One of the important examples of modern synthetic method is the chemistry that helps formation a new bond between two atoms in the process. The construction of carbon-sulfur bond is one of the most important chemical reactions due to the great applicant in organic synthesis, pharmaceutical industry, and in material sciences. The main synthetic method for the preparation of these valuable materials involves the cross-coupling of aryl halides with thiols in the presence of transition metals catalysts. We report herein for the first time the use of triphenyltin chlorid or phenyl boronic acid as phenyl sources, and combined with S8, a commercially available, cheap, chemical stable, odorless and green sulfur source, as a thiolating agent in reaction with aryl halides for the synthesis of sulfides catalyzed by CuFe2O4 MNPs Firstly, magnetic copper ferrite nanoparticles CuFe2O4 (MNPs) was synthesized by modified methods and characterized by SEM, EDX, XRD, AGFM and FT-IR techniques and then these heterogeneous, recoverable and recyclable nanocatalysts were used for the synthesis of sulfides in good to high yields under mild reaction conditions. This nanocatalyst is air-stable, easily made, low cost and nano-scale size create a large surface area to volume ratio and even in the presence of sensitive substituents, the reaction proceeds successfully to provide the favorite products in high yields without change in other functional groups.
