Radical‐Polar Crossover Bicyclization Enables a Modular Synthesis of Saturated Bicyclic Amines

Advanced Science, EarlyView.
Herein, we report the successful realization of a radical‐polar crossover bicyclization reaction from easily available cyclopropylamines and substituted alkenes through photoredox catalysis. This approach introduces an innovative methodology for the de novo synthesis of a diverse collection of 4/5‐, 5/5‐, 6/5‐,7/5‐ and 5/6‐fused saturated bicyclic ...

Sinter‐ and Water‐Resistant Pt Enabled by High Entropy of Porous Oxide Nanofibers

Advanced Science, EarlyView.
The high‐entropy effect thermodynamically favors a unique distribution of multiple constituent elements within the crystalline lattice with low Gibbs free energy. This special configuration endows the material with exceptional stability, depressing the growth of Pt species at elevated temperatures.

In Situ Converting Conformal Sacrificial Layer Into Robust Interphase Stabilizes Fluorinated Polyanionic Cathodes for Aqueous Sodium‐Ion Storage

Advanced Science, EarlyView.
A unique interfacial conversion concept is proposed to establish robust cathode electrolyte interphase for stabilizing fluorinated polyanionic cathodes in aqueous electrolytes. In a typical case, the conformal Al2O3 sacrificial layer is predeposited on high‐voltage sodium vanadium oxy‐fluorophosphates cathode, which can progressively react with trace ...

Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...
