Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations

open access: yesAnnalen der Physik, EarlyView.
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

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 ...

A Bench‐Stable Fluorophosphine Nickel(0) Complex and Its Catalytic Application

open access: yesAngewandte Chemie, EarlyView.
We herein present the synthesis of a bench‐stable Ni(0) complex, [Ni(PFPh2)4], stabilized by vastly underexplored fluorophosphine ligands. The application of [Ni(PFPh2)4] in Suzuki–Miyaura and Kumada‐Tamao‐Corriu cross‐coupling reactions as well as in Buchwald–Hartwig C─N bond formation reactions, indicates its promising potential as alternative to ...

Asymmetric Coordination in Cobalt Single‐Atom Catalysts Enables Fast Charge Dynamics and Hierarchical Active Sites for Two‐Stage Kinetics in Photodegradation of Organic Pollutants

open access: yesAngewandte Chemie, EarlyView.
This investigation demonstrates an efficient synthetic methodology for the fabrication of atomically dispersed cobalt species anchored on carbon nitride substrate, featuring distinctive asymmetric Co─C2N3 coordination environments and hierarchical active sites.
