A highly regio- and stereoselective coupling of (Z)-1,2-bis(aryl(alkyl)thio)alkenes and Grignard reagents in the presence of a Ni catalyst under mild conditions enables an efficient route for the synthesis of (Z)-vinylic sulfides. (Z)-vinylic sulfides are important intermediates in the synthesis of tri- and tetrasubstituted alkenes.
