Potassium 4-fluorophenyltrifluoroborate

Description:
Potassium 4-fluorophenyltrifluoroborate is an organoboron compound characterized by its trifluoroborate group and a 4-fluorophenyl moiety. This compound typically appears as a white to off-white solid and is soluble in polar organic solvents. It is known for its utility in organic synthesis, particularly in cross-coupling reactions, such as Suzuki-Miyaura coupling, where it serves as a boron source for the introduction of the 4-fluorophenyl group into various substrates. The presence of the trifluoroborate group enhances its reactivity and stability compared to other boron compounds. Additionally, the fluorine atom in the para position can influence the electronic properties of the aromatic ring, making it a valuable building block in the synthesis of pharmaceuticals and agrochemicals. Safety data indicates that, like many organoboron compounds, it should be handled with care, as it may pose health risks if ingested or inhaled. Proper laboratory practices and personal protective equipment are recommended when working with this substance.
