A simple, efficient and environmentally friendly method for iron or boron-catalyzed C-H arylthiation of substituted phenols at room temperature has been developed, and the corresponding diaryl sulfides were prepared in good to excellent yields. The protocol uses readily available 1-(substituted phenylthio)pyrrolidine-2,5-diones as the arylthiation reagents and inexpensive and environmentally friendly FeCl3 or BF3·OEt2 as the catalyst, moreover no ligands, additives or extrusion of air are required, and the reactions can be performed successfully at room temperature.
已开发出一种简单、高效且环境友好的方法，用于在室温下铁或硼催化取代苯酚的C-H芳基硫醚化反应，并以良好至优异的产率制备相应的二芳基硫醚。该方法使用易于获得的1-（取代苯硫基）吡咯烷-2,5-二酮作为芳基硫醚化试剂，以及廉价且环境友好的FeCl3或BF3·OEt2作为催化剂，此外无需配体、添加剂或排除空气，并且反应可以在室温下成功进行。
