The heterogeneous carbon-sulfur bond formation reaction of aryl iodides with potassium thiocyanate was achieved in neat water at 130 degrees C by using 5 mol% MCM-41-immobilized bidentate nitrogen/CuCl complex [MCM-41-2NeCuCl] as catalyst and Cs2CO3 as base, yielding a variety of diaryl sulfides in moderate to high yields. This heterogeneous copper catalyst can be easily prepared by a simple two-step procedure from commercially available and cheap reagents and recovered by a simple filtration and reused for 10 cycles without loss of catalytic activity.
