presence of other functional groups. Existing methods for the activation of tertiary aliphaticfluorides involve stoichiometric abstraction with fluorophilic Lewis acids or by Lewis-acid-catalyzed trapping with Si reagents. Herein, we describe a B(C6F5)3·H2O-catalyzed Friedel–Crafts reaction of tertiary alkyl fluorides that proceeds rapidly at room temperature without trapping reagents. The method is
C–F键是与碳最强的单键,构成存在其他官能团时选择性催化活化的固有挑战。现有的用于活化叔脂肪族氟化物的方法包括用亲氟路易斯酸或通过路易斯酸催化的硅试剂捕集的化学计量萃取。本文中,我们描述了叔烷基氟的B(C 6 F 5)3 ·H 2 O催化的Friedel-Crafts反应,该反应在室温下快速进行而没有捕获试剂。该方法适用于F完全选择性-在传统上更好的离去基团和显示器的自催化动力学特征。
