中文摘要：

以聚乙二醇-600为反应介质，在CuSO4/葡萄糖催化作用下，取代苯胺与硫脲有效缩合生成了一系列相应的苯基硫脲。反应产物经水洗、过滤、乙醇/水中重结晶即可获得。该方法不使用有毒有机溶剂，原料及催化剂价廉，后处理简单便捷，因此是合成该类化合物高效绿色的新方法。所有产物经熔点、红外、核磁共振氢谱进行了表征。

英文摘要：

A series of diphenylthioureas were efficiently synthesized through condensation of anilines with thiourea catalyzed by Cu-SO4/glucose in PEG-600. The products were obtained just by washing with water, filtration and recrystallization from EtOH/H2 O. The present method exhibited the following advantages：free use of toxic organic solvent,cheap starting materials and catalyst, and simple work-up procedure. These merits made it an efficient and green alternative to synthesis of diphenylthioureas. All the products were characterized with m. p. ,IR and 1 H-NMR analysis.
