A new and more practical method for the preparation of solution‐stable perfluoroalkanesulfenic acids was successfully developed. Starting from perfluoroalkyl iodides, perfluoroalkyl sulfoxides were synthesized by their substitution reaction with alkyl mercaptans and the following oxidation of resulting perfluoroalkyl sulfides with m‐CPBA. Subsequent β‐H elimination of perfluoroalkyl sulfoxides under heating conditions gave the corresponding perfluoroalkanesulfenic acids in good yields. [ABSTRACT FROM AUTHOR]
