Potassium tetrakis(pentafluorophenyl)borate

Potassium tetrakis(pentafluorophenyl)borate (Cat No.:L002806) is a highly lipophilic, non-coordinating salt widely used in organometallic and coordination chemistry. The bulky and electron-deficient tetrakis(pentafluorophenyl)borate anion stabilizes reactive cationic metal complexes without interfering in catalytic cycles. It is especially valuable in olefin polymerization, metathesis reactions, and the generation of stable carbocations or electrophilic species. The potassium counterion provides good solubility in polar organic solvents. Due to its weakly coordinating nature, it plays a critical role in studying and optimizing the reactivity of transition metal catalysts and highly electrophilic intermediates.
