New 4-pentafluorosulfanyl and 4-perfluoroalkylthio derivatives of 1-chloro-2-nitrobenzene and 1-chloro-2,6-dinitrobenzene were prepared from the corresponding bis(4-chloro-3-nitrophenyl)disulfide and bis(4-chloro-3,5-dinitrophenyl)disulfide, respectively. The SF5 derivatives were obtained by fluorination of the disulfides with AgF2 according to Sheppard’s method, while perfluoroalkylation was carried

importance of copper (and other coinage metals) in W.A. Sheppard's original synthesis of SF5-benzenes [2] as well as a new route to SF5-benzenes involving the direct fluorination of aromatic sulfenyl chlorides (Ar–S–Cl). Further nucleophilic substitution chemistry of the active halogen atom in 1-chloro-2,6-dinitrobenzene-4-pentafluorosulfanylbenzene will be presented, including chemistry aimed at potentially
