IR spectroscopic study on surface-mediated reductive carbonylation of hydrated SiO2-supported Ru(NO3)(3)
The surface-mediated reductive carbonylation of hydrated SiO2-supported Ru(NO3)(3) has been studied by IR spectroscopy. At 25 degreesC, hydrated Ru(NO3)(3)/SiO2 reacts with CO to give a mixture of Ru(CO)(2)(OSi)(2) and Ru(CO)(3)(OSi)(2). At 100 degreesC, hydrated Ru(NO3)3/SiO2 is converted to a mixture of Ru(CO)(2)(OSi)(2) and Ru(CO)(3)(OSi)(2) under 100 Torr of CO, and a mixture of Ru-3(CO)(12) and Ru(CO)(3)(OSi)(2) under 700 Torr of CO.
