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

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.

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 ...

NiH-Catalyzed Enantio- and Regioselective Hydroselenylation of Unactivated Alkenes. [PDF]

open access: yesAdv Sci (Weinh)
Nickel‐hydride‐catalyzed enantio‐ and regioselective hydroselenylation of unactivated alkenes provides access to chiral organoselenium compounds. Enantiodetermining Ni–H insertion followed by single‐electron diselenide activation generates selenyl radical.

Electrochemical use of chiral non-racemic diselenides [PDF]

open access: yes
An electrochemical approach has previously been described for the selenenylation-deselenenylation of alkenes using diphenyl diselenide. The use of electrochemistry enabled diphenyl diselenide to be used in catalytic amounts to convert alkenes into ...

Electrochemically Driven Regioselective Radical Functionalization of Allenes: Scope and Mechanistic Insights. [PDF]

open access: yesAdv Sci (Weinh)
Allenes emerge as powerful platforms for electrochemical functionalization through radical pathways. Selective radical addition at the central carbon triggers anodic oxidation and intramolecular cyclization, enabling efficient synthesis of oxazolines and oxazolidine‐2‐imines without external oxidants.

The Influence of Long Carbon Chains on the Antioxidant and Anticancer Properties of N-Substituted Benzisoselenazolones and Corresponding Diselenides

open access: yesPharmaceuticals, 2023
Organoselenium compounds are well-known for their numerous biocapacities, which result from the uniqueness of the selenium atom and the possibility of constructing heterorganic molecules that can mimic the activity of selenoenzymes, crucial for a ...

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.
