This imidazolium salt features two bulky 2,6-diisopropylphenyl groups that confer exceptional steric protection and solubility in organic media. The tetrafluoroborate counterion enhances stability and facilitates anion exchange in catalytic applications. Designed for use in organocatalysis, this bench-stable cation integrates readily into reaction systems requiring a persistent, electron-deficient carbene precursor under mild conditions.
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate serves as a stable, bench-ready N-heterocyclic carbene precursor with enhanced steric bulk from the 2,6-diisopropylphenyl groups. It facilitates transition-metal-catalyzed cross-coupling reactions and functions effectively in palladium- and nickel-mediated transformations, offering high functional group tolerance and ease of handling. The tetrafluoroborate counterion supports solubility and reactivity in common organic solvents.
