Angewandte Chemie, EarlyView.Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes
Angewandte Chemie, EarlyView.Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.

Angewandte Chemie, EarlyView.The first isolable trimetallylenes (SiII)2EII (E = Ge, Sn, Pb) with pπ‐type silanylidenyl donors have been synthesized, having donor–acceptor electronic structures that give rise to near‐infrared absorption and enable access to bis(silanylidenyl)‐supported GeI and SnI radical anions upon one‐electron reduction with elemental potassium. ABSTRACT Herein,

Epitaxial Oxide Interfaces Create Poison‐Resistant CuO Sites for Environmental Catalysis
Angewandte Chemie, EarlyView.An epitaxially stabilized CuO overlayer on Ti1−xInxO2 creates electron‐poor, high‐symmetry Cu–O sites that activate interfacial lattice‐oxygen redox. This interface promotes NOx reduction through an Eley–Rideal pathway, diverts sulfate formation, and sustains CH3SH deep oxidation via a Mars–van Krevelen cycle, offering a route to poison‐resistant ...

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2
Angewandte Chemie, EarlyView.By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...
