The mechanism of the dehydrogenation of methylcyclohexane (MCH) on Pt(111) has been studied using HREELS, TPD, and BPTDS. Upon warming a monolayer of MCH closed at 100 K, 55% desorbs and 45% dehydrogenates to a {pi}-allylic species at 240 K. This {pi}-allylic intermediate dehydrogenates further to a benzyl species at 310 K. Adsorbed benzyl is stable up to 50 K on Pt(111), but at higher temperatures further hydrogenation occurs. 27 refs., 6 figs.
