Synthesis of chiral Nβ-protected amino diselenides from the corresponding amino alkyl iodides using NaBH2Se3 as a selenating reagent and their conversion to seleninic acids [PDF]

, 2015
A convenient approach has been presented for the synthesis of Nβ-protected amino diselenides from the corresponding amino alkyl iodides using in situ generated NaBH2Se3 as an efficient selenating reagent.

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

Discovery of new organoselenium compounds as antileishmanial agents [PDF]

Bioorganic Chemistry, 2019
We report new organoselenium compounds bearing the sulfonamide moiety as effective inhibitors of the β-isoform of Carbonic Anhydrase from the unicellular parasitic protozoan L. donovani chagasi. All derivatives were evaluated in vitro for their leishmanicidal activities against Leishmania infantum amastigotes along with their cytotoxicities in human ...

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 ...

Synthesis, Biological Evaluation, and Molecular Docking of Tellurium‐Containing Benzothiazole Derivatives as Enzyme Inhibitors of DNA Gyrase and Dihydrofolate Reductase

BioMed Research International, Volume 2026, Issue 1, 2026.
Tellurium‐containing heterocycles represent an emerging class of organochalcogen compounds with notable redox properties and antimicrobial potential. Incorporation of tellurium into sulfur‐ and nitrogen‐containing frameworks can enhance biological activity through increased polarizability and favorable noncovalent interactions.

Selenium-Epoxy ‘Click’ Reaction and Se-Alkylation—Efficient Access to Organo-Selenium and Selenonium Compounds

Chemistry, 2020
This work establishes the ‘click’ nature of the base-catalyzed oxirane ring opening reaction by the selenolate nucleophile. The ‘click’-generated ß-hydroxy selenide can be alkylated to afford cationic selenium species.
