We report a zinc catalyst for propene hydrogenation and propane dehydrogenation.  This highly selective catalyst operates through a Lewis Acid mechanism rather than a metal-centered redox pathway. Furthermore, it is long-lived, demonstrating catalytic activity for > 12 hours and near 100% selectivity for propane dehydrogenation to propene at 550 °C.
