Abstract

The syntheses of 46 methoxy-polychlorobiphenyls (MeO CBs), containing 3 to 7 chlorine atoms, are described. The MeO CBs were synthesized via the Cadogan diaryl coupling reaction of the appropriate polychloroaniline and polychloroanisole, or via the Ullmann coupling of a polychloroiodobenzene and 4-iodoanisole with subsequent chlorination of the isolated 4-MeO CB product. The synthesized MeO CBs were characterized by electron ...
