A Pd(0)-catalyzed Suzuki-Miyaura coupling reaction of aryl boronic acids with vinyl tosylate provides access to styrene derivatives in good yields. The easily accessible vinyl tosylate represents a stable and less toxic alternative to the vinyl halides and the triflate/nonaflate derivatives. Furthermore, this methodology was expanded using the similar and also readily available 2,2-difluorovinyl tosylate.
