Sulfinyl‐directed peri‐selective C−H fluoroalkoxylation of arylsulfoxides with fluorinated alcohols has been developed. By means of a palladium catalyst and PhI(OAc)2 as an oxidant, a range of fluoroalkoxy groups can be installed onto the peri position of arylsulfoxides. The remaining sulfinyl groups on the fluoroalkoxylation products further promote Pummerer‐based C−H functionalizations.
