18F-Fluoroheteroarenes find wide application as radiotracers for PET (positronemissiontomography) imaging. Here, we present a deaminative radiosynthetic approach via pyridinium tetrafluoroborates that facilitates radiofluorination of 33 structurally diverse heteroarenes in up to 98 % RCY (radiochemical yield). This method was also amenable to automation and was successfully translated to an automated
