The reactions of tin(II) benzenethiolate in DMF with hexafluorobenzene, chloropentafluorobenzene and bromopentafluorobenzene have been compared. Replacement of fluorine and chlorine by the phenylthio group and protodebromination were observed. DMF was a better solvent than either ethylene glycol/pyridine mixture (1:2) or diglyme for the reaction. New products have been isolated and characterized from

A metal-free thiolation reaction between pentafluorobenzene and disulfides by C–H, C–F bond activation and C–S bond formation is reported. Bisthiolated tetrafluorobenzene derivatives would be prepared in moderate to good yields from pentafluorobenzene and disulfides under mild conditions. A possible mechanism for the reaction was given.
