Chemistry – A European Journal, EarlyView.This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Self‐Immolative Poly(Benzyl Ether)s: Design Principles and Controlled Depolymerization
Chemistry – A European Journal, EarlyView.Unzipping to Sustainability: This Concept article explores the thermodynamic design of quinone‐methide (QM)‐based poly(benzyl ether)s (PBEs). It explains how a low ceiling temperature (Tc), QM stability, and an entropic gain drive rapid depolymerization (“unzipping”) of PBEs into monomers.

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry
Chemistry – A European Journal, EarlyView.Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.

Development of Blue‐to‐Near‐Infrared rTCO–Caged Fluorogenic Probes for Click‐to‐Release Monitoring
Chemistry – A European Journal, EarlyView.A series of fluorogenic rTCO‐caged click‐to‐release probes was prepared and evaluated both in a cuvette and in live cells. Some of the probes exhibited significant turn‐on and efficient fluorophore release spanning the blue‐to‐NIR region. A significant difference in the performance of the compounds in live cells was observed, highlighting the need for ...

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins
Chemistry – A European Journal, EarlyView.C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Alkyne‐Assisted Stereospecific Skeletal Rearrangement via Nonclassical Carbocations
Chemistry – A European Journal, EarlyView.We report stereospecific nucleophilic substitution of homopropargylic alcohols enabled by alkyne anchimeric assistance. Alcohol activation triggers formation of a nonclassical cyclopropylidenemethyl cation, allowing efficient chirality transfer to densely substituted tertiary homopropargyl fluorides.

Palladium-catalyzed selective activation of allyl alcohols as allyl cations, allyl anions, and zwitterionic trimethylenemethanes [PDF]
Pd-Et3B catalytic system promotes the generation of allyl cations, allyl anions, and zwitterionic trimethylenemethane species from the corresponding allylic alcohols. Allyl cations react with a wide variety of nucleophiles, e.g., amines, active methylene

ChemSusChem, Volume 18, Issue 6, March 15, 2025.we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the
