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. With tetrakistriphenylphosphine palladium as catalyst, cesium carbonate as a base, chloroiodinated benzene and chlorothiophenol were heated to 112 ° C for 16 h in toluene to form C-S-C thioether bond by coupling reaction, Twenty-three polychlorinated diphenyl sulfide compounds were synthesized and the products were characterized by IR and 1H NMR and the melting point was determined.The reaction was simple, the yield was good, the conditions were mild, and it was a good synthetic polychlorinated dibenzene A new method of sulfide compounds.
