Webwe next tested its efficacy in activating PhICl2 in the chlorination of anisole. Addition of 20% pyridinium chloride to PhICl2 and anisole resulted in a conversion of 92% at t = 60 minutes, higher than what was seen with pyridine. This observation led to the hypothesis that the activating agent is either pyridinium or chloride anions ... WebAbstract A study on the potential activating role of pyridine in the electrophilic chlorination of anisole by PhICl 2 has led to the discovery that soluble sources of chloride ions activate PhICl 2 in the reaction at catalytic loadings, greatly increasing the rate of chlorination.
