One-pot synthesis of 2-arylphenols starting from 2-iodo-2-cyclohexen-1-one and arylboronic acids through sequential Suzuki–Miyaura coupling/dehydrogenative aromatization with Pd/C catalysis has been developed. A range of arylboronic acids serve as substrates, including those containing electron-donating or electron-withdrawing groups. Additionally, one-pot synthesis of di- or trisubstituted phenols
已经开发了以 2-iodo-2-cyclohexen-1-one 和芳基硼酸为原料,通过 Suzuki-Miyaura 偶联/脱氢芳构化和 Pd/C 催化的一锅法合成 2-芳基苯酚。一系列芳基硼酸可用作底物,包括含有给电子或吸电子基团的那些。此外,通过使用 2-iodo-2-cyclohexen-1-one 衍生物作为底物,还可以一锅法合成在邻位带有苯基的二或三取代苯酚。在本方法中,使用市售且易于去除的 Pd/C 作为催化剂,没有任何配体。使用操作简单的程序和可及的条件以中等至高产率提供改性苯酚作为唯一产品。
