scheme or table, p. 3787 - 3790 (2009/04/06)
A general method for the synthesis of vinylic chalcogenides by nucleophilic and Ni-catalyzed vinylic substitution on vinylic halides by phenyl chalcogenolates is described. The reactions were regio and stereoselective for the nickel catalyzed substitution

The indium(III) selenolate obtained from indium(I) bromide and diphenyldiselenide promotes, alternatively, the Markovnikov hydroselenation, diselenation or hydration of terminal alkynes, depending on the experimental conditions. Georg Thieme Verlag Stuttgart.
Palladium-catalyzed hydroselenation of allenes with benzeneselenol

Palladium(II) acetate (Pd(OAc)2) catalyzes the addition of benzeneselenol to allenes, providing the corresponding vinylic selenides in good yields. In contrast to the oxygen-induced radical addition of PhSell to terminal allenes, which occurred at the terminal double bond preferentially, the present palladium-catalyzed hydroselenation to terminal allenes affords the internal adduct preferentially; thus, these two reactions are complementary to each other for the synthesis of vinylic selenides.
