Cross-coupling between substrates that can be easily derived from phenols is highly attractive due to the abundance of phenols. Here, we report a dual nickel-/palladium-catalyzed reductive cross-coupling between aryl tosylates and aryl triflates; both substrates can be accessed in just one step from readily available phenols. The reaction has a broad functional group tolerance and substrate scope (>60
可以容易地衍生自苯酚的底物之间的交叉偶联由于苯酚的含量高而极具吸引力。在这里,我们报道了芳基甲苯磺酸盐和芳基三氟甲磺酸酯之间双重的镍/钯催化的还原交叉偶联。可以从一个容易获得的苯酚中仅一步之遥就获得两种底物。该反应具有宽泛的官能团耐受性和底物范围(> 60个实例)。此外,它显示出对空间效应的低敏感性,这是通过合成2,2'-二取代的联芳基和完全取代的芳基产物证明的。天然产品和药品中苯酚的广泛存在使简单的后期功能化成为可能,例如ezetimibe和酪氨酸。
