Diselenide‐Catalyzed Asymmetric Allenylation of Alkynes

European Journal of Organic Chemistry, Volume 29, Issue 11, 16 March 2026.
An asymmetric allenylation of alkynes is described using chiral lactamides‐based diselenides under oxidative conditions. This led to the corresponding allenylamides with enantiomeric excesses up to 72%, and uncovers an interesting stereodivergency feature related to the β‐H‐syn‐elimination of transient Se(IV) intermediates.

pH-Dependent Fe (II) pathophysiology and protective effect of an organoselenium compound [PDF]

, 2009
Influence of pH on the extent of lipid peroxidation and the anti-oxidant potential of an organoselenium compound is explored. Acidosis increased the rate of lipid peroxidation both in the absence and presence of Fe (II) in rat’s brain, kidney and liver ...

Organoselenium compounds as mimics of selenoproteins and thiol modifier agents

, 2017
Here, we critically review the literature on the capacity of organoselenium compounds to mimic selenoproteins (particularly GPx) and discuss some of the bottlenecks in the field.

Bioinspired Use of Organoselenium Catalysts

Proceedings of The 15th International Electronic Conference on Synthetic Organic Chemistry, 2011
Selenium-based reagents bear a high potential for the improvement of known reactions not only from an environmental and pharmaceutical point of view, but also as interesting reagents for the development of, completely new synthetic transformations and as potential ligands in catalytic reactions. A variety of organoselenium compounds have been proven to

Xerogel-Sequestered Silanated Organochalcogenide Catalysts for Bromination with Hydrogen Peroxide and Sodium Bromide

Molecules, 2015
While H2O2 is a powerful oxidant, decomposing into environmentally benign H2O and O2, a catalyst is often required for reactions with H2O2 to proceed at synthetically useful rates.
