Sa a rive fasilman pa reyaksyon nan piridin ak sèl nitronium, tankou tetrafluoroborate nitronium. Ajan nitrat protetik tankou asid nitrique, nan kou, plon sèlman nan N-pwoton.

This occurs readily by reaction of pyridines with nitronium salts, such as nitronium tetrafluoroborate. Protic nitrating agents such as nitric acid, of course, lead exclusively to N-protonation.
