An expeditious, eco‐friendly, and efficacious protocol was achieved for the preparation of bis‐imidazoles and bis‐1,3‐thiazines from the reaction of tetracyanoethylene with dialdehydes or bis‐thiosemicarbazones, respectively. Merely mixing and sonicating the starting materials furnishes the desirable products in considerable yields. This reaction smoothly proceeded and presented many merits, over conventional
通过四氰基乙烯与二醛或双硫代半氨基咔唑的反应分别制备双咪唑和双1,3-噻嗪,该方法快速,环保且有效。仅将原料进行混合和超声处理就可以以可观的收率提供所需的产物。与常规方法和机械化学方法相比,该反应顺利进行并具有许多优点,包括简单的实验后处理程序,无副产物和较短的反应时间。此外,该协议在各种绿色指标上的得分令人钦佩,因此表明这些方法是理想的可持续性和绿色过程。
