be a key intermediate of bromate formation during ozonation. Once formed, Br center dot further reacts with ozone to eventually form bromate. However, this reaction competes with the reaction of Br c ...
AMER CHEMICAL SOC2023Who was afraid of Yuri Mikhailovich and why? (peculiarities of the reception of the Tartu version of structuralism after the 1960s)
The paper discussed different types of reactions to the emergence of Yuri Lotman's structuralism in the Soviet Union after 1960 ...
2023CO2 Capture and Release in Amine Solutions: To What Extent Can Molecular Simulations Help Understand the Trends?
Wanda Andreoni, Fabio Pietrucci, Changru Ma
Absorption in amine solutions is a well-established advanced technology for CO2 capture. However, the fundamental aspects of the chemical reactions occurring in solution still appear to be unclear. Our previous investigation of aqueous monoethanolamine (ME ...
MDPI2023Homogeneous catalysis with nitrous oxide
Nitrous oxide (N2O; ‘laughing gas’) is a powerful oxidant, but chemical transformations are hampered by the inert character of this gas. Recent advances in using N2O as an oxidant in metal-catalyzed reactions are discussed. The focus will be on reactions t ...
Elsevier2023Diverting the 5-exo-Trig Oxypalladation to Formally 6-endo-Trig Fluorocycloetherification Product through 1,2-O/Pd(IV) Dyotropic Rearrangement
Qian Wang, Jieping Zhu, Jing Gong
Pd-catalyzed cyclizative functionalization of γ-hydroxyalkenes affords tetrahydrofuran derivatives via a key 5-exo-trig oxypalladation step. Herein, we report a palladium(II)-catalyzed, Selectfluor-mediated formal 6-endo-trig fluorocycloetherification of γ ...
2023Photochemical [2+2] Cycloaddition of Alkynyl Boronates
Jérôme Waser, Oleksandr Liashuk
A photochemical [2+2] cycloaddition of alkynyl boronates and maleimides is reported. The developed protocol provided 35–70 % yield of maleimide-derived cyclobutenyl boronates and demonstrated wide compatibility with various functional groups. The synthetic ...
2023Migrative Carbofluorination of Saturated Amides Enabled by Pd-Based Dyotropic Rearrangement
Qian Wang, Jieping Zhu, Hua Wu, Simone Gallarati, Guoqiang Yang
Directly editing an all-carbon quaternary carbon itself of nonstrained acyclic molecules remains underexploited despite the recent advances in the fields of both C–H and C–C bond activation. Herein, we report a palladium-catalyzed migrative carbofluorinati ...
