The organic superbase t-Bu-P4-catalyzed direct thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates was developed. Yields of perfluorophenylsulfides of up to 97% under catalysis of 5 mol% t-Bu-P4 were achieved. This method was shown to provide an efficient way to construct the perfluorophenyl–sulfur bond under mild metal-free reaction conditions.

Palladium(II)/Copper(II)-Catalyzed C-H Sulfidation or Selenation of Arenes Leading to Unsymmetrical Sulfides and Selenides
C–H sulfidation or selenation of arenes by a Pd(II)/Cu(II) catalytic system: Preparation of unsymmetrical sulfides or selenides by C–H functionalization has been disclosed. This protocol could be applied a various of arenes. In the case of using an indolizine and pentafluorobenzene, bis‐sulfidated product were obtained.

The reactions of tin(II) benzenethiolate and p-toluenethiolate with various fluoroaromatics in DMF have been studied. Replacement of some of the aromatic fluorines by the thiolate group was observed. The tin(II) aromatic thiolates are comparable in reactivity in these reactions with lead(II) benzenethiolate. All new compounds have been characterized by elemental analysis, and NMR (H-1 and F-19) and

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 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
