在130 ℃下，以5mol%MCM-41固载的双齿氮/CuCl配合物[MCM-41-2NeCuCl]为催化剂，Cs2 CO 3为碱，在纯水中进行了芳基碘与硫氰酸钾的多相碳硫键形成反应，得到了多种二芳基硫醚，产率中等至较高.这种多相铜催化剂可以很容易地通过简单的两步程序从市售和廉价的试剂制备，并通过简单的过滤回收，重复使用10个循环而不损失催化活性。(C)2013年爱思唯尔B。V.保留所有权利。
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.
