A new and facile protocol for the synthesis of dithiocarabamate in EtOH/$H_2O$ is described. Reaction of aromatic and aliphatic amines with $CS_2$ and 3,4-dihydro-2H-pyran in the presence of N,N,N',N'-tetrabromobenzene-1,3-disulfonamide [TBBDA] and poly(N-bromo-N-ethylbenzene-1,3-disulfonamide) [PBBS] gives the corresponding dithiocarbamates in good to high yields.
介绍了在 EtOH/$H_2O$ 溶液中合成二硫代氨基甲酸酯的一种新的简便方法。在 N,N,N',N'-四溴苯-1,3-二磺酰胺 [TBBDA] 和聚(N-溴-N-乙基苯-1,3-二磺酰胺)[PBBS] 存在下,芳香族和脂肪族胺与 $CS_2$ 和 3,4-二氢-2H-吡喃发生反应,以良好至高产率得到相应的二硫代氨基甲酸酯。
