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.

Benson J Jelier et al.

A simple trifluoromethoxylation method enables non-directed functionalization of C-H bonds on a range of substrates, providing access to aryl trifluoromethyl ethers. This light-driven process is distinctly different from conventional procedures and occurs through an OCF3 radical mechanism mediated by a
