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.

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.

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries

Angewandte Chemie, EarlyView.
This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Slowing Down Water: Enhanced and Cation‐responsive MRI Contrast

Angewandte Chemie, EarlyView.
The controlled modification of mesoporous silica nanoparticle side walls with kosmotropic motifs supports an ability to reduce water diffusive mobility and dramatically increase MRI contrast to levels unprecedented for highly kinetically stable Gd‐DOTA configurations (both q = 1 and q = 0).

Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

Angewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...
