Synthesis of Unsymmetric Bis(heteroaryl) Selenides by Rhodium‐Catalyzed Exchange Reaction of Heteroaryl Fluorides and Ethers Using Se‐Heteroaryl Carboselenoates

open access: yesEuropean 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.

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

Synthetic Access to Alkali Metal Selenides via Ball Milling

open access: yesZeitschrift 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

Thermal Phase‐Modulation of Thickness‐Dependent CVD‐Grown 2D In2Se3

open access: yesAdvanced Functional Materials, Volume 36, Issue 12, 9 February 2026.
A comprehensive study of CVD‐grown 2D In2Se3 reveals a distinct thickness‐dependent phase landscape and a reversible, thermally driven transformation between β″ and β* variants. In situ TEM electron diffraction and Raman spectroscopy reveal structural dynamics, while the structural invariance of the α‐phase in ultrathin regimes highlights its stability—
