.alpha.-(trifluoromethyl)arylacetic acid for use as raw materials for medicines, agricultural chemicals, liquid crystals etc. or reagents for determining an optical purity is readily obtained through very simple reaction steps, i.e. by reacting a perfluoro(2-methyl-1,2-epoxypropyl)ether compound obtainable by ozone, oxidation of a heptafluoroisobutenyl ether compound with an aromatic compound ArH to afford an .alpha.,.alpha.-bis(trifluoromethyl)arylacetic acid ester, followed by decarboxylation and hydrolysis of the resulting ester compound.
.alpha.-(三氟甲基)芳基乙酸可用作药品、农药、液晶等原材料,或作为测定光学纯度的试剂。通过非常简单的反应步骤即可轻松获得,即通过将可由臭氧和七氟异丁烯醚化合物氧化得到的全氟(2-甲基-1,2-环氧丙基)醚化合物与芳香族化合物ArH反应,得到.alpha.,.alpha.-双(三氟甲基)芳基乙酸酯,随后脱羧和水解所得到的酯化合物。
