Enantioselective Growth of Chiral Serine‐Induced β‐Ag2Se Crystals from an Organoselenium Compound
Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.Chiral amino acids direct the enantioselective crystallization of β‐Ag2Se nanocrystals from an organoselenium precursor. L‐ and D‐serine induce distinct morphologies and opposite homochiral adsorption preferences, transferring molecular handedness into the inorganic lattice.

Next‐Generation Antioxidant Strategies: From Nanoformulations to Gene‐Targeted Therapies
cScience, Volume 2, Issue 1, March 2026.ABSTRACT Antioxidants play a pivotal role in neutralizing oxidative stress, a key factor in aging and chronic diseases such as cancer, cardiovascular disorders, and neurodegeneration. Although traditional antioxidants such as vitamins C and E, polyphenols, and endogenous enzymes have shown efficacy in laboratory and clinical studies, their therapeutic ...

European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.Various unsymmetric bis(heteroaryl) selenides are synthesized by the rhodium‐catalyzed exchange reaction of heteroaryl fluorides and ethers with Se‐heteroaryl 1‐adamatanecarboselenoates. The synthetic method is applicable to a broad range of five‐ and six‐membered heteroaryl derivatives and provides compounds containing multiple heteroatoms.

Synthetic Access to Alkali Metal Selenides via Ball Milling
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.We report the synthesis of alkali metal selenides through reactive ball milling under an argon atmosphere. This mechanochemical pathway is solvent‐free and can be performed at room temperature within minutes to hours. The synthesis of several sodium polyselenides (Na2Sen) and alkali metal selenides (A2Se, A = K, Rb, Cs) is investigated and the received

Organoselenium-Catalyzed Asymmetric Cyclopropanations of (E)‑Chalcones
We report a new class of chiral tetrahydroselenophene based on (S)-diphenyl(tetrahydroselenophen-2-yl)methanol, which was prepared from (R)-3-(3-bromopropyl)-2,2-diphenyloxirane and sodium selenide.

Preparation of Se(IV) Aryltrifluoromethylselenide Dichlorides
European Journal of Organic Chemistry, Volume 29, Issue 1, January 12, 2026.An efficient synthesis of dichloro(aryl)(trifluoromethyl)‐λ4‐selanes via chlorination of aryl trifluoromethylselenides with SO2Cl2 is reported. The compounds were fully characterized and their stability studied. Density functional theory studies reveal an asynchronous concerted, exergonic pathway, while formation of the Se(VI) derivative is both ...
