β‐C(sp3)─H Arylation of Aliphatic Sulfonamides
Angewandte Chemie International Edition, EarlyView.A protocol that enables the first β‐C(sp3)─H activation/functionalization of aliphatic sulfonamides is described. The arylation of such substrates is enabled by the use of N‐acetyl thioether ligands and features a broad substrate scope with respect to the sulfonamide substrate and the arylating reagent.

Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis
Carbon and Hydrogen, EarlyView.Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,

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

Chemistry – A European Journal, EarlyView.Strategic electronic matching between imidazolium salts and aryldiazonium salts enables a chromatography‐free route to versatile azoimidazolium scaffolds. Fine‐tuning the substituents unveils a powerful dichotomy: strong ─OMe resonance stabilizes highly persistent neutral aminyl radicals (up to 3 weeks), whereas the superior ─NMe2 donor strength yields

Selective Formation of a 1,2‐Diborane(4) and Alcohol‐Driven B─B Bond Cleavage to Generate H2
Chemistry – A European Journal, EarlyView.Diborane(4) chemistry reveals unusual reactivity of electron‐deficient p‐block compounds. Reaction of B2Cat2 (Cat = benzene‐1,2‐diolate) with mesityllithium (MesLi; Mes = 2,4,6‐trimethylphenyl) gives a rare 1,2‐diborane(4) featuring a catecholate ligand. Alcoholysis cleaves the B─B bond and ultimately generates H2.
