application of copper ferrite nanoparticles (CuFe2O4) for one-pot odorless production of aryl alkyl thioethers using thiourea and alkyl bromides in wet polyethylene glycol as a green solvent. The catalyst was also successfully applied for one-pot synthesis of symmetrical diaryl trithiocarbonates via the reaction of sodium sulfide, carbon disulfide and aryl iodides under heterogeneous reaction condition.

在本文中,我们介绍了使用硫脲和烷基溴化物在湿聚乙二醇作为绿色溶剂的情况下,一锅无味地生产芳族烷基硫醚的铜铁氧体纳米粒子(CuFe 2 O 4)的催化应用。该催化剂也成功地用于一锅合成的对称二芳基三硫代碳酸酯经由异构反应条件下硫化钠,二硫化碳和芳基碘的反应 使用氯化铁(III)和氯化铜(II)合成磁性铜铁氧体纳米粒子,并使用XRD,FT-IR,AAS和TEM分析对其进行表征。使用简单的磁分离法将催化剂循环使用,并在碘苯,硫脲和苄基溴的反应中连续五次重复使用,而不会造成明显的活性损失。
