In this article, we have presented a novel, efficient and environmentally benign method for one-pot, one-step and odorless synthesis of a wide range of unsymmetrical sulfides from the reaction of aryl/benzyl/alkyl halides with aryl boronic acids in the presence of S8, NaOH and a catalytic amount of CuI in PEG200 as green solvent at 40–6 oC. The products were obtained in moderate to excellent yields. More importantly, this reaction is applicable for the gram-scale preparation of the desired sulfides.
