SYNTEZIS PERFLUOROPHENYLALKYL ETHERS BY THE CROSSED ANODIC CONDENSATION OF PERFLUOROCARBOXYLIC ACIDS WITH PERFLUOROPHENOLS

摘要

Perfluorophenols have an acidity comparable with pK_A of carboxylic acids and therefore the perfluorophenoxy anion can be adsorbed and oxidized at the high potentials on the surface of anode resulting in formation of perfluorophenoxy radicals.We suspected that these intermediates would be stable due to adsorbtion on the oxidized Pt-surface,and in the presence perfluorocarboxylic acids will be able to interact with carboxylate anion by charging the surface.
