〈研究論文〉Grignard 反応によるレジスト材料の開発 〈Original Papers〉Development of resist material by Grignard reaction 野村, 正人 ノムラ, マサト 村井, 義洋 ムライ, ヨシヒロ Adamantyl resist Grignard reagent 2-Methyl-2-adamantanol [Abstract]For adamantyl resist, Ether was used as the solvent in the conventional synthetic method. Ether is an excellent solvent for organic synthesis reactions, as it is reaction-inactive and has the property of dissolving many organic compounds at the same time, and because it has a low boiling point (34.5℃), it can be easily removed from the extract and recovered by distillation. Is. However, the industrial use of Ether is extremely volatile and flammable, which is extremely dangerous. In this study, we decided to synthesize adamantane resist using THF as a solvent and Grignard reagent as a reactant. The purpose was to synthesize adamantanol, which is an alcoholic substance required as a precursor of this. Here, the THF used in this experiment is a 5-membered ring Ether, which is widely used as a solvent for the reaction, but is generally used for a reduction reaction with LiAlH4, a Grignard reagent, and a reaction using an organic Li reagent. Grignard reagents act as nucleophiles for carbonyl compounds. The R group of the Grignard reagent attacks the carbonyl carbon to form a new carbon-carbon bond. The product is an alkoxide, which is hydrolyzed to an alcohol. Using this solvent, 2-Methyl-2-adamantanol required as a precursor was synthesized by 2-Adamantanone and Grgnard reagents Methyl magunesium Chloride and Methyl magunesium bromide. application/pdf 近畿大学工学部 2021-02-20 jpn departmental bulletin paper NA https://kindai.repo.nii.ac.jp/records/21384 2434592X 近畿大学工学部研究報告 Research reports of the Faculty of Engineering, Kindai University 54 23 27 https://kindai.repo.nii.ac.jp/record/21384/files/AN00063799-20210220-0023.pdf application/pdf 1.1 MB 2021-03-05
