Abstract

AbstractWe 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 stoichiometry.magnified image
