A tetrabutylammonium iodide-mediated direct sulfenylation of arenes with ethyl arylsulfinates in water was developed. Various electron-rich arenes and ethyl arylsulfinates were investigated in the reaction, and a series of aryl sulfides were obtained in excellent yields. The advantages of this green protocol were simple reaction conditions (metal-free, water as the solvent, and under air), odorless and easily available sulfur reagent, broad substrate scope, and gram-scale synthesis. Moreover, the potential application of aryl sulfides was exemplified by further transformations.

芳基亚磺酸乙酯在水中的芳烃磺化反应。

研制了碘化四丁铵介导的芳基亚磺酸乙酯在水中的芳烃直接亚磺基化反应。在反应中研究了各种富电子芳烃和芳基亚磺酸乙酯，并以优异的收率获得了一系列芳基硫醚。这种绿色方案的优点是反应条件简单（无金属，以水为溶剂，在空气中），无味且易获得的硫试剂，广泛的底物范围和克级合成。而且，芳基硫化物的潜在应用通过进一步的转化来举例说明。
