High‐Valent Copper Catalysis Enables Regioselective Fluoroarylation of Gem‐Difluorinated Cyclopropanes

Advanced Science
Transition‐metal (TM) catalyzed reaction of gem‐difluorinated cyclopropanes (gem‐DFCPs) has drawn much attention recently. The reaction generally occurs via the activation of the distal C─C bond in gem‐DFCPs by a low‐valent TM through oxidative addition,
