As a novel Sanger‐type reagent, 2‐fluoro‐5‐nitrophenyldiazonium tetrafluoroborate enabled the versatile functionalization of primary and secondary aliphatic alcohols. Based on a mild nucleophilic aromatic substitution of the fluorine atom under unprecedented, base‐free conditions, the diazonium unit on the aromatic core of the resulting aryl‐alkyl ether could be employed for such diverse transformations
作为一种新型桑格型试剂,2-氟-5-硝基苯基重氮四氟硼酸盐能够实现伯醇和仲脂肪醇的多功能官能化。基于在前所未有的无碱条件下氟原子的温和亲核芳族取代,所得芳基烷基醚芳族核心上的重氮单元可用于自由基 C−H 活化和环化等多种转化,如以及钯催化的交叉偶联反应。
