The nucleophilic aromatic substitution reactions of piperidine with N-methylpyridinium ions in methanol occur via rate determining preassociation of a second piperidine molecule with the addition intermediate followed by barrier-free deprotonation. Loss of leaving group is concurrent with deprotonation for Cl, Br, and I (E2), but subsequent to deprotonation, although rapid, for CN and F (E1cBIRR).
