Perin, Gelson,Borges, Elton L.,Rosa, Paloma C.,Carvalho, Patrick N.,Lenard?o, Eder J.
, p. 1718 - 1721 (2013/03/28)
Nucleophilic species of selenium were generated in situ from the reaction of diorganyl diselenide with NaBH4 in PEG-400 as solvent and selectively added to several α,β-unsaturated ketones, esters, acid, and nitrile. By this simple procedure, ch

supporting information; experimental part, p. 3886 - 3889 (2010/07/05)
Figure presented A new approach for the synthesis of diorganyl selenides is described. By using economically attractive zinc dust in BMIM-BF4, a series of diorganyl selenides were efficiently achieved in excellent yields, under neutral reaction conditions. Compared to the usual organic solvents, BMIM-BF4 exhibited higher performance with the advantage to be reused up to five successive runs.

Srinivas, Boga,Kumar, Vydyula Pavan,Sridhar, Regati,Reddy, Vutukuri Prakash,Nageswar, Yadavalli Venkata Durga,Rao, Kakulapati Rama
experimental part, p. 1080 - 1084 (2009/10/17)
For the first time, a mild and efficient procedure was developed for the conjugate addition of α,β-unsaturated compounds to benzeneselenol providing β-(phenylseleno)-substituted compounds (Scheme). The reaction was promoted by β-cyclodextrin, proceeded in
Zn/RuCl3-promoted cleavage of diselenides: An efficient michael addition of zinc selenolates to conjugated alkenes in aqueous media
Movassagh, Barahman,Tatar, Ameneh
, p. 1954 - 1956 (2008/03/28)
A simple and highly efficient one-pot route to β-selenocarbonyl compounds and nitriles has been developed by Zn/RuCl3-catalyzed cleavage of diselenides and subsequent Michael addition of zinc selenolates to conjugated alkenes in aqueous media. Georg Thieme Verlag Stuttgart.
A convenient synthesis of β-phenylselenocarbonyl compounds by In-TMSCL promoted cleavage of diphenyl diselenide and subsequent michael addition
Ranu, Brindaban C.,Das, Arijit
, p. 712 - 714 (2007/10/03)
A simple and convenient procedure has been developed for the synthesis of β-phenylselenocarbonyl compounds by a one-pot reaction of diphenyl diselenide and α,β-unsaturated ketones, aldehydes, esters and nitriles in the presence of indium metal-trimethylsilyl chloride under sonication. Presumably, the In-TMSCl reagent system reacts with diphenyl diselenide to form an intermediate, PhSeSiMe3, which then undergoes Michael addition with the α,β-unsaturated carbonyl compounds to produce the products.
CeCl3/Sm system induced reductive cleavage of the Se-Se bond in diaryl diselenides: A novel method for the synthesis of β-selenoesters and β-selenonitriles
Li, Xue,Zhang, Songlin,Wang, Yulu,Zhang, Yongmin
, p. 1111 - 1113 (2007/10/03)
The Se-Se bond in diselenides was reduced by CeCl3/Sm system to produce selenolate anions, which react with α,β-unsaturated esters or α,β-unsaturated nitriles to afford β-selenoesters and β-selenonitriles, respectively.
Zn/Zrcl4 system induced reductive cleavage of the Se-Se bond in diaryl diselenides: A novel method for the synthesis of β-selenoesters and β-selenonitriles
Zhang,Tian
, p. 198 - 199 (2007/10/03)
The Se-Se bond in diselenides was reduced by Zn/ZrCl4 to produce selenolate anions, which react with α,β-unsaturated esters or α,β-unsaturated nitriles to afford β-selenoesters and β-selenonitriles, respectively.
Rapid and precise preparation of reactive benzeneselenolate solutions by reduction of diphenyl diselenide with hydrazine-sodium methanolate
Henriksen, Lars,Stuhr-Hansen, Nicolai
