A novel palladium(II)/copper(II)-catalyzed sulfidation of the C–H bond in electron-rich arenes and in pentafluorobenzene with disulfides was developed. This catalytic system can be used to efficiently produce various types of either unsymmetrical aryl sulfides or alkyl aryl sulfides. The present protocol could also be applied to the direct preparation of unsymmetrical aryl selenides via C–H selenation.

In this research, tetrafluorophenoxthiines were successfully synthesized from pentafluorobenzene and aryl thiols or diaryl disulfides in the presence of copper catalyst and ligand by using O2 as the oxidant, t-BuOLi as the base at 100 8C. The ligand (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one (L) played an indispensable role in the reaction. This work contains a notable mode of C-F bond activation, which is in the ortho position to the C-H bond of pentafluorobenzene.
Copper-catalyzed direct thiolation of pentafluorobenzene with diaryl disulfides or aryl thiols by C-H and C-F bond activation

experimental part, p. 1953 - 1959 (2012/05/05)
A Cu-catalyzed cross-coupling reaction of diaryl disulfides or aryl thiols 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 bisarylthiola
