Abstract:

Over last few decades, organochalcogen (S, Se and Te) compounds have attracted important roles as reagents and synthetic intermediates in organic synthesis. Organodichalcogenides of sulfur, selenium or tellurium in counterpart of organic peroxides, play an important role in organochalcogen chemistry since they are stable, easy to handle, and reactive enough to produce eletrophilic, nucleophilic and radicophilic species. In addition showed important biological activities, such as antioxidants and antitumor. Recently we developed a new methodology to synthesis a wide range of organodiselenides and ditelurides, through cross-coupling reaction of selenium or tellurium and aryl halides using CuO nanopowder as catalyst. So we describe here an improved microwaveassisted method to prepare organodiselenides, ditelurides and disulfides using CuO nanoparticles as catalyst.
