Atomic Symbiotic‐Catalyst for Low‐Temperature Zinc‐Air Battery

open access: yesAngewandte Chemie, EarlyView.
A new “atomic symbiotic‐catalyst” system comprising single‐atom MNx and local sp3 carbon defects is proposed, which marries the advantages of typical single‐/dual‐atom catalysts while addressing their respective weaknesses, thus synergistically achieves high electrocatalytic activity and battery efficiency.

Synthetische Ansätze für Molekül‐2D‐Übergangsmetalldichalkogenid‐Heterostrukturen

open access: yesAngewandte Chemie, EarlyView.
Die Integration von 2D‐Materialien in die Molekularchemie ermöglicht eine präzise Kontrolle über die Materialeigenschaften und verbessert deren Funktionalität. Molekül‐Übergangsmetalldichalkogenid‐Heterostrukturen (mTMDs, engl.: molecule‐transition metal dichalcogenides) sind aufgrund ihrer einzigartigen elektronischen, optischen und katalytischen ...

Avoiding the Kauzmann Paradox via Interface‐Driven Divergence in States

open access: yesAngewandte Chemie, EarlyView.
Interface‐driven stress in core‐shell particle architecture caused by surface speciation creates divergence of associated stress vectors, resulting in nonequilibrium fluxes and deep supercooling. Analysis of nonequilibrium phase models reveals that the addition of an intermediary interfacial state results in evolution in the thermodynamic speed limits ...

Ion‐Pair Hydrogen Atom Transfer Catalysis Enables Cr‐Catalyzed Allylation of Ketones Using Hydrocarbon Alkenes

open access: yesAngewandte Chemie, EarlyView.
We developed the allylation of ketones using simple alkenes promoted by a chromocene catalyst and an ion‐pair hydrogen atom transfer (IP‐HAT) catalyst. This catalytic system can be applied to a wide range of ketones, including aliphatic ketones. The reaction proceeds under mild conditions with high functional group tolerance.

Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria

open access: yesAngewandte Chemie, EarlyView.
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.
