chemoselective hydroxylation. Interestingly, typical regiochemical scrambling associated with the C–H activation was further resolved by introducing a ligand-directed ortho hydroxylation of haloarenes and aryl methyl ethers.
我们在这里报告了一种便宜的乙酸铜(II)一水合物和吡啶配体对苯甲酰胺进行邻位C-H羟基化的实用方法。探索了分子内和分子间配体的组合以实现区域和化学选择性羟基化。有趣的是,通过引入卤代芳烃和芳基甲基醚的配体定向邻羟基化进一步解决了与C–H活化相关的典型区域化学加扰。
