Traces of Elements in the Electrochemical Reductive Amination of Acetone: Uncovering Bi as Substitute for Pb

Angewandte Chemie International Edition, EarlyView.
This study investigates the impact of various p‐block element impurities in the electrochemical reductive amination and reveals with Bi a less toxic alternative for Pb. The utilization of Bi as additive was further optimized by studying the impact of additive concentration, reaction temperature, and cathode material on amine yield, offering new ...

High‐Temperature Superconductivity in Perovskite Hydride Below 10 GPa

Advanced Science
Hydrogen and hydride materials have long been considered promising materials for high‐temperature superconductivity. However, the extreme pressures required for the metallization of hydrogen‐based superconductors limit their applications.

Molecular Mimics of Intermetallic Phases: Selective Alkylamide‐Ligand Deprotection Drives Co/Ga Cluster Formation

Angewandte Chemie International Edition, EarlyView.
The bimetallic M14 cluster [Co3Ga2]H(μ2‐GaTMP)9 was achieved by a co‐reductive approach utilizing Mg and H2 to selectively deprotect and capture the Ga‐TMP metallo‐ligands, forming a Co/Ga alloyed cluster kernel, making it a structural representative of a related solid‐state counterpart.

Hydrogen Activation via Dihydride Formation on a Rh1/Fe3O4(001) Single‐Atom Catalyst

Angewandte Chemie International Edition, EarlyView.
Deuterium (hydrogen) adsorption on single‐atom Rh1/Fe3O4(001) catalyst does not induce D (H) spillover onto the reducible Fe3O4 support. Instead, a Rh1‐dihydride (Rh−2D or Rh−2H) species forms and D2 or H2desorbs during annealing. ABSTRACT Hydrogen activation is a key elementary step in catalytic hydrogenation.

Data-driven design of high pressure hydride superconductors using DFT and deep learning

Materials Futures
The observation of superconductivity in hydride-based materials under ultrahigh pressures (for example, H _3 S and LaH _10 ) has fueled the interest in a more data-driven approach to discovering new high-pressure hydride superconductors. In this work, we

Theoretical Study on the Dynamical Stability, Chemical Bonding, and Electronic Properties of LaBH8 and LaBeH8 Under Pressure

Advanced Physics Research
LaBH8 and LaBeH8, as typical Fm‐3m XYH8‐type hydrides, are predicted with outstanding superconductivity below megabar pressure. Notably, LaBeH8 has been successfully synthesized with the predicted XYH8‐type structure and measured to have a critical ...

Aluminum versus Gallium: Differences in Bis(bis(trimethylsilyl)methyl) Element Halides, Hydrides, and Oxygen‐Bridged E/P Frustrated Lewis Pairs

ChemistryEurope
Extremely sterically demanding bis(bis(trimethylsilyl)methyl)‐substituted aluminum and gallium compounds are particularly suitable for applications in frustrated Lewis pair (FLP) chemistry. A selective exchange reaction between Bis2GaBr (Bis = CH(SiMe3)2)
