This benzo[d]oxazolium salt features a sterically shielded core with electron-deficient aromatic character, enabling stable cationic functionality under standard conditions. The para-trifluoromethoxyphenyl group enhances solubility and modulates electronic properties, while the tetrafluoroborate counterion ensures high crystallinity and ease of handling. Designed for use in catalytic systems and functional materials.
5,7-Di-tert-butyl-3-(4-(trifluoromethoxy)phenyl)benzo[d]oxazol-3-ium tetrafluoroborate serves as a stable, bench-ready benzoxazolium salt that facilitates C–H functionalization and transition-metal-catalyzed coupling reactions. The electron-rich aryl substituent and sterically protected core enable high functional group tolerance and ease of purification. Its robustness under standard synthetic conditions makes it a practical building block for constructing complex heterocyclic scaffolds in medicinal chemistry and materials science applications.
