Sodium Tetrakis Pentafluorophenyl Borate is primarily used as a weakly coordinating anion in catalytic systems, enabling efficient olefin polymerization and metathesis reactions. Its fluorinated structure enhances solubility in nonpolar media, making it ideal for electrochemical applications such as lithium-ion battery electrolytes. Researchers also employ it as a counterion for stabilizing highly reactive cations in organometallic chemistry. In materials science, it serves as a dopant for conductive polymers to improve charge transport properties.
