Application

4-Cyano-N-(trifluoromethoxy)pyridinium triflimide is a bench-stable trifluoromethoxylation reagent developed in the Togni lab. Under irradiation with visible-light in the presence of a photocatalyst, N-O bond cleavage results in an OCF3 radical capable of arene C-H functionalization, providing trifluoromethoxy ethers.
