Description

Potassium Tetrakis[3,5-Bis(Trifluoromethyl)Phenyl]Borate is a highly fluorinated, weakly coordinating anion (WCA) salt, essential for stabilizing reactive cationic intermediates and catalysts. Its primary value lies in its exceptional chemical inertness and solubility in non-polar organic media, making it a superior counterion in organometallic chemistry and polymerization processes. This compound is critically needed by researchers and manufacturers in the fields of advanced materials science, specialty polymer synthesis, and homogeneous catalysis development.

Application

• As a non-coordinating counterion in cationic polymerization catalysts (e.g., for olefins and styrenes).
• As a key component in electrolyte salts for advanced lithium-ion and lithium-metal batteries.
• For the stabilization of highly electrophilic cations and Lewis acid catalysts in organic synthesis.
• In the preparation of photoinitiator systems and photoacid generators for UV-curable coatings and photoresists.
• As a supporting electrolyte in electrochemical studies due to its wide electrochemical window.
• For the synthesis of ionic liquids with tailored properties for separation and catalysis.
• In olefin metathesis and other transition metal-catalyzed reactions requiring weakly coordinating anions.
