A Bi(OTf)-catalyzed oxidative cross-coupling reaction of 3-hydroxycarbazoles with arenols was developed under mild conditions. Both substrates were used in a 1:1 molar ratio in the presence of a catalytic amount of Bi(OTf). The reaction was carried out under an oxygen atmosphere at 30 °C to afford -symmetric hydroxybiaryls in good yields (up to 94%) with high chemo- and regioselectivity.
在温和条件下开发了一种Bi(OTf)催化的3-羟基咔唑与芳醇的氧化交叉偶联反应。在催化量的Bi(OTf)存在下，两种底物以1:1的摩尔比使用。该反应在氧气气氛下于30℃进行，以高化学选择性和区域选择性，高产率（高达94%）得到对称的羟基联芳基化合物。
