Pyridine features prominently in pharmaceuticals and drug leads, and methods to selectively manipulate pyridine basicity or metabolic stability are highly sought after. A robust, metal‐free direct fluorination of unactivated pyridylic C−H bonds was developed. This convenient reaction shows high functional‐group tolerance and offers complimentary selectivity to existing C−H fluorination strategies.
