A selectivity-driven catalyst design approach was adopted to address chemoselectivity issues in the oxidative coupling of phenols. This approach was utilized for developing a Co(II)[salen]-catalyzed aerobic oxidative cross-coupling of phenols in a recyclable 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) solvent. The waste-free conditions offer a sustainable entry to nonsymmetric biphenols via a mechanistic
采用选择性驱动的催化剂设计方法来解决酚氧化偶联中的化学选择性问题。该方法用于开发可回收的1,1,1,3,3,3-六氟丙烷-2-醇(HFIP)溶剂中的Co(II)[salen]催化的苯酚的好氧氧化交叉偶联。无浪费条件通过一种机械方案使非对称双酚可持续进入,该方案涉及将游离的苯氧基与连接的2-萘氧基偶联。
