Application

B-[(1E)-2-(3-Fluorophenyl)ethenyl]boronic acid is widely used in Suzuki-Miyaura cross-coupling reactions to introduce fluorinated styrenyl motifs into complex organic frameworks. It serves as a key intermediate in the synthesis of fluorinated pharmaceuticals, agrochemicals, and functional materials. Researchers leverage its boronic acid group for selective C-C bond formation under mild conditions. The 3-fluorophenyl moiety enhances electronic properties in conjugated systems, making it valuable for OLED and liquid crystal development. Its stability and reactivity also support combinatorial chemistry and high-throughput screening applications.
