Kinetic study on the activation of PhICl₂ with Lewis bases for aromatic chlorination

<p dir="ltr">A study on the kinetics of the activation of PhICl₂ using catalytic chloride or pyridine in electrophilic chlorination of arenes has been carried out. The results indicate that both catalysts induce the release of Cl₂ from PhICl₂ and that the Cl₂ is the active reagent for chlorination in these reactions.</p>
