A newpreparationmethod of 1,1,2,2-tetrafluoro-2-(trifluoroethenyloxy)-ethanesulfonyl fluoride (8) has been developed utilizing the unique performance of the imidazole protectivegroup. Namely, the electrodonating character of the imidazole protectivegroup on the sulfonyl group enables the formation of the novel intermediate monomer, which can be easily converted to 8 by the reaction with HF.
