thiolation of unprotected anilines with thiols for the synthesis of sulfide anilines has been described. The combinational use of I2 and DMSO played an important role to realize this kind of transformation without the aid of a metal catalyst and strong oxidants. The reaction selectivity was well controlled to provide mono-, bis-, and trisubstituted diaryl sulfide derivatives. More importantly, iodination
已经描述了碘促进的未保护苯胺与硫醇的发散硫醇化反应,用于合成硫化物苯胺。在不借助金属催化剂和强氧化剂的情况下,I 2和DMSO的组合使用对实现这种转化起了重要作用。很好地控制了反应的选择性,以提供单,双和三取代的二芳基硫醚衍生物。更重要的是,碘化和亚磺酰化可以同时发生,以提供有用的多官能化碘苯胺产物。该方法为在温和的反应条件下由C–H键构建C–S和C–I键提供了有效的方案。
