  • Copper-catalyzed one-pot synthesis of benzimidazole derivatives

    A simple, efficient, and environmentally benign method has been developed for the synthesis of 2-substituted benzimidazoles through a one-pot reaction of phenylenediamines with aryl aldehydes in excellent isolated yields under mild conditions using Cu(II) complex as the selective, recyclable, and heterogeneous catalyst at ambient temperature. The Cu(II) complex as a heterogeneous catalyst can be reused in further catalytic reactions, and it was found that its activity remained largely unchanged for eight successive runs. No metal-complex leaching was observed after the consecutive catalytic reactions. The salient features of this method include mild conditions, high yields, simple procedure, and good recovery and reusability of the heterogeneous catalyst.Key words: benzimidazole, o-phenylenediamine, arylaldehydes, heterogeneous catalyst, N,N-bis (2-hydroxyphenyl)pyridine-2,6-dicarboxamide.

    以 Cu(II) 复合物为选择性、可回收的异相催化剂,在温和条件下通过苯二胺与芳基醛的一锅反应合成 2-取代的苯并咪唑,并获得了极好的分离产率。作为一种异相催化剂,Cu(II)络合物可在进一步的催化反应中重复使用,而且研究发现其活性在连续运行八次后基本保持不变。在连续进行催化反应后,没有观察到金属络合物浸出现象。该方法的突出特点是条件温和、产率高、操作简单、异相催化剂的回收率和重复利用率高。 关键词:苯并咪唑、邻苯二胺、芳基醛、异相催化剂、N,N-双(2-羟基苯基)吡啶-2,6-二甲酰胺。
