Abstract
A method for stereoselective construction of Z-monofluoroalkenes by nickel-catalyzed defluorinative coupling of gem‑difluoroalkenes in mild conditions was described. The combination of lithium organoborate and ZnBr2 generated in situ lithium aryl zincates, which facilitates the transmetalation step of the nickel-catalyzed cross coupling reaction.
