Abstract
The Rh–ReOx/SiO2 (Re/Rh = 0.5) exhibited high activity in the hydrogenolysis of ethers with an OH group. The Csingle bondO bond neighboring single bondCH2OH group was selectively dissociated: The hydrogenolysis of tetrahydro-5-methyl-2-furfuryl alcohol and 2-isopropoxyethannol gave 1,5-hexanediol and ethanol + isopropanol, respectively. This tendency suggests the regioselective Csingle bondO dissociation mechanism via anion intermediate formed by the attack of hydride and the subsequent protonation of the anion.
