A novel and solvent-free protocol for the synthesis of diarylsulfides by the copper-catalyzed oxidative S-arylation of 1,2-diaryldisulfides with aryltrimethoxysilanes is reported. In the presence of CuI, 2-(di-tert-butylphosphino)biphenyl, and TBAF (n-Bu

The direct thiolation of phenylpyrazole with disulfide using the FeBr 3/I2 complex as the catalyst in MeCN at 80 °C was reported. With the optimum conditions, several fipronil derivatives of 4-sulfenylpyrazole were synthesized by the reaction of 5-amino-1-[2,6-dichloro- 4-(trifluoromethyl)phenyl-lH-pyrazole-3-arbonitrile (1a) with disulfides (2) in moderate to good yields. The coupling reaction with diaryl diselane also occurred under similar conditions.
