Due to the aromatic character of the pyridine heterocycle, its basicity and the electron-attracting influence of the nitrogen atom, pyridinium salt is found to be of versatile chemical reactivities. Pyridinium cations can behave as electrophiles and 1,3-dipoles to take part in condensation, Michael addition, 1,3-dipolar addition, nuclear substitution and arrangement reactions, and find vast applications to organic syntheses.

Key words: pyridinium salt, organic synthesis, heterocycle, condensation, addition reaction, pyridine ylide
