| Outline of Final Research Achievements |
Mechanistic study on the surface chemistry of rhenium-catalyzed heterogeneous metathesis reaction was investigated. First, metathesis reaction of 1-octene has been carried out to evaluate the effect of Lewis acid modification of methyltrioxorhenium (MTO) catalyst, using γ-alumina (γ-Al2O3) as a catalyst support. As a result, ZnCl2-modified γ-Al2O3 was found to exhibit the highest catalytic activity towards the metathesis reaction. To further understand the mechanism of active species formation in the reaction, 13C-labeled MTO was synthesized, and several different catalyst samples were subjected for the mechanistic study using 13C CP-MAS NMR measurement. From this study, chemical structures of rhenium catalysts that were chemically bonded to the surface of mesoporous alumina have been found.
