The hydrolysis of the acid fluorides of 2-fluorocarbonyl(methoxycarbonyl)-2-trifluoromethyl-4-pentenoic acids (I) and (II), and of 2-fluorocarbonyl-(methoxycarbonyl)-2-trifluoromethyl-3,4-pentadienoic acids (III) and (IV) gave, under mild conditions, 2-trifluoromethyl-4-pentenoic acid (V) and 2-trifluoromethyl-3,4-pentadienoic acid (VII) or their methyl esters (VI) and (VIII). The reactivity of these compounds was studied.
