A highly efficient and simple synthesis of unsymmetrical thioureas is reported based on the reaction of readily synthesized dithiocarbamates with amines, without using any catalyst under solvent-free conditions. The short reaction time, high yields, and solvent-free conditions are advantages of this method. We did not observe the formation of any symmetric disubstituted thiourea, under these reaction
据报道,基于容易合成的二硫代氨基甲酸酯与胺的反应,无需在无溶剂条件下使用任何催化剂,即可高效且简单地合成不对称硫脲。反应时间短,产率高和无溶剂条件是该方法的优点。在这些反应条件下,我们没有观察到任何对称的二取代硫脲的形成。
