Acetoxylation of arenes is an important reaction and an unmet need in chemistry. We report a metal-free, direct acetoxylation reaction using sodium nitrate under an anhydrous environment of trifluoroacetic acid, acetic acid, and acetic anhydride. Arenes (31 examples), with oxidation potentials (Eox, in V vs SCE) lower than benzene (2.48 V), were acetoxylated with good yields and regioselectivity. A
芳烃的乙酰氧基化是一个重要的反应,也是化学中未满足的需求。我们报告了在三氟乙酸、乙酸和乙酸酐的无水环境下使用硝酸钠进行的无金属直接乙酰氧基化反应。芳烃(31 个实例)的氧化电位(E ox,单位为 V vs SCE)低于苯(2.48 V),以良好的产率和区域选择性被乙酰氧基化。提出了一种逐步的单电子转移机制。
