The rearrangement of selenium ylides is even today almost unexplored, although it would provide access to important organoselenium compounds with broad downstream applications. In this report, the first systematic study of sigmatropic rearrangement reactions of selenium ylides using a simple rhodium catalyst with catalyst loadings as low as 0.01 mol % is described. Selenium oxide pyrolysis of the rearrangement products gives access to important 1,1-disubstituted butadienes.

Zhang,Su,Li
, p. 313 - 315 (2007/10/03)
In the presence of chlorotrimethylsilane, ytterbium metal can promote the allylation of diselenides with allyl bromide to give the corresponding allylic selenides in good yields under mild and neutral conditions.

Promoted by metallic cadmium which was produced by reduction of CdCl2 · H2O with samarium in situ, allyl bromide and α -bromocarboxylates react with diorgano diselenides in aqueous solutions to give allylic-type selenides and α -selenocarboxylates in moderate to good yields.

Zhan, Zhuangping,Lu, Genliang,Zhang, Yongmin
, p. 280 - 281 (2007/10/03)
Allyl sulfides and allyl selenides are synthesized via the reaction of allyl bromide with disulfides and diselenides promoted by the Sm-BiCl3 system in aqueous media in moderate to good yields.
A Novel Synthesis of Allyl and Prop-2-ynyl Selenides Promoted by Tin in the Presence of Water
Liao, Puhong,Bao, Weiliang,Zhang, Yongmin
, p. 150 - 151 (2007/10/03)
Allylic and prop-2-ynyl (propargyl) bromides react with diorganyl diselenides in the presence of water to give allylic and prop-2-ynyl selenides in moderate to good yields; the reaction rate is faster than for the same reaction in anhydrous organic media.
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 (2007/10/03)
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.
A novel synthesis of allyl and propargyl selenides promoted by indium
Zheng,Bao,Zhang
, p. 79 - 83 (2007/10/03)
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 novel synthesis of allyl and propargyl selenides in aqueous media promoted by indium
Bao, Weiliang,Zheng, Yunfa,Zhang, Yongmin,Zhou, Jianqing
, p. 9333 - 9334 (2007/10/03)
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.
