主要內容:

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 reactions are illustrative consequences of this altered reactivity.  This lecture focuses on the 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 d0 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” oxide surfaces, and the broad scope of their catalytic properties, 4) Unusual catalytic chemistry of group 6 dioxo complexes adsorbed on activated 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, including the catalytic detoxification of gasoline, stereoselective aromatics hydrogenation, biofeedstock trans-esterification, and bio-alcohol dehydrogenation.
