A stepwise conversion of a disulfide (SS) to a diselenide (SeSe) bond through the corresponding iodide intermediate was implemented and was applied to the synthesis of selenocystamine and l-selenocystine derivatives from cystamine and l-cystine, respectively, in moderate yields.

Reactions of selenium with imines (RR1C=NR2) of aldehydes and ketones in the presence of carbon monoxide, water and triethylamine lead to reductive selenation, on aerobic work-up, to afford symmetrical diselenides (RR1CHSe)2 in good to excellent yields. The proposed mechanism suggests that both in situ generated carbonyl selenide (SeCO) and hydrogen selenide (H2Se) are involved in the reaction.
Condition-driven selective syntheses of dialkyl diselenides involving elemental selenium and sodium borohydride
Krief, Alain,Derock, Michel
, p. 1012 - 1014 (2007/10/03)
Dialkyl diselenides have been prepared from alkyl halides, sodium borohydride and elemental selenium using two different methods. One of them involves the intermediate formation of diselenide dianion equivalent ( -SeSe-).
Synthesis of diselenides and selenides from elemental selenium
Krief, Alain,Derock, Michel
, p. 3083 - 3086 (2007/10/03)
Sodium hydride is able to reduce elemental selenium to sodium diselenide (Na2Se2), but not to sodium selenide (Na2Se). Dialkyl diselenides and even dialkyl selenides, including unsymmetrical dialkyl selenides, can be nevertheless synthesized using the proper Se/NaH ratio (1/1 or 1/2).
The first synthesis of organic diselenolates: Application to the synthesis of diorganyl diselenides
Krief, Alain,Van Wemmel, Thierry,Redon, Martine,Dumont, Willy,Delmotte, Cathy
, p. 2245 - 2247 (2007/10/03)
The addition of elemental selenium to organolithium compounds 1 or organic selenates 2 gives organic diselenolates 3. The reactions proceed by the insertion of two selenium atoms into the carbon-metal bonds or of one selenium atom into a selenolate. Evidence for the existence of n- butyldisilenol has also been obtained.
