Bao, Weiliang,Zheng, Yunfa,Zhang, Yongmin,Zhou, Jianqing
, p. 9333 - 9334 (1996)
Allylic and propargyl bromides react smoothly with diorganyl diselenides in aqueous media to give allylic and propargyl selenides in moderate in good yields. The reaction need not he carried out in inert atmosphere. The speed is quicker than the same reactions in organic media.

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.

Selenofuran derivatives were prepared using several phenyl alkenyl selenides via seleno-Claisen rearrangement.
Employment of palladium pincer-complexes in phenylselenylation of organohalides
Wallner, Olov A.,Szabo, Kalman J.
, p. 9215 - 9221 (2005)
Palladium pincer-complex-catalyzed selenylation of propargyl-, allyl-, benzyl-, and benzoyl halides could be achieved under mild reaction conditions employing trimethylstannylphenylselenide as selenylating agent. This reaction has a high functional group
A novel and highly efficient synthetic route to unsymmetrical organoselenides using cesium bases
Cohen, Richard J.,Fox, Daniel L.,Salvatore, Ralph Nicholas
, p. 4265 - 4268 (2004)
A new and convenient one-pot method for the preparation of unsymmetrical selenides has been developed. In the presence of cesium hydroxide, molecular sieves, and DMF, benzeneselenol undergoes direct alkylation with various alkyl halides for the synthesis of alkyl phenyl selenides in moderate to excellent yields. Another method to prepare unsymmetrical organoselenides was also completed by coupling terminal alkynes with benzeneselenyl bromide. As an application, the synthesis of a selenopeptide was also accomplished. Furthermore, this methodology was extended to the synthesis of an organoselenide on solid support.
A novel synthesis of allyl and propargyl selenides promoted by indium
Zheng,Bao,Zhang
, p. 79 - 83 (1997)
Promoted by indium, allylic and propargyl bromides react with diorganyl diselenides in THF to give allylic and propargyl selenides in moderate to good yields.
A new method for the synthesis of allyl arylselenides via the reaction of the zinc allyl selenoates with diaryliodonium salts
Huang, Xian,Xu, Xin-Hua
, p. 801 - 805 (1998)
The insertion of elemental selenium into the Zn-C bond of allylzinc bromide in THF leads to the corresponding zinc allyl selenoate. It reacts with diaryliodonium salts in THF-HMPA to afford the allyl arylselenides in high yields.
Ruthenium(III) chloride catalyzed efficient synthesis of unsymmetrical diorganyl selenides via cleavage of dibenzyl and diphenyl diselenides in the presence of zinc
Zhao, Xiaodan,Yu, Zhengkun,Yan, Shenggang,Wu, Sizhong,Liu, Ren,He, Wei,Wang, Liandi
, p. 7338 - 7341 (2005)
An efficient one-pot route to unsymmetrical diorganyl selenides has been developed by ruthenium-(III) chloride catalyzed reactions of dibenzyl or diphenyl diselenides with alkyl halides in the presence of zinc. Organic iodides, bromides, and activated chlorides underwent the reactions efficiently. Unreactive organic chlorides also underwent the same type of selenation with sodium bromide as the additive.
