Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement

open access: yesAngewandte Chemie International Edition, EarlyView.
We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.

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

open access: yesMaterials 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

open access: yesAdvanced 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

open access: yesChemistryEurope
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)

Geminal Difunctionalization of Ketones via C─S Bond Insertion of Photogenerated Donor–Donor Diazo Compounds

open access: yesAngewandte Chemie International Edition, EarlyView.
Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

open access: yesAngewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Engineering of CoA‐Acylating Butyraldehyde Dehydrogenase for Enhanced 1,3‐Butanediol Production in Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Microbial production of 1,3‐butanediol (1,3‐BDO) offers a renewable route to this versatile C4 chemical. However, the low performance of CoA‐acylating butyraldehyde dehydrogenase (Bld), which contains a catalytic cysteine, limits efficient production in recombinant Escherichia coli (E. coli).
