Application

This compound is primarily used as a co-catalyst or activator in olefin polymerization reactions, particularly in metallocene-based systems. It serves as a stabilizing agent for highly electrophilic cations in organic and organometallic synthesis. Researchers also employ it in electrochemical applications and as a dopant in conductive polymers due to its weakly coordinating properties. Its role in generating reactive intermediates for fine chemical synthesis is well-documented.
