Palladium-Catalyzed Diversified Synthesis of Monofluorinated Alkenes from Allylic -Difluorides through Pd-OH Intermediate.

Significant advancements in synthesis of monofluoroalkenes via palladium-catalyzed reactions involving allylic -difluorides and diverse nucleophiles have been achieved. This method allows regioselective arylation, alkylation, allylation, alkenylation, and hydrogenation of allylic -difluorides, yielding high selectivity and favorable product yields under mild conditions. Tolerating various functional groups, these transformations utilize a common Pd-OH intermediate. Additionally, employing triple Pd-catalyzed cross-coupling yields diverse trisubstituted alkenes efficiently.
