The kinetic isotope effect and the lack of deuterium-hydrogen exchange in the unconverted reactants show that chemisorption of the reactant is the slow step of the dehydrocyclization mechanism with a Pt-SiO 2 catalyst. While the chemisorption was nearly irreversible for a Pt-SiO 2 catalyst, this was
