The catalytic hydrogenation of 2–hydroxycyclohexanone has been investigated on ruthenium, nickel, rhodium, platinum and palladium. The reaction was completed usually within several hours under an atmospheric pressure of hydrogen at room temperature. It was found that ruthenium and nickel catalysts produce more cis–cyclohexane–1, 2–diol than trans‐diol; while platinum and palladium catalysts give rise to more trans–diol than cis– form. Two adsorbed models, weak and strong, for the substrate were presented to account for the observed hydrogenation selectivity.
