Surface Science Meets Homogeneous Catalysis

When chemisorbed upon certain surfaces, the reactivity of many types of organometallic molecules is dramatically enhanced in ways that historically have been poorly understood.  High activities for a variety of catalytic olefin reactions are illustrative consequences of this altered reactivity.  This lecture focuses on intricate non-covalent and covalent multi-center interactions that modulate these catalytic processes, focusing primarily on polymerization and hydrogenation/dehydrogenation processes.  Specific interrelated topics include: 1) Catalytic chemistry of mononuclear and multinuclear  catalysts anchored on/activated by surfaces versus those in homogeneous solution, 2) Catalytic chemistry and cooperativity effects in multinuclear groups 4 and 6 catalysts in homogeneous solution, 3) Definitive structural characterization of these catalysts on “super-acidic” surfaces, and the scope of their catalytic properties, 4) Unusual catalytic chemistry of group 6 dioxo complexes on carbon surfaces.  It will be seen that the information obtained from these studies leads to design rules for next-generation homogeneous and supported catalysts, and for novel and useful polymerization and hydrogenation/-dehydrogenation processes, such as the catalytic detoxification of gasoline and bio-alcohol dehydrogenation.
