Herein, a novel and practical methodology for the photoinduceddecarboxylativedifluoroalkylation and perfluoroalkylation of α-fluoroacrylicacids is reported. A wide range of α-fluoroacrylicacids can be used as applicable feedstocks, allowing for rapid access to structurally important difluoroalkylated and polyfluoroalkylated monofluoroalkenes with high Z-stereoselectivity under mild conditions.
hydrogermanes. This methodology provides an efficient and robust approach for producing various germylated monofluoroalkenes with excellent stereoselectivity within a brief photoirradiation period. The feasibility of this reaction has been demonstrated through gram-scale reaction, conversion of germylated monofluoroalkenes, and modification of complex organic molecules.
