Ambient Hydrocarbonylation of Olefins Enabled by Visible‐Light

open access: yesAdvanced Science, EarlyView.
A novel photo‐induced methodology for hydrocarbonylation has been established, resolving the inherent conflicts between competitive olefin and CO insertion in traditional methods that necessitate harsh conditions. Accordingly, an efficient and versatile hydrocarbonylation of olefins enabled by visible‐light irradiation under ambient conditions has been

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

open access: yesAngewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.
