Ferroceneboronic acid is widely used in organic synthesis, particularly as a building block in Suzuki-Miyaura cross-coupling reactions. Its boronic acid group enables efficient carbon-carbon bond formation with aryl or vinyl halides, making it valuable for constructing conjugated systems in pharmaceuticals and advanced materials. The ferrocenyl moiety adds redox activity, which is exploited in electrochemical sensors and molecular electronics. It is also used in the development of boron-containing organometallic complexes for catalysis and medicinal chemistry, where the combination of boron and ferrocene can enhance stability and bioactivity. Additionally, its unique structure supports research in supramolecular chemistry and responsive materials.
