    摘要: This invention relates to a process for preparing perfluoroalkyl aryl sulfides by reaction of disulfides with alkali metal salts of aliphatic perfluorocarboxylic acids in the presence of a high-boiling aprotic solvent at elevated temperature and reduced pressure, wherein the product formed is distilled off at the rate at which it is formed. This invention further relates to the novel compounds 2-nitrophenyl pentafluoroethyl sulfide and 2-aminophenyl pentafluoroethyl sulfide.
