Sulfur fluorides SF6, ClSF5 and CF3SF5 were reacted with C6H6, C6H5Br and C6H5Cl in a low temperature radio-frequency plasma. Due to the stepwise dissociation of sulfur fluorides, the fluorination of benzenes was observed. In all reaction products C6H5SF5 was found in minor quantities, and BrC6H4SF5 or ClC6H4SF5 along with numerous halogenated benzenes when C6H5Br or C6H5Cl were used as reactants, respectively.
