Highly regioselective ortho‐chlorination of phenols and phenolethers 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.

4b, 5a, 5b, 5c, 5d and 5e. Some of them are described for the first time. By using semiempirical PM3 method theoretical substituent effects on the chlorinating reaction are calculated. A chlorination mechanism of carbazoles and N-substituted carbazoles are compared.
