has been developed. The selection of the 2‐pyridyl group as the aryl substitute on the sulfone is critically important for the success of this transformation (see scheme). The synthetic application of fluorinated sulfones is extended and a unique solution is provided for a long‐standing challenge in nucleophilic difluoro(sulfonato)methylation reactions.
