実験手順: To a mixture of di-μ-chlorobis(1,5-cyclooctadiene)diiridium(I) [Ir(cod)Cl]2 (6.7 mg, 0.01 mmol) and sodium carbonate (64 mg, 0.6 mmol) in toluene (1.0 ml), 1,3,5-adamantanetriol (1 mmol) and vinyl acetate (9 mmol) were added, followed by stirring at 100° C. in an atmosphere of argon gas for 5 hours. The reaction mixture was analyzed by gas chromatography to find that 1,3,5-tris(vinyloxy)adamantane, 3,5-bis(vinyloxy)-1-adamantanol, and 5-vinyloxy-1,3-adamantanediol were produced in yields of 52%, 18%, and 8%, respectively, with a conversion from 1,3,5-adamantanetriol of 97%. were added

実験手順: 92.12 g (0.5 mol) of 1,3,5-adamantanetriol are suspended in 153.14 g (1.5 mol) of acetic anhydride. Subsequently, 10 drops of concentrated sulfuric acid are added and the mixture is stirred on a rotary evaporator (without vacuum) until a homogeneous solution has formed. Subsequently, the mixture is heated to 100° C. under reflux for 2 h. After cooling, the reaction mixture is added to 300 ml of ice-water and extracted with dichloromethane. The combined organic phases are deacidified with sodium carbonate solution and washed with water. The mixture is dried over magnesium sulfate and filtered, and the solvent is removed under reduced pressure. 150.50 g (0.48 mol; 97.0%) of a colorless oil are obtained. has formed under reflux for 2 h After cooling extracted with dichloromethane washed with water The mixture is dried over magnesium sulfate filtered the solvent is removed under reduced pressure 150.50 g (0.48 mol; 97.0%) of a colorless oil are obtained

実験手順: A mixture of 1.68 grams (10 millimoles) of 1,3-adamantanediol, 0.13 gram (0.8 millimole) of N-hydroxyphthalimide, 0.015 gram (0.06 millimole) of Co(AA)2 and 25 milliliters of acetic acid was stirred under an oxygen atmosphere at a temperature of 95° C. for 6 hours. Thus, 1,3-adamantanediol was transformed, with a transformation rate of 99%, into 1,3,5-adamantanetriol (selectivity for 1,3-adamantanediol 37%, yield 37%) and 1,3,5,7-adamantanetetraol (selectivity for 1,3-adamantanediol 62%, yield 62%). The selectivity for the alcohols was 99%.
