λ3-iodoarenes and λ3-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
混合的 λ 3 -碘代芳烃和具有 –OTf 配体的λ 3 -碘代芳烃都因其增强的反应性而备受追捧。在这里,我们描述了两种新的 ArI(OTf)(X) 物种的合成、反应性和综合表征,这是一类化合物,以前仅被用作反应性中间体,其中 X = Cl、F 及其与芳基底物的不同反应性。还描述了一种使用 Cl 2作为氯源和 ArI/HOTf 作为催化剂的用于失活芳烃亲电氯化的新催化系统。
