The hydrogenolysis of glycols to hydrocarbons is a reaction of potential value for the production of chemicals and fuels from biomass-derived polyols. We find that [Cp*Ru(CO)2]2 (Cp* = 1,2,3,4,5-pentamethylcyclopentadienyl) catalyzes the hydrogenolysis of glycols to alkanes and of epoxides to alkanes/alkenes by molecular hydrogen at 170–200 °C and 4–27 atm; the product yields range from moderate to excellent. Moreover, we also established a novel process that produces alkanes with a lower number of carbons from glycols: e.g., toluene from 1-phenyl-1,2-ethanediol.
