Production of carbon-sulfur bond is one of the most important chemical reactions due to the great applicant in organic synthesis,1 professional pharmacy as drugs for the treatment of diseases such as, Parkinson, Alzheimer, Diabetes, Cancer, HIV, Immune and Inflammatory diseases, and in material sciences. Cross-coupling reactions of aryl halides with thiols are one of the most synthetic methods for the synthesis of sulfides. Very recently, we have reported a novel method for one-pot odorless C-S-C bonds formation using phenyl boronic acid, sulfur powder and aryl/benzyl halides. Although this protocol represent considerable progress, however separation, recover and reuse of catalyst are difficult. Moreover recently Iranpoor and co-workers using triphenyltin chloride as a source of phenyl group. In this research for the first time Cu(II)ZSM-5 and Cu(I)ZSM-5 as heterogeneous, recoverable and recyclable nanocatalysts used for the synthesis of phenyl aryl sulfides and biaryl sulfides from reaction of triphenyltin chloride or phenyl boronic acid as a phenyl source,with aryl/benzyl halides in the presence of S8 as sulfur source and base in DMF 80 oC In conclusion, these mothode have several advantages such as air-stable, inexpensive, reusable, easily made and nano-scale size. The reaction using the catalyst exhibited good yield.
