Kinetic Analysis of Transmetalation at Prototypical Nickel(II) Catalyst Species: Rates, Mechanisms, and Implications for Catalysis

Angewandte Chemie, EarlyView.
A 31P{1H} NMR method enabling direct measurement of transmetalation at Ni(II) is disclosed, providing an extensive kinetic dataset. Rates span five orders of magnitude and exhibit strong ligand dependence, with monodentate ligands promoting transmetalation.

Valency‐Controlled Multiphotochromism: Gated Switching and Photoswitchable Lewis Superacidity at Silicon

Angewandte Chemie, EarlyView.
Multiphotochromic switching is controlled by silicon valency in a diarylethene‐based molecular architecture. Lewis base coordination gates electronic communication between the photochromic units, thereby enabling selective access to distinct switching states.

Light‐Controlled Modulation of 15‐Lipoxygenase‐1 Regulates Intestinal Inflammatory Signaling

Angewandte Chemie, EarlyView.
The developed target‐guided strategy enables the rational design of diazo‐based photoswitchable inhibitors of 15‐lipoxygenase‐1. Distinct molecular architectures program opposite light‐dependent activity, allowing on‐demand control of enzyme inhibition.

Fundamental Understanding of Oxidative Stability in Fluorinated Asymmetric Ethers for Li Batteries

Angewandte Chemie, EarlyView.
To improve Li‐metal battery electrolytes, we analyze fluorinated 1‐ethoxy‐2‐methoxyethane (FxEME) oxidative stability via density functional theory (DFT) and molecular dynamics (MD). Fluorination strengthens ethoxy C–H bonds and alters solvent orientation at the cathode, weakening interfacial interactions.

Redirecting a Native Ene‐Reductase Toward Desaturation With Reverse Enantioselectivity

Angewandte Chemie, EarlyView.
A native ene‐reductase, XenA, was repurposed to catalyze the reverse‐enantioselective desaturation of cyclohexanones. The final variant was obtained through extensive protein engineering, combining PROSS‐guided computational design with mutagenesis and screening.

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

Angewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.
