The oxidations of pentan‐1‐ol with 12 dichromates, fluorochromates, chlorochromates and bromochromate of heterocyclic bases in acidic medium exhibit identical kinetic behavior; first order each with respect to the chromium(VI) reagents and alcohol, and are acid catalyzed. The Arrhenius plots show two common points of intersection, one by the three quinolinium complexes and the other by the rest, suggesting the involvement of the quinolinium moiety in the transition state to be different from that of the other heterocyclic bases.
