Toward Industrial Electrosynthesis of Ethylene: Energy‐Efficient and Stable Acetylene Semi‐Hydrogenation on a Copper Phosphide/MXene Electrocatalyst

Angewandte Chemie, EarlyView.
Cu3P nanoparticles anchored on MXene via Ti─O─P bonds exhibit enhanced stability and resist agglomeration during the electrochemical semi‐hydrogenation of C2H2 to C2H4. Ti3C2/Cu3P achieves a record energy efficiency of 23.0% at 0.2 A cm−2 and stable operation in a 4 cm2 MEA for over 100 h at 1.0 A.

Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

Angewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Non‐Statistical Assembly of Donor–Acceptor Cages for Light‐Induced Charge Separation

Angewandte Chemie, EarlyView.
Donor–acceptor functionalized cages [Pd2D2A2]4+ with defined stoichiometry and stereoconfiguration were assembled in a single step by employing the shape complementary assembly (SCA) strategy. While the redox functionalities remain largely independent in the ground state, photoexcitation results in ultrafast ligand‐to‐ligand charge transfer, as ...
