Highly regioselective ortho‐chlorination of phenols and phenol ethers can be achieved with a mixture of PhI(OTFA)2 and AlCl3 in moderate to good yields. The reproducibility of this method has also been demonstrated on gram‐scale. This new chlorinating reagent can be stored at least for two weeks at 4 °C without losing its reactivity.
用PhI(OTFA)2和AlCl 3的混合物可以实现中度到良好收率的苯酚和酚醚的高度区域选择性邻氯氯化。这种方法的重现性也在克级上得到了证明。这种新的氯化试剂可以在4°C下保存至少两周,而不会失去其反应活性。
