Nickel‐Catalyzed Reductive Coupling for Transforming Unactivated Aryl Electrophiles into β‐Fluoroethylarenes. Issue 1 (10th December 2019) - Yang, Yi
Abstract: We report herein a facile synthetic method for converting unactivated (hetero)aryl electrophiles into β‐fluoroethylated (hetero)arenes via nickel‐catalyzed reductive cross‐couplings. This coupling reaction features the involvement of FCH2 CH2 radical intermediate rather than β‐fluoroethyl manganese species which provides effective solutions to the problematic β‐fluoride side eliminations. The practical value of this protocol is further demonstrated by the late‐stage modification of several complex ArCl or ArOH‐derived bioactive molecules.
