Zinc simple: The loading‐dependent zinc‐mediated addition of benzyl bromides to alkynes is the key step for the formation of vinyl bromides. In combination with a palladium‐catalyzed Suzuki cross‐coupling reaction with boronic acids, tri‐ and tetrasubstituted alkenes were obtained in good yields and stereoselectivities in a one‐pot protocol (see scheme).
