glucose solution as reaction medium and catalyst underone-pot oxidant-free conditions. The desired products were obtained at 60 °C with good to excellent yields, and the reaction was performed chemoselectively without formation of 1,2-disubstitutedbenzimidazoles. No need for any extra oxidant, simple workup, and use of carbohydrates as fully green promoters are some advantages of the present work
摘要 以1 M葡萄糖溶液为反应介质和催化剂,在一锅无氧化剂条件下,进行了各种邻苯二胺与取代苯甲醛的反应。所需产物在 60 °C 下以良好到极好的收率获得,并且该反应通过化学选择性进行,没有形成 1,2-二取代苯并咪唑。不需要任何额外的氧化剂、简单的后处理以及使用碳水化合物作为完全绿色的促进剂是目前工作的一些优点。
