A mixture of C6F5CHFCN and C6F5CF2CN is formed by the action of perchloryl fluoride on pentafluorophenylacetonirile in the presence of cesium fluoride.Hydrolysis of the second product gave the previously unknown heptafluorophenylacetic acid.This acid was also synthesized by the oxidation of perfluoroallylbenzene with potassium permanganate.The chloride, fluoride, amide, and methyl ester of heptafluorophenylacetic acid were obtained.
