Li, Wangbing; Lu, Zhichao; Hammond, Gerald B.; Xu, Bo published their research in Organic Letters in 2021. The article was titled 《Unbalanced-Ion-Pair-Catalyzed Nucleophilic Fluorination Using Potassium Fluoride》.Electric Literature of C9H9BrO2 The article contains the following contents:
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 part of the paper was very detailed, including the reaction process of Benzyl 2-bromoacetate(cas: 5437-45-6Electric Literature of C9H9BrO2)
Benzyl 2-bromoacetate(cas: 5437-45-6) belongs to benzyl acetate. Benzyl acetate is a synthetic chemical produced for industry from benzyl alcohol and acetic acid, but is also naturally present in the essential oils of many plants, including jasmine and ylang ylang.Electric Literature of C9H9BrO2
