continuous‐flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three‐step metalation, zincation, and Negishi cross‐coupling sequence, providing efficient access to a variety of functionalized 2‐fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous‐flow technology
