Light‐Induced Dispersion of Pd Single Atoms Provides Steady‐State‐Stabilized Activity for Photocatalytic H2 Generation

Angewandte Chemie, EarlyView.
High photon flux causes (re)distionpersion of atomic Pd species on TiO2 in photocatalytic experiments, whereas Pt SAs undergo continuous agglormation. This allows light‐driven stabilization of active Pd centers for sustained H2 evolution. ABSTRACT In recent years, the use of single atoms (SAs) has become increasingly significant in photocatalysis ...

Kinetic, Spectroscopic, and X-Ray Crystallographic Evidence for the Cooperative Mechanism of the Hydration of Nitriles Catalyzed by a Tetranuclear Ruthenium-μ-oxo-μ-hydroxo Complex [PDF]

, 2008
The tetranuclear ruthenium-oxo-hydroxo-hydride complex {[(PCy3)(CO)RuH]4(μ4-O)(μ3-OH)(μ2-OH)} (1) was found to be a highly cooperative catalyst for the nitrile hydration reaction. The cooperative mechanism of the hydration of benzonitrile was established

Influence of Hydrogen‐Incorporation on the Bulk Electronic Structure and Chemical Bonding in Palladium

Advanced Science
Palladium hydride is a model system for studying metal‐hydrogen interactions. Yet, its bulk electronic structure has proven difficult to directly probe, with most studies to date limited to surface‐sensitive photoelectron spectroscopy approaches.

Mimicking a Light‐Harvesting Complex to Accelerate Photooxidation in Asymmetric Lipid Membrane Nanoreactors

Angewandte Chemie International Edition, EarlyView.
Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...

Isolation and Reactivity of a Square‐Planar Trisamido Silane

Angewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

A Synergistic Inhibitor Development Strategy Against Human UDP‐Galactose‐4‐Epimerase

Angewandte Chemie International Edition, EarlyView.
The epimerase GalE is crucial for the biosynthesis of cancer‐relevant O‐GalNAc glycans. Here, we employ orthogonal, structurally enabled small molecule fragment screens to yield both covalent and non‐covalent inhibitors against GalE within no more than 22 elaborated compounds.
