Bromonitroalkanes in Organic Synthesis
European Journal of Organic Chemistry, EarlyView.α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical, carbanion, and carbocation synthons. This mini‐review summarizes the different reaction modes and highlights recent developments in thermal and photochemical processes. α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical,

Metal-Free Aziridination of Unactivated Olefins via Transient N-Pyridinium Iminoiodinanes [PDF]
We describe a metal-free aziridination of unactivated olefins to generate N-pyridinium aziridines, which participate in cross-coupling to afford N-aryl aziridines and reductive depyridylation to afford N–H aziridines.

NADH and Nonnatural Dihydronicotinamides (NAH) as Reagents in Organic Synthesis and Catalysis
European Journal of Organic Chemistry, EarlyView.NADH and synthetic 1,4‐dihydronicotinamides (NAH) are versatile redox reagents that extend beyond biological hydride transfer. This review highlights their development as nonenzymatic reagents in organic synthesis, from polar to radical reactivity and ultimately to applications in complex biological environments.

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

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.
