Abstract

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, and mixture of isomers was observed for some examples in the thermal process in DMF.
