Fluorinated heterocycles are prevalent in pharmaceuticals, agrochems., and materials. However, reactions that incorporate fluorine into heteroarenes are limited in scope and can be hazardous. The authors present a broadly applicable and safe method for the site-selective fluorination of a single carbon-hydrogen bond in pyridines and diazines using com. available silver(II) fluoride. The reactions occur at ambient temperature within 1 h with exclusive selectivity for fluorination adjacent to nitrogen. The mild conditions allow access to fluorinated derivatives of medicinally important compounds, as well as a range of 2-substituted pyridines prepared by subsequent nucleophilic displacement of fluoride. Mechanistic studies demonstrate that the pathway of a classic pyridine amination can be adapted for selective fluorination of a broad range of nitrogen heterocycles.
