• Vinylic sulfides
• Vinylic selenides
• Vinylic tellurides
• Nickel catalysis

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 stereo-selective for the nickel catalyzed substitution, and mixture of isomers was observed for some examples in the thermal process in DMF.
