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.

Promoted by metallic cadmium which was produced by reduction of CdCl2 . H2O with samarium in situ, allyl bromide and a -bromocarboxylates react with diorgano diselenides in aqueous solutions to give allylic-type selenides and a -selenocarboxylates in moderate to good yields.
A novel synthesis of allyl and propargyl selenides in aqueous media promoted by indium
Allylic and propargyl bromides react smoothly with diorganyl diselenides in aqueous media to give allylic and propargyl selenides in moderate to good yields. The reaction need not be carried out in inert atmosphere. The speed is quicker than the same reactions in organic media. Copyright (C) 1996 Elsevier Science Ltd
