We report a fast, efficient, and metal-free protocol for the synthesis of unsymmetrical biaryl sulfides and aryl–alkyl sulfides (4-methoxy-2-sulfanyl-phenylcarbamates) under catalytic influence of 2,4-dinitrobenzoic acid. The reaction proceeded in a regioselective anti-Michael addition fashion and all the products were obtained within a very short period of time and in good to excellent yields.
我们报告了一种在 2,4-二硝基苯甲酸催化作用下合成不对称联芳基硫化物和芳基-烷基硫化物(4-甲氧基-2-硫烷基-苯基氨基甲酸酯)的快速、高效和无金属的方案。反应以区域选择性抗迈克尔加成方式进行,所有产物都在很短的时间内获得,产率良好至极好。
