Description

N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate (CAS: 118612-00-3) is a highly specialized organoboron compound with the molecular formula C₃₂H₁₂BF₂₀N. This crystalline salt is widely recognized in advanced chemical research and industrial applications due to its strong Lewis acid characteristics and exceptional thermal stability. Its unique structure, featuring a tetrakis(pentafluorophenyl)borate anion paired with a dimethylanilinium cation, makes it a valuable catalyst or co-catalyst in polymerization reactions, particularly in olefin and metallocene-based systems. The compound’s electron-withdrawing pentafluorophenyl groups enhance its reactivity, while its air- and moisture-sensitive nature requires careful handling under inert conditions. Supplied as a high-purity solid, it is ideal for fine chemical synthesis, materials science, and coordination chemistry studies.

This compound serves as a potent activator in metallocene-catalyzed polymerization, enabling precise control over polymer microstructure. It is also employed in organic synthesis as a weakly coordinating anion (WCA) for stabilizing highly reactive cationic intermediates. Additionally, researchers utilize it in electrochemical applications due to its non-nucleophilic borate anion properties.
