The reaction of Mannich bases derived from ortho-hydroxyacetophenones with N,N-dialkyldithiocarbamic acid salts result in the formation of the corresponding dithiocarbamic acid esters via an amine moiety replacement when the process is conducted in cold water. Attempts to carry out the synthesis in refluxing ethanol-water mixture led to the insertion of carbon sulfide at the C—N bond in Mannich bases
当该过程在冷水中进行时,衍生自邻羟基苯乙酮的曼尼希碱与 N,N-二烷基二硫代氨基甲酸盐的反应导致通过胺部分置换形成相应的二硫代氨基甲酸酯。在回流的乙醇-水混合物中进行合成的尝试导致在曼尼希碱的 CN 键处插入硫化碳。N-芳基二硫代氨基甲酸盐与上述曼尼希碱反应仅得到双-(2-(2-羟基苯甲酰基)乙基)硫醚。
