An Efficient Method for the Preparation of Pentafluoroiodoethane from Chloropentafluoroethane

Abstract An efficient method was developed for the synthesis of pentafluoroiodoethane from chloropentafluoroethane. Sulfinatodechlorination of CF 3 CF 2 Cl was carefully investigated. Subsequent iodination can be conducted in one pot without further purification, giving the corresponding CF 3 CF 2 I in practically acceptable yield.
