α,α‐Difluoroketones possess unique physicochemical properties that are useful for developing therapeutics and probes for chemical biology. To access the α‐allyl‐α,α‐difluoroketone substructure, complementary palladium‐catalyzed decarboxylative allylation reactions were developed to provide linear and branched α‐allyl‐α,α‐difluoroketones. For these orthogonal processes, the fluorination pattern of the
α,α-二氟酮具有独特的理化性质,可用于开发化学生物学的治疗剂和探针。为了获得α-烯丙基-α,α-二氟酮的亚结构,开发了互补的钯催化的脱羧烯丙基化反应,以提供线性和支链的α-烯丙基-α,α-二氟酮。对于这些正交过程,底物的氟化模式使配体能够决定转化的区域选择性。
