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.
A gold mediated C−S cross-coupling of aryldiazonium salts with thiols is described. The relevance of the protocol is the use of the readily available and simple gold complex Me2SAuCl. The reaction proceeds under soft conditions and has a broad scope in both the diazonium salt and the thiol.

A Cu-catalyzed cross-coupling reaction of diaryldisulfides or arylthiols with pentafluorobenzene using CuBr as the catalyst, tBuOLi or tBuOK as the base in DMSO at 60 °C under an O2 atmosphere was investigated. The corresponding bisarylthiolation products were obtained in moderate to good yields by C–Hbond and C–Fbondactivation. When 1,10-phenanthroline·H2O and DDQ were added to the above system
