heterogeneous catalyst was characterized by FT-IR, 13C NMR, XRD, SEM, EDX, BET, BJH, and ICP-AES analysis. The catalytic activity of the catalyst was probed through the Ullmann reaction for synthesis of diaryl ether derivatives from two component reactions of aromatic arylhalides and phenol derivatives in DMSO. Simple procedure, high yields, short reaction time, and environmentally benign methods are advantages
摘要 Cu基于5,5'-双四唑([Cu 2 BT·2H 2 O] n)作为可回收的金属有机骨架(MOF)多相催化剂通过FT-IR、13 C NMR、XRD、SEM、EDX、 BET、BJH 和 ICP-AES 分析。该催化剂的催化活性是通过乌尔曼反应从芳香芳基卤化物和苯酚衍生物在 DMSO 中的两组分反应合成二芳基醚衍生物来探测的。该协议的优点是程序简单、产量高、反应时间短和环境友好。催化剂很容易通过简单的过滤分离并可重复使用,而不会显着降低其催化效率。
