In this study, we developed mild conditions for the synthesis of an aryl thioether via aromatic substitution using aryl halides, which is a process that has rarely been studied. Aromatic substrates such as aryl fluorides activated with a halogen substituent are difficult to use for substitution reactions, but by using 18-crown-6-ether as an additive, these were successfully converted to their corresponding
在这项研究中,我们开发了使用芳基卤通过芳族取代合成芳基硫醚的温和条件,这是一个很少被研究的过程。芳香族底物如用卤素取代基活化的芳基氟化物很难用于取代反应,但通过使用18-冠-6-醚作为添加剂,这些被成功转化为相应的硫醚产物。在我们建立的条件下,除了多种硫醇外,毒性较小、无味的二硫化物也可以在0至25°C下直接用作亲核试剂。 全尺寸图像
