Abstract

Abstract: We report the Heck cross-coupling of notoriously unreactive, but synthetically valuable olefins: vinyl sulfoxides, vinyl sulfones, and vinyl sulfides. Key findings include the importance of the sterically hindered (tri-tert-butyl) phosphine ligand and the unique effectiveness of triethylamine as the base. The method is general, E-selective, and can be used to synthesize disubstituted or trisubstituted olefins through simple adjustments of ...
