| Abstract: | Some analogies between organometallic chemistry and surface chemistry are developed. Comparison of Lewis acid promoted CO insertion and Zn2+ promotion of oxygenates in the hydroformylation of C2H4 over Rh, suggests that Zn2+ interaction with Rh-CO may promote migratory insertion which favors hydroformylation over hydrogenation of alkenes. CCO, which is observed in metal clusters should be a viable surface species. Finally, parallels can be found between the positioning of oxygen in clusters and on surfaces. |
