This benzo[d]oxazolium salt features a sterically shielded core with electron-donating methoxy and tert-butyl groups, enhancing stability and solubility in organic media. The tetrafluoroborate counterion enables efficient handling and reactivity in catalytic transformations, particularly in C–H functionalization and photoredox processes.
5,7-Di-tert-butyl-3-(4-methoxyphenyl)benzo[d]oxazol-3-ium tetrafluoroborate serves as a stable, bench-ready benzoxazolium salt that facilitates efficient C–H functionalization and transition-metal-catalyzed cross-coupling reactions. Its electron-rich aryl substituent and sterically protected framework enhance solubility and reaction selectivity, enabling robust coupling with diverse nucleophiles under mild conditions. The tetrafluoroborate counterion ensures excellent handling and compatibility in standard synthetic workflows.
