Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

Chemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

Exploring Calixarene‐Based Pseudorotaxane Architectures: Threading Ammonium Axles With an Exo‐Rim π‐Functionalized Calix[6]Arene Macrocycle

Chemistry – A European Journal, EarlyView.
This research presents a novel 1,4‐π‐functionalized calix[6]arene with enhanced interactions with dialkylammonium axles. We investigate threading behavior in CDCl3, highlighting how exo‐rim π‐functionalization affects binding affinity and stereoselectivity.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Cross‐Dehydrogenative Coupling Reactions With Redox‐Active Guanidine Reagents

Chemistry – A European Journal, EarlyView.
ABSTRACT Cross‐dehydrogenative coupling (CDC) reactions are attractive and environmentally friendly ways to form new C‐C and other element‐element bonds. Here, we report the first CDC reactions triggered by a redox‐active guanidine reagent. N‐phenyltetrahydroisoquinoline and derivatives with electron‐donating and withdrawing substituents at the N ...
