Breaking the Activity‐Stability Trade‐Off of RuO2 via Metallic Ru Bilateral Regulation for Acidic Oxygen Evolution Reaction

open access: yesAngewandte Chemie, EarlyView.
RuO2 electrocatalysts, which followed a kinetically favorable lattice oxygen mechanism, perform a preferable intrinsic activity, but poor stability for acidic oxygen evolution. This work offer a strategy which introduce metallic Ru onto RuO2 to build the Ru4+─O─Ru0 interfacial structure for decreasing the Ru4+ oxidation state and promoting ...

Efficient Nickel Precatalysts for Suzuki‐Miyaura Cross‐Coupling of Aryl Chlorides and Arylboronic Acids Under Mild Conditions

open access: yesAngewandte Chemie, EarlyView.
The synthesis and catalytic properties of Ni(II) complexes, with the general formula Ni(NHC)[P(OR)3](Ar)Cl, are described. These air‐stable complexes are effective under mild conditions and low catalytic loading for the Suzuki‐Miyaura cross‐coupling for a range of electronically and sterically differentiated coupling partners.

H2S Sensing with SnO2‐Based Gas Sensors: Sulfur Poisoning Mechanism Revealed by Operando DRIFTS and DFT Calculations

open access: yesAngewandte Chemie, EarlyView.
The formation of sticky sulfite and sulfate surface species is identified as the root cause of the poisoning effect of H2S on SnO2‐based sensors by the compelling results and detailed analyses from operando DRIFTS experiments and density functional theory (DFT) calculations.

Site‐Selective Carbonylation of Azetidines via Copper‐Catalyzed Difluorocarbene Insertion

open access: yesAngewandte Chemie, EarlyView.
We disclose a site‐selective Cu‐catalyzed carbonylation of azetidines promoted by difluorocarbene insertion at low temperature, enabling access to a variety of functionalized γ‐lactams and a therapeutic agent for diabetes (40 examples). This skeletal expansion strategy provides a distinct disconnection approach to synthesize medicinally relevant five ...
