Heptafluoroisobutenyl methyl ether having the following formula: ##STR1## is oxidized with ozone to produce perfluoro(2-methyl-1,2-epoxy-propyl) methyl ether. The resulting intermediate compound is allowed to react with an aromatic compound ArH to produce .alpha.,.alpha.-bis(trifluoromethyl)arylacetic acid methyl ester having the following formula: ##STR2## By hydrolysis, decarboxylation and further hydrolysis of the ester compound, .alpha.,.alpha.-bis(trifluoromethyl)arylacetic acid for use as raw materials for medicines, agricultural chemicals, liquid crystals, etc. or reagents for determining an optical purity can be obtained.
具有以下化学式的七氟异丁烯基甲醚:##STR1## 被臭氧氧化,产生全氟(2-甲基-1,2-环氧-丙基)甲醚。然后,中间产物与芳香族化合物ArH反应,产生具有以下化学式的α,α-双(三氟甲基)芳基乙酸甲酯:##STR2## 经过酯水解、脱羧和进一步的水解,可以得到α,α-双(三氟甲基)芳基乙酸,用作药品、农药、液晶等原材料,或用作测定光学纯度的试剂。
