    摘要： Electrochemical fluorination of a thiophene-1,1-dioxide derivative of the formula produces the novel perfluorinated sulphonic acid fluoride of the formula in which X, Y and Z each independently is F, a perfluoroalkyl group having 1 to 8 C-atoms in which one or more CF2 groups may optionally be replaced by oxygen, the oxygen atoms being separated by at least one CF2 group, optionally perfluoroalkyl-substituted cycloperfluoroalkyl group having 5 to 12 C-atoms in which one or more CF2 groups may be replaced by oxygen, or X and Y together denote an optionally perfluoroalkyl-substituted cycloperfluoroalkyl group in which one or more CF2 groups may be replaced by oxygen, Rf each independently is F or a perfluoroalkyl group having 1 to 3 C-atoms, and n and m each independently is 0 or 1. The products are useful as surface active agents.
