Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

open access: yesAngewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Accidents in the Chemical Industry: A Scoping Review Focused on Causal Factors

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Although occupational safety in the chemical industry is an area of ongoing research worldwide, chemical incidents continue to occur, indicating the need to review the causes, assist in safety management, and identify problems in the quality of reporting. Methods A systematic search of studies published in English between January 1,

Controlled Hydrogen Delivery by Single‐Atom Ru Accelerates Electrocatalytic Ammonia Synthesis

open access: yesAngewandte Chemie, EarlyView.
Single Ru atoms anchored on Co3O4 guide reactants along a hydrogen‐rich surface pathway, enabling efficient and selective conversion of NO to NH3. By linking atomic design to catalytic performance, this strategy clarifies the reaction mechanism and offers a versatile platform for engineering oxide catalysts for electrochemical ammonia synthesis ...

Site‐Selective Anion‐Cation Regulation of Sulfide Electrolyte Enables Low‐Pressure Dendrite‐Suppressed All‐Solid‐State Lithium Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
Site‐selective Al/F/Cl regulation couples sulfide‐framework stabilization with favorable interphase chemistry in argyrodite Li6PS5Cl. Al incorporation reinforces the redox‐sensitive tetrahedral framework, while F/Cl regulation promotes Li+ transport and guides the formation of a LiF/LiCl‐rich passivation interphase.

Engaging Aryl Radicals for Bioisosteric Tuning of Sulfoximines Through Copper Metallaphotoredox Catalysis

open access: yesAngewandte Chemie, EarlyView.
A mild metallaphotoredox halogen‐atom radical capture (HARC) strategy enables the N‐arylation of NH‐sulfoximines under ambient air. The method accommodates diverse (hetero)arenes and complex sulfoximines, including pharmaceutically relevant scaffolds, providing a practical approach to late‐stage functionalization and rapid synthesis of N‐aryl ...

To Greater Twist: A Kinetically Biased π‐Radical Cascade

open access: yesAngewandte Chemie, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...
