Halogenated S-(perfluoroalkyl) dibenzothiophenium salt represented by the following general formula (I). This compound is a new, reactive, and industrially useful reagent for perfluoroalkylating organic compounds. The reagent can be prepared by a one-pot process or a two-step reaction process from a halogenated biphenyl and easily isolated by a filtration method. In addition, the halogenated biphenyl can be recovered by desulfurization from a halogenated dibenzothiophene obtained as a side-product by the usage of the reagent.
