Formal meta-C–H-Fluorination of Pyridines and Isoquinolines through Dearomatized Oxazinopyridine Intermediates

Organofluorine compounds, including fluorinated pyridines and isoquinolines, play a crucial role in pharmaceuticals, agrochemicals, and materials science. However, step-economic selective C-H-functionalization to access these fluorinated azaarenes is still underexplored, with selective
