Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

open access: yesAngewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Coordinating Mesopore Geometry and Interfacial Water Dynamics for Iron‐Site Evolution in Nitrate Electroreduction

open access: yesAngewandte Chemie, EarlyView.
Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

open access: yesAngewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐
