  Interaction of gaseous D atoms with alkyl halides adsorbed on Pt(111), H/Pt(111), and C/Pt(111) surfaces: Hot-atom and Eley–Rideal reactions. III. Isopropyl iodide

  摘要：

  The kinetics of reactions of D atoms with isopropyl iodide adsorbed on Pt(111), H covered Pt(111), and monolayer C covered Pt(111) surfaces were studied using direct product detection. Propane, C3H7D, was observed as gaseous product formed through propyl abstraction from the halide. At low temperatures, below the propane desorption temperature, and submonolayer coverages the reaction products remain adsorbed on the surface. At higher temperatures (coverages) they desorb. With C/Pt(111) as substrate, the reaction kinetics are compatible with the operation of an Eley–Rideal mechanism. On Pt(111) and H/Pt(111) substrates the abstraction kinetics of propyl from the halide is controlled by hot-atom mechanisms. Coadsorbed H leads to simultaneous abstraction of H from the surface towards HD and H2, as well as to a gaseous C3H8 product. Propyl abstraction cross-sections are in the range 0.5 to 1.5 Å2, in line with direct processes. The results confirm the role of a metallic or nonmetallic substrate on the mechanisms of atom–adsorbate reactions.

  exchange follows the Olah σ-basicity concept: tertiary>secondary>primary C–H bonds independently of the further reactivity of these bonds. At higher concentrations of SbF5 the exchange process gives way to increasing ionization of the alkane, first via protolysis and later via an oxidative process with concomitant reduction of SbF5.
