Hiyama Cross-Coupling Reaction of Aryl Vinylsilanes and Aryl Halides

The Hiyama coupling reaction has emerged as a wildly used method for the construction of C-C bonds, especially in the fields of aryl-aryl and aryl-alkenyl coupling reactions. In general, this protocol highly relies on reactive but unstable silicon reagents such as R-SiF3 and R-Si(OMe)(3). The development of Hiyama coupling reaction involving stable organosilanes is in high demand. In this manuscript, a palladium-catalyzed cross-coupling reaction of aryl vinylsilanes and aryl halides is reported, leading to the formation of Ar-Ar bonds. The reaction has shown good functional group compatibility and offered convenient access to biaryl compounds.
