reaction catalyzed by NiCl2, phenyldithiocarbamates react with iodobenzenes to give diaryl sulfides smoothly and in good to excellent yields (66–93 %). The catalyst is cheap, the reaction is easy to carry out, the substrate scope is broad, and the yields are good. Thus, this gives an alternative way to prepare diaryl sulfides.
在NiCl 2催化的反应中,苯基二硫代氨基甲酸酯与碘苯反应生成顺丁二硫醚,收率良好至优异(66-93%)。该催化剂价格便宜,反应容易进行,底物范围广,收率好。因此,这提供了制备二芳基硫化物的替代方法。
