.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.
