Herein, we report a general and efficient method for the palladium‐catalyzed remote C(sp2)−H difluoroalkylation of N‐aryloxazolidinone derivatives with commercially available difluoroalkyl bromide. This method tolerates a wide range of functional groups with 26 examples in up to 96 % yields. Moreover, it proceeds with complete para‐selectivity. Preliminary mechanistic studies indicated that a single
