Krief, Alain,Dumont, Willy,Denis, Jean-Noel,Evrard, Guy,Norberg, Bernadette
, p. 569 - 570 (1985)
The propensity of several reagents to oxidize selenides to selenones has been evalueted; the scope and limitations of the methods are presented.
Corey-Chaykovsky Cyclopropanation of Nitronaphthalenes: Access to Benzonorcaradienes and Related Systems

Nitronaphthalene derivatives react as Michael acceptors in the Corey-Chaykovsky reaction with alkyl phenyl selenones and alkyl diphenyl sulfonium salts. Mechanistic studies reveal that sterically demanding substituents at the carbanionic center favor formation of cyclopropanes and suppress competitive β-elimination to the alkylated products. The transformation, demonstrated also on heterocyclic nitroquinoline and nitroindazolines, is an example of transition metal-free dearomatization method.
NOVEL SYNTHESIS OF SELENONES : Application to the Synthesis of Alkyl Cyclopropanecarboxylates.
Krief, A.,Dumont W.,De Mahieu, A.F.
, p. 3269 - 3272 (2007/10/02)
Selenones are prepared by oxidation of selenides by hydrogen peroxide-benzeneseleninic acid.They react with α,β-unsaturated esters and alkylidene malonates in the presence of t-BuOK and produce alkyl cyclopropanecarboxylates.
