Photochemistry of organoselenium compounds
Journal of the Chemical Society, Chemical Communications, 1974Irradiation of dibenzyl diselenide (l) with 350 nm light in the presence of oxygen afforded benzaldehyde and elemental selenium, whereas irradiation in the absence of oxygen produced dibenzyl monoselenide (ll); irradiation of dibenzyl triselenocarbonate (III) produced dibenzyl diselenide.

Abstract Organoselenium chemistry is proving increasingly valuable to the synthetic organic chemist. Selenium residues are easily introduced into organic molecules, they serve to effect a variety of useful transformations, and are easily removed at the end of the sequence. These processes are often characterized by high chemo- regio- and

Aspects of Organoselenium Chemistry
Phosphorus, Sulfur, and Silicon and the Related Elements, 1998Monoselenophosphate, SePO3H3-n n-, has been chemically synthesized and characterized. It has been shown to be identical with the biological selenium donor SePX. Hydrolysis of selenophosphate is pH dependent and maximal at about pH 7. The dianion is the species which hydrolyzes fastest.

Organoselenium substituted poly(p-phylenenvinylene)
Heteroatom Chemistry, 2005A new type of conjugated polymer, organoselenium substituted poly(p-phenyleneviny- lene) (PPV), was synthesized from the corresponding alkylselenenyl p-xylylene dibromide via a Gilch route using potassium tert-butoxide in THF. The p-xylylene dibromide precursors were synthesized by reacting lithiated bis(methoxymethyl)benzenes with elemental selenium ...

Organoselenium chemistry: an overview
1999Abstract Organoselenium compounds have been known since the nineteenth century. Early examples included simple alkyl selenols, selenides, selenoxides and diselenides, which often proved to be highly malodorous, unstable, and generally unpleasant to handle.
