| Abstract: | Fluorinated olefin‐containing benzothiadiazoles have important applications in optoelectronic materials. Herein, we reported the direct olefination of fluorinated benzothiadiazoles, as catalyzed by palladium. The reaction proceeds under mild reaction conditions and shows high functional‐group compatibility. A preliminary study of the properties of the resulting symmetrical and unsymmetrical olefin‐containing fluorinated benzothiadiazoles in red‐light‐emitting dyes has also been conducted. |
