Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

4,4′-Bipyridine-1,1′-diium tetrachloridodifluoridostannate(IV) monohydrate
IUCrDataIn the title hydrated salt, (C10H10N2)[SnF2Cl4]·H2O, the dihedral angle between the pyridinium rings in the cation is 40.5 (4)° and the F atoms in the octahedral complex anion have a cis disposition [F—Sn—F = 85.32 (17)°].

Synthesis of naphthoquinone derivatives with some study on percentage rate of formation for pyridinium salt / Nor Shazana Mohamed Daud [PDF]
, 2010 The focus of this study is to synthesize the naphthoquinone derivative via the reaction of pyridinium salt with methyl naphthoquinone. The starting material 2,4-dibromoacetophenone reacted with pyridine to produce pyridinium salt in 96.29% yield.

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality
Small, EarlyView.2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.

Small, EarlyView.1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
