Compressed hydrides as metallic hydrogen superconductors

Physical review B, 2019
The 2014-2015 prediction, discovery, and confirmation of record high temperature superconductivity above 200K in H$_3$S, followed by the 2018 extension to superconductivity in the 250-280K range in lanthanum hydride, marks a new era in the longstanding ...

Isolation und Reaktivtät eines quadratisch‐planaren Trisamidosilans

Angewandte Chemie, EarlyView.
Wir berichten über die Synthese und umfassende Charakterisierung eines quadratisch‐planaren Si(+IV)‐Hydrids, das von einem unsymmetrischen, trianionischen und dearomatisierten N,N,N‐Pincerliganden stabilisiert wird. Dieses System ermöglicht eine Element–Liganden‐kooperative Reaktivität als Alternative zur siliciumzentrierten Redoxchemie und erweitert ...

Cobalt‐Catalyzed Intramolecular C─H Silylation of Arenes

Angewandte Chemie, EarlyView.
Direct C─Si bond formation via C─H silylation is an atom‐economical route to organosilanes but is largely limited to noble metals. We report the first cobalt‐catalyzed intramolecular arene C–H silylation enabled by HCo(PMe3)4, which activates Si–H and C–H bonds to form diverse silacycles and silafluorenes in high yields with broad functional‐group ...

Synergistische Entwicklungsstrategien von Inhibitoren gegen humane UDP‐Galactose‐4‐Epimerase

Angewandte Chemie, EarlyView.
Die Epimerase GalE ist essenziell für die Biosynthese von krebsrelevanten O‐GalNAc Glykanen. Wir verwenden orthogonales, strukturbasiertes Screening niedermolekularer Fragmente an, um kovalente und nichtkovalente Inhibitoren gegen GalE mit nicht mehr als 22 optimierten Verbindungen zu erhalten.

Radikale Kaskadenreaktion, welche die Kreuzkupplung von Olefinen mit der Smiles‐Truce‐Umlagerung kombiniert

Angewandte Chemie, EarlyView.
Wir stellen eine kobaltkatalysierte Radikalkaskade vor, die zwei Alken Ausgangsstoffe effizient miteinander verbindet und so in einem einzigen Schritt mehrere Bindungen aufbaut. Der Prozess beginnt mit einem kobaltkatalysierten Wasserstoffatomtransfer an eine Styrol‐Doppelbindung, gefolgt von einer Giese‐Addition.

Alcohol‐Directed Carboamination of Conjugated Enynes

Angewandte Chemie, EarlyView.
The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.

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 ...

Effect of Heating Rate on Hydride Reorientation Behavior of Zirconium Alloy Tubes under Non-Stress Loading

Metals
Zirconium alloys are widely used in nuclear water reactors as cladding materials. The cladding materials will absorb hydrogen from high temperature water during the operation of nuclear reactor.
