of group-VIII metal catalysts has been examined in the hydrogenation of nonconjugated enones at ambient temperature under an atmospheric pressure of hydrogen. A cobalt catalyst gave high yields of unsaturated alcohols from trialkylated olefinic ketones. Osmium showed the highest selectivity among platinum metal catalysts for the reduction of the carbonyl bond in the hydrogenation of trialkylated olefinic

The products of novel reductive cyclization, 1-adamantanol and 1-methyl-2-oxa-adamantane, were obtained in the hydrogenation of 7-methylenebicyclo[3.3.1]nonan-3-one over group VIII metal black catalysts in ethanol or cyclohexane. 1-Adamantanol was produced over Pd, Rh, Co and Ni catalysts, and 1-methyl-2-oxa-adamantane only over Co catalyst in cyclohexane.
7-亚甲基双环[3.3.1]壬烷-3-酮在乙醇或环己烷中加氢得到新型还原环化产物1-金刚烷醇和1-甲基-2-氧杂-金刚烷. 1-金刚烷醇是在 Pd、Rh、Co 和 Ni 催化剂上生产的,而 1-甲基-2-氧杂-金刚烷仅在环己烷中的 Co 催化剂上生产。
