Novel CuO on mesoporous silica is prepared under a convenient approach, and has been shown to be an efficient catalyst for cross-coupling reactions of thiols with aryl iodides with only 1.0–5.0 mol% catalyst loading.

Transition metal catalyzed coupling of thiols with aryl iodide offers a convenient method for accessing C–S linkage in organic synthesis. Herein, we report an efficient and practical method for the C–Scrosscoupling of thiophenols with aryl iodides using a Cu(I) catalyst. A diverse set of thiophenols is coupled with electron rich and poor aryl iodides to obtain diaryl sulfides in good to excellent

Thioethers can be efficiently prepared via palladium-catalysed cross-coupling of arene- or heteroarene thiols with arene- or heteroarene iodides. A simple, cheap and robust catalytic system is described that couples a broad range of electron-deficient as well as electron-rich substrates in high yield. (C) 2001 Elsevier Science Ltd.

A convenient and metal-free protocol for the synthesis of 2-arylthio(seleno)imidazoles from imidazoles and disulfides (diselenides) was developed through the direct thiolation (selenylation) of imidazoles promoted by 0.5 equiv. of iodine. This process is scalable and tolerates a wide spectrum of disulfides (diselenides) to deliver products in high yields. Compared with previous methods, this protocol
