| Abstract: | A triruthenium ketenylidene cluster PPN]2Ru3(CO)9(CCO)] was deposited on MgO, SiO2, and SiO2-Al2O3, and the nature of surface species on the oxides were studied by an IR spectroscopic study along with catalytic performances in13CO exchange reaction and hydroformylation of ethylene. The IR study suggested the stoichiometric protonation of Ru3(CO)9(CCO)]2-with surface hydroxyl groups on SiO2 and SiO2-Al2O3 to give HRu3(CO)9(CCO)]– and H2Ru3(CO)9(CCO), respectively. H2Ru3(CO)9(CCO)/SiO2– Al2O3 was active for13CO exchange reaction, while Ru3(CO)9(CCO)]2–/MgO showed high activity and selectivity toward propanol in hydroformylation of ethylene. |
