mechanism of SNAr reactions involving metal arene complexes is hypothesized to involve a stepwise pathway (addition followed by elimination), experimental data that support this hypothesis is still under exploration. Mechanistic studies and DFTcalculations suggest either a stepwise or stepwise-like energy profile. Notably, we isolated a rhodium η5-cyclohexadienyl complex intermediate with an sp3-hybridized
亲核芳香取代 (S N Ar) 是一种通过用亲核试剂取代离去基团将杂原子结合到芳香环中的强大策略,但这种方法仅限于缺电子芳烃。我们现在已经建立了一种通过催化 S N Ar 反应获取苯酚和苯基烷基醚的可靠方法。该方法适用于广泛的富电子和中性芳基氟化物,它们在经典的 S N Ar 条件下呈惰性。虽然 S N的机制假设涉及金属芳烃配合物的 Ar 反应涉及逐步途径(添加后消除),支持该假设的实验数据仍在探索中。机械研究和 DFT 计算表明了一个逐步或逐步的能量分布。值得注意的是,我们分离了铑 η 5 -环己二烯基复合中间体,其具有带有亲核试剂和离去基团的 sp 3 -杂化碳。
