摘　　要：以四三苯基膦钯为催化剂,碳酸铯为碱,氯代碘苯和氯代苯硫酚在甲苯中加热到112℃回流16 h,发生偶联反应形成C—S—C硫醚键,合成了23个多氯代二苯硫醚系列化合物,产物均经IR,1H NMR表征,并测定熔点.反应操作简单,收率良好,条件温和,是一种较好的合成多氯代二苯硫醚化合物的新方法.Using tetrakis（triphenylphosphine）palladium as catalyst and cesium carbonate as base, chloroiodobenzenes were reacted under refluxing 16 h at 112℃ in toluene to synthesize 23 polychlorinated diphenyl sulfides. All the products were characterized by IR and 1H NMR spectra. The melting points of the products were also determined. The reaction processes have the advantages of simple work-up procedures, good yields and mild conditions. Thus this is a new and efficient method for the synthesis ofpolychlorinated diohenyl sulfide.
