| Abstract: | This work emphasizes the synthesis of substituted vinyl arenes by reductive coupling of aryl halides with vinyl bromides under mild and easy‐to‐operate nickel‐catalyzed reaction conditions. A broad range of aryl halides, including heteroaromatics, and vinyl bromides were employed to yielding products in moderate to excellent yields with high functional‐group tolerance. The nickel‐catalytic system displays good chemoselectivity between the two C(sp2)‐halide coupling partners, thus demonstrating a mechanistic pathway distinct from other stepwise protocols. |
