synthesis of thioethers by forging C(aryl)-S bond via an aryne mechanism. The active aryne species can be generated from o-diiodoarenes and NaH in THF at room temperature, then lead to the arylations of a wide range of aryl thiols and thioureas. Different from transition metal-catalyzed cross-couplingreactions, no disubstituted byproduct is formed in our protocol. The o-iodoaryl thioether products are
在此,我们报道了一种通过芳基机理形成 C(芳基)-S 键来合成硫醚的方法。室温下,邻二碘芳烃和 NaH 在 THF 中可以生成活性芳炔,然后导致多种芳基硫醇和硫脲的芳基化。与过渡金属催化的交叉偶联反应不同,我们的方案中没有形成双取代的副产物。邻碘芳基硫醚产品是可以转化为药学上感兴趣的分子的中间体。
