摘要：

A highly efficient and ligand-free copper(I) sulfide catalyzed cross-coupling reaction of aryl iodides with diaryl disulfides was developed. With only 1 mol-% of Cu2S as the catalyst, iron powder as the reductant, and K2CO3 as the base, aryl iodides reacted with disulfides in DMSO at 90-110 degrees C for 18 24 h under an atmosphere of argon to give the corresponding aryl sulfides in good to excellent yields. In addition, the catalyst is recyclable and reusable with some loss of activity.
