Model organometallic complexes provide a useful analogy to metal catalyst surfaces. Their similarities to a supported metal, absorbate atoms, and metal-absorbate bonds allow comparison of surface chemistry studies. By probing the nature and mechanisms of intermediate surface chemistry species, catalyst activity and selectivity effects can be understood. Chemical trapping identifies surface species through the use of a trapping reagent, such as (CH sub 3 ) sub 2 SO sub 4 , which theoretically deposits an alkyl group onto the surface species at the species' previous place of attachment to the surface. Chemical trapping is here importantly extended to a model organometallic complex, namely, ethylidyne tricobalt enneacarbonyl, to enjoy the mechanism-hunting advantages from a well-defined metal-absorbate complex system. 8 refs., 4 figs., 3 tabs.
