Abstract
The synthesis of polychlorinated phenoxyphenols (PCPPs) by three methods is described: condensation of chlorinated guaiacols with chlorobenzene or chlorofluorobenzenes in the presence of base, followed by O-demethylation; reaction of chlorinated diphenyliodonium salts with chlorinated guaiacols, or of 4,4′-dimethoxydiphenyliodonium salts with chlorophenols, followed by O-demethylation; chlorination of lower-chlorinated phenoxyphenols.Keywords
