Organic Diselenides: Versatile Reagents, Precursors, and Intriguing Biologically Active Compounds

open access: yesCHIMIA, 2017
In this account, we describe how some organic diselenides were successfully used in the past as reagents for asymmetric stereoselective synthesis and more recently as precursors of catalysts and reagents applied in new green protocols.

Regio- and Stereoselective Synthesis of (Z,Z)-Bis(3-amino-3-oxo-1-propenyl) Selenides and Diselenides Based on 2-propynamides: A Novel Family of Diselenides with High Glutathione Peroxidase-like Activity

open access: yesInorganics, 2022
The efficient regio- and stereoselective syntheses of (Z,Z)-bis(3-amino-3-oxo-1-propenyl) selenides and diselenides in high yields based on the nucleophilic addition of sodium selenide to 2-propynamides and sodium diselenide to 3-(trimethylsilyl)-2 ...

Photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides

open access: yesBeilstein Journal of Organic Chemistry, 2013
A novel method of photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides has been developed. Although the arylation reactions with triarylbismuthines are usually catalyzed by transition-metal complexes ...

Diglycosyl diselenides alter redox homeostasis and glucose consumption of infective African trypanosomes

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2017
With the aim to develop compounds able to target multiple metabolic pathways and, thus, to lower the chances of drug resistance, we investigated the anti-trypanosomal activity and selectivity of a series of symmetric diglycosyl diselenides and disulfides.

Chemoselective Reduction of Organoselenocyanates to Diselenides

open access: yesTetrahedron Letters, 1997
Selenocyanates possess an extremely high propensity to produce diselenides on reaction with selenols or selenolates. This is effectively observed when one molar equivalent of metal hydride or lithium triethyl borohydride or one fourth molar equivalent of metal borohydrides are reacted with organic selenocyanates.

Ferromagnetism in 2D Vanadium Diselenide [PDF]

open access: yesACS Nano, 2021
Two-dimensional (2D) Van der Waals ferromagnets carry the promise of ultimately miniature spintronics and information storage devices. Among the newly discovered 2D ferromagnets all inherit the magnetic ordering from their bulk ancestors. Here we report a new 2D ferromagnetic semiconductor at room temperature, 2H phase vanadium diselenide (VSe2) which ...

Synthesis and anticancer activity of bis(2-arylimidazo[1,2-a]pyridin-3-yl) selenides and diselenides: the copper-catalyzed tandem C–H selenation of 2-arylimidazo[1,2-a]pyridine with selenium

open access: yesBeilstein Journal of Organic Chemistry, 2020
Most heteroaryl selenides and diselenides are biologically active, with some reported to act as antioxidants and show activities that are medicinally relevant; hence, the development of efficient methods for their synthesis is an important objective ...

Bis(2,6-di(pyridin-2-yl)pyridin-4-yl)-6,6′-(1,2-diselanediyl)dihexanoate

open access: yesMolbank, 2023
The present paper describes the preparation and characterization of a new dinuclear ligand based on terpyridine featuring a diselenide unit. This new compound was synthesized in a two-step procedure that first involved the insertion of the diselenide ...

Synthesis and Application Dichalcogenides as Radical Reagents with Photochemical Technology

open access: yesMolecules, 2023
Dichalcogenides (disulfides and diselenides), as reactants for organic transformations, are important and widely used because of their potential to react with nucleophiles, electrophilic reagents, and radical precursors.
