On December 17, 2021, Li, Wangbing; Lu, Zhichao; Hammond, Gerald B.; Xu, Bo published an article.Electric Literature of 2567-29-5 The title of the article was Unbalanced-Ion-Pair-Catalyzed Nucleophilic Fluorination Using Potassium Fluoride. And the article contained the following:
An unbalanced ion pair promoter (e.g., tetrabutylammonium sulfate), consisting of a bulky and charge-delocalized cation and a small and charge-localized anion, greatly accelerated nucleophilic fluorinations using easy handling KF. An inexpensive and com. available ion-exchange resin was successfully converted to the polymer-supported ion pair promoter (A26-SO42-), which could be reused after filtration. Moreover, A26-SO42- could be used in continuous flow conditions. Water was well-tolerated. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Electric Literature of 2567-29-5
