A transition metal/ligand-free disulfuration of anilines with disulfur transfer reagents (dithiosulfonate or tetrasulfide) is reported herein. The reaction, which can be considered as a reductive disulfuration variation of the classic Sandmeyer reaction, is performed under mild conditions and exhibits broad scope across the aniline substrate and disulfur transfer reagent classes. The gram-scale synthesis of disulfides is successfully achieved through this method, rendering the approach highly valuable.

苯胺的 Sandmeyer 型还原脱硫

本文报道了苯胺与二硫转移试剂（二硫代磺酸盐或四硫化物）的无过渡金属/配体二硫化。该反应可以被认为是经典 Sandmeyer 反应的还原二硫变化，在温和的条件下进行，并在苯胺底物和二硫转移试剂类别中表现出广泛的范围。通过这种方法成功地实现了二硫化物的克级合成，使该方法具有很高的价值。
