Multi-Substituted Trifluoromethyl Alkene Construction via Gold-Catalyzed Fluoroarylation of gem-Difluoroallenes

An unprecedented fluoroarylation of 1,1-difluoroallenes with cost-effective nucleophilic fluoride reagent and aryldiazonium salts is reported. This visible light promoted gold-catalyzed reaction allows a stereo- and regioselective incorporation of both fluorine...
