Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Molybdooxaziridine Catalysis: Synthesis of α‐Hydroxysulfones From Styrenes Through an ATRA Process

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
This work has discovered that molybdooxaziridine catalysts promote the hydroxysulfonation of substituted α‐methyl‐styrenes using N‐Ts‐hydroxylamine as the nitrogen source. An atom‐transfer‐radical‐addition mechanism involving the stepwise addition of Ts and hydroxy radicals takes place.

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.
