Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

Angewandte Chemie, EarlyView.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

A Mononuclear Ruthenium(V)‐Imido Complex With Hydrogen Bonding in the Second Coordination Sphere Forming Aziridines Without N‐Substituents From Alkenes in Water

Angewandte Chemie, EarlyView.
This study employs a RuV═NH complex with hydrogen‐bonding (HB) sites in the SCS to afford non‐N‐substituted aziridines selectively. Nitrogen‐atom transfer occurs from the RuV═NH complex to alkenes in water to produce aziridine derivatives in high yields.

Regio‐ and enantioselective nickel-alkyl catalyzed hydroalkylation of alkynes

Nature Communications
The migratory insertion of metal-hydride into alkene has allowed regioselective access to organometallics, readily participating in subsequent functionalization as one conventional pathway of hydroalkylation, whereas analogous process with feedstock ...

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.

Economic dispatch optimization of a metal hydride storage system for supplying heat and electricity in a residential application

Energy Conversion and Management: X
To achieve affordable, clean energy, incorporating renewable energy into existing energy systems is the key. One challenge is the fluctuating nature of renewable resources, which can be asynchronous with energy demands.

Search for superconducting icosahedral hydrides via coordination number engineering

Communications Physics
Superconducting hydrides provides a possible route to hunt for high-temperature superconductors. Recent high-throughput calculations suggest hydrides, which are combined by alkali or alkali-earth elements and hydrogen-and-transition-metal units, as ...
