[Acr-Mes]⁺(BF₄)⁻ serves as a highly stable, bench-accessible superacidic Brønsted acid catalyst, enabling efficient protonation of weakly basic substrates under mild conditions. Its robustness facilitates rapid activation of carbonyl groups, olefins, and heterocycles in multistep syntheses. The trifluoroborate counterion ensures excellent solubility and compatibility with polar reaction media, while the mesityl-substituted acridinium core provides strong electron-withdrawing character and thermal resilience. This reagent functions effectively in protodeboronation, C–H functionalization, and heterocycle formation protocols where precise control over acidity is critical.
