A new and facile protocol for the synthesis of 2-amino-1,3,4-thiadiazoles in water is described. Reaction of acid hydrazides with easily prepared dithiocarbamates gives the corresponding thiadiazoles in moderate to excellent yields. 2-Amino-1,3,4-oxadiazoles were not observed as side products using this procedure.
描述了一种在水中合成2-氨基-1,3,4-噻二唑的新方法。酰肼与易于制备的二硫代氨基甲酸酯的反应以中等至优异的产率得到相应的噻二唑。使用该方法未观察到2-氨基-1,3,4-恶二唑为副产物。
