Synthesis of heteroaromatic trifluoromethyl ethers with trifluoromethyl triflate as the source of the trifluoromethoxy group

A series of nitrogen-heterocycles have been transformed to the corresponding trifluoromethyl and higher perfluoroalkyl ethers by the reaction of the <italic>N</italic>-oxides with trifluoromethyl triflate as a bifunctional reagent.
