Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry
Angewandte Chemie, EarlyView.Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Bond Length as a Unified Descriptor for Stable Iodine Battery
Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.Charge transfer induced by the interactions between iodine and ligands leads to the elongation of the I–I bond. This resulting bond length correlates directly with coordination strength, serving as a unified descriptor for the rational design of both cathode hosts and electrolyte components.

Precision Switching and Coupled Motion in a [3]Rotaxane Molecular Machine
Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.A [3]rotaxane, composed by two crown ether macrocycles and an axle presenting three recognition sites, is operated through both chemical and electrochemical stimuli. The position of the macrocycles is precisely controlled by sequential stimulation and the processes are fully reversible. The characterization of the system revealed the macrocycles affect

Chemistry – A European Journal, EarlyView.Starting from carboxylic acids and Selectfluor‐derivatives, functionalized diazabicyclooctanes can be obtained via a novel Polonovski‐type rearrangement proceeding under mild reaction conditions. Besides their use in organic synthesis the unique structure and reactivity of the rearrangement products enables applications in medicinal chemistry ...

Diorganotelluride···N Chalcogen Bonds: Analysis and Tuning of Two σ‐Holes
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Two new chalcogen bond aggregates were analyzed using single crystal X‐ray diffraction: an oligomeric ChB aggregate between bis(pentafluorophenyl) telluride and DABCO, and a monoadduct between (pentafluorophenyl)(phenyl) telluride and quinuclidine. In addition to some of the shortest intermolecular Te···N contacts reported, these structures provide ...
