Palladium-catalyzed arylation of α,α-difluoro-allylic-β-hydroxyester

The aryl-substituted α,α-difluoro-allylic-β-hydroxyesters and aryl-substituted α,α-difluoroketones were obtained via the coupling reaction of aryl iodides with α,α-difluoro-allylic-β-hydroxyester in the presence of Pd(OAc)2 as the catalyst and Et3N as the base.
