Abstract
Methanol, together with methane, is formed for the first time by homog eneous hydrogenation of CO2 using a catalytic system consisting of Ru- 3(CO)(12) and alkaline iodides in N-methylpyrrolidone (NMP) solution a t 240 degrees C. The time course of the reaction indicates the success ive formation of CO, methanol, and then methane. The FT-IR analysis of the resulting reaction solutions reveals the formation of several spe cies of ruthenium carbonyl anion and their mutual interchanges during the reaction. A mechanism for the overall reaction is proposed, based on these results.
