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.
描述了通过三种方法合成多氯化酚氧基酚(PCPPs):在碱存在下,将氯化香豆素与氯苯或氯氟苯缩合,随后进行O-去甲基化;氯化的二苯基碘盐与氯化香豆素反应,或4,4'-二甲氧基二苯基碘盐与氯酚反应,随后进行O-去甲基化;氯化低氯化酚氧基酚。
