This difluorovinyl sulfonate ester enables direct C–H functionalization via palladium-catalyzed coupling, offering high stability and compatibility with diverse reaction conditions. The electron-deficient vinyl group facilitates selective addition, while the 4-methylbenzenesulfonate moiety ensures efficient leaving group behavior.
2,2-Difluorovinyl 4-methylbenzenesulfonate serves as a stable, bench-ready electrophilic difluorovinyl transfer reagent. It enables efficient installation of the 2,2-difluorovinyl group under mild conditions, demonstrating broad functional group tolerance and compatibility with palladium-catalyzed cross-coupling reactions. Its robustness facilitates straightforward purification and reliable incorporation into complex molecular architectures.
