Both mixed λ-iodoarenes and λ-iodoarenes possessing -OTf ligands are coveted for their enhanced reactivities. Here we describe the synthesis, reactivity, and comprehensive characterisation of two new ArI(OTf)(X) species, a class of compound that were previously only invoked as reactive intermediates where X = Cl, F and their divergent reactivity with aryl substrates. A new catalytic system for electrophilic chlorination of deactivated arenes using Cl as the chlorine source and ArI/HOTf as the catalyst is also described.
混合的λ-碘芳烃和带有-OTf配体的λ-碘芳烃因其增强的反应活性而备受青睐。在此，我们描述了两种新型ArI(OTf)(X)物种的合成、反应活性及全面表征，这类化合物此前仅作为反应中间体被提及，其中X = Cl、F，以及它们与芳基底物的不同反应活性。还描述了一种以Cl为氯源、ArI/HOTf为催化剂用于钝化芳烃亲电氯化的新催化体系。
