Regioselective Oxidative Chlorination of Arenols Using NaCl and Oxone

摘要

We developed a practical and environmentally benign method for the chlorinative dearomatization of arenols using transient electrophilic chlorinating species generated in situ from inexpensive sodium chloride and Oxone as a Cl source and oxidant, respectively, under mild conditions. Moreover, the regioselective chlorination or chlorinative dearomatization of 1- naphthols was also achieved by changing the reaction conditions.
