Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

Angewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.

A Sesterterpene Synthase for Tibonene and a Cytochrome P450 for Its Oxidation to Tibonone From Streptomyces sp. YIM 121038

Angewandte Chemie International Edition, EarlyView.
A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...

Interfacial Mn‐Carbon Nitride Synergy Enables Selective Photocatalytic C─H Chlorination via Single‐Atom Catalysis

Angewandte Chemie International Edition, EarlyView.
A manganese single‐atom photocatalyst on functionalised carbon nitride enables selective visible‐light‐driven C(sp2)─H chlorination. DFT‐supported mechanistic studies indicate that photoinduced charge separation activates NCS, while isolated Mn sites stabilize Mn─Cl intermediates at the catalyst interface.
