Electrochemical Synthesis of Polyphenylenes in Room-Temperature Ionic Liquid Butylpyridinium Chloride-AlCl3

Electrochemical oxidation of benzene in room-temperature ionic liquids N-butylpyridinium chloride-AlCl3 under controlling the potential on platinum and glassy carbon composite electrodes is studied. Linear polymers with degree of polymerization of 8-120 are obtained. It is shown that the degree of polymerization increases with increasing the anode potential.
