Abstract
A new cobalt-catalyzed coupling of aryl halides with thiophenols and alkanethiols is reported. A variety of aryl sulfides can be prepared in excellent yields under mild reaction conditions using 1-2 mol % of CoI2(dppe) and Zn. This new cobalt-catalyzed coupling represents an interesting addition to previously known methods to synthesize thioethers. [reaction: see text].
摘要
报道了一种新型的钴催化芳基卤化物与苯硫酚和链烷硫醇的偶联反应。在温和的反应条件下，使用1 - 2 mol%的CoI₂(dppe)和锌，可以以优异的产率制备多种芳基硫醚。这种新型的钴催化偶联反应是对先前已知的硫醚合成方法的一个有趣补充。[反应：见正文]
