实验步骤: A 500 ml flask was flushed with nitrogen to displace the air with nitrogen, and was charged with 43.0 g (0.50 mol) of methacrylic acid, 0.95 g (5 mmol) of p-toluenesulfonic acid monohydrate (supplied by Wako Pure Chem. Ind. Ltd.) and 100 g of toluene. Separately 74.0 g (0.50 mol) of 2-methyleneadamantane, prepared by the same procedures as described in Reference Example 1, was dissolved in 100 g of toluene. The obtained solution of 2-methyleneadamantane in toluene was dropwise added to the content in the flask over a period of about 3 hours, while the content was maintained at a reaction temperature of about 5° C. Then the content was stirred for 5 hours at the same temperature. After completion of the reaction, the residual catalyst was neutralized by adding 40.0 g (50 mmol) of a 5% aqueous sodium hydroxide solution, and the neutralized liquid was washed with an aqueous saturated sodium chloride solution. The thus-obtained organic phase was subjected to column chromatography, and further, analyzed by NMR and mass spectrometry. Thus, 106.2 g (yield: 90.8%) of the object 2-methyl-2-adamantyl methacrylate was obtained. A 500 ml flask was flushed with nitrogen After completion of the reaction the neutralized liquid was washed with an aqueous saturated sodium chloride solution

实验步骤: A 500 ml flask was flushed with nitrogen to displace the air with nitrogen, and was charged with 36.0 g (0.50 mol) of acrylic acid, 0.5g (5mmol) of sulfuric acid and 100 g of toluene. Separately 88.8 g (0.60 mol) of 2-methyleneadamantane, prepared by the same procedures as described in Reference Example 1, was dissolved in 100 g of toluene. The obtained solution of 2-methyleneadamantane in toluene was dropwise added to the content in the flask over a period of about 3 hours, while the content was maintained at a reaction temperature of about 20° C. Then the content was stirred for 5 hours at the same temperature. After completion of the reaction, the residual catalyst was neutralized by adding 40.0 g (50 mmol) of a 5% aqueous sodium hydroxide solution, and the neutralized liquid was washed with an aqueous saturated sodium chloride solution. The thus-obtained organic phase was subjected to column chromatography, and further, analyzed by NMR and mass spectrometry. Thus, 100.7 g (yield: 91.5%) of the object 2-methyl-2-adamantyl acrylate was obtained. A 500 ml flask was flushed with nitrogen After completion of the reaction the neutralized liquid was washed with an aqueous saturated sodium chloride solution

实验步骤: A 500 ml flask was flushed with nitrogen to displace the air with nitrogen, and was charged with 70.0 g (0.50 mol) of α-trifluoromethylacrylic acid (supplied from Tosoh F-tech Inc.), 1.0 g (10 mmol) of sulfuric acid and 100 g of toluene. Separately 88.8 g (0.60 mol) of 2-methyleneadamantane, prepared by the same procedures as described in Reference Example 1, was dissolved in 100 g of toluene. The obtained solution of 2-methyleneadamantane in toluene was dropwise added to the content in the flask over a period of about 3 hours, while the content was maintained at a reaction temperature of about 5° C. Then the content was stirred for 15 hours at the same temperature. After completion of the reaction, the residual catalyst was neutralized by adding 40.0 g (50 mmol) of a 5% aqueous sodium hydroxide solution, and the neutralized liquid was washed with an aqueous saturated sodium chloride solution. The thus-obtained organic phase was subjected to column chromatography, and further, analyzed by NMR and mass spectrometry. Thus, 133.9 g (yield: 93.0%) of the object 2-methyl-2-adamantyl α-trifluoromethylacrylate was obtained.

实验步骤: One liter flask equipped with a Dean-Stark condenser was charged-with 166.3 g (1.0 mol) of 2-methyl-2-adamantanol (supplied by Sigma-Aldrich Co.), 2.0 g (20 mmol) of sulfuric acid and 500 g of toluene. The content was heated to the solvent reflux temperature. While toluene and water produced through the reaction were collected as an azeotrope by the Dean-Stark condenser, the reaction mixture was refluxed for 2 hours. After completion of the reaction, the catalyst was removed by washing the reaction mixture with water and the obtained organic phase was concentrated to dryness to give 152.5 g of white solid 2-methyleneadamantane (purity: 99.0%, yield: 98.0%).
