In the presence of phosphazene P2-Et base as well as 1,8- diazabicyclo[5.4.0]undec-7-ene (DBU) the coupling of aryl iodides with arenethiois only requires catalytic amounts of CuBr. Under these conditions the reaction can be performed in refluxing toluene to give biaryl thioethers in excellent yields. (C) 2000 Elsevier Science Ltd.
