chitosan, a novel applicable matrix was successfully prepared and investigated as a heterogeneous nanocatalyst for preparing diaryl sulfides and aryl benzyl thioethers. The Cu(II)-his@CS nanocatalyst was characterized by FT-IR, CHN, XRD, FE-SEM, TEM, EDX, ICP-AES and TG analysis. This novel copper nanocatalyst was used for two and three component C–S coupling reactions of different aryl halides. The nanocatalyst
使用在组氨酸修饰的壳聚糖上固定的Cu 2+ NP反应,成功制备了新型适用基质,并作为制备二芳基硫醚和芳基苄基硫醚的多相纳米催化剂进行了研究。通过FT-IR,CHN,XRD,FE-SEM,TEM,EDX,ICP-AES和TG分析对Cu(II)-his @ CS纳米催化剂进行了表征。这种新颖的铜纳米催化剂用于不同芳基卤化物的两组分和三组分CS偶联反应。纳米催化剂在两个反应中均显示出高催化活性和可重复使用性。
