construction of diaryl sulfides through the cross‐coupling of aryl iodides and thiols in microwave heating is described. By using this method, a variety of diaryl sulfides can be prepared in a mild condition and in high yields. Deactivated 4‐nitrothiophenol was effective to afford the product in 94% yield. Sterically hindered ortho‐substituted aryl iodides or thiophenols provided diaryl sulfides effectively

aryl halide (1 equiv.) in 2propanol at 120 °C for three hours in the presence of K2CO3 (2 equiv.) as base usingcopper(I) iodide as catalyst (5 mol%) and trans-cyclohexane-1,2-diol (2 equiv.) as ligand provides a rapid and convenient method for C−Sbondformation. The process is most efficient using thiophenol and aryl iodide precursors, both of which may contain electron-donating and electronwithdrawing
A novel synthesis of unsymmetrical aryl sulfides, which requires no transition metal catalyst and no oxidant, was developed. This base-promoted cross-coupling reaction proceeded using arylhydrazines and 1 equiv amount of disulfides under inert gas conditions to afford the unsymmetrical aryl sulfides in good yields.
