research of C-H bond hydroxylation, we found that multi-alkyl phenols could react with molecular oxygen under mild conditions. Herein, we describe an efficient oxidative de-aromatization of multi-alkyl phenols to p-quinols. 1 atm of molecular oxygen was used as the oxidant. Many multi-alkyl phenols could react smoothly at room temperature. Isotopic labeling experiment was also performed, and the result
对苯二酚是各种天然产物和药物化合物的普遍结构基序,是合成化学中的通用构建基块。报道的合成对-喹诺酚的方法需要化学计量的氧化剂。分子氧由于其天然,廉价和环境友好的特性而被认为是理想的氧化剂。在正在进行的CH键羟基化研究中,我们发现多烷基酚可以在温和的条件下与分子氧反应。在这里,我们描述了多烷基酚对p的有效氧化脱芳香化作用-喹诺醇。使用1atm的分子氧作为氧化剂。许多多烷基酚可以在室温下平稳反应。还进行了同位素标记实验,结果证明生成的羟基中的氧原子来自分子氧。
