New process direction was found in the reaction of polyfluoroarenethiols with fluorodichloromethane, chloroform, and bromoform in an alkaline medium consisting in the replacement of the thiol group by a hydrogen atom. This process competes with the formation of expected products, dihalomethyl polyfluoro-aryl sulfides and tris(arylsulfanyl)methanes. In reaction of 2,3,5,6-tetrafluorobenzenethiol with
在由氢原子取代硫醇基团的碱性介质中,聚氟亚芳基硫醇与氟代二氯甲烷,氯仿和溴仿的反应发现了新的工艺方向。该过程与预期产物,二卤代甲基多氟芳基硫化物和三(芳基硫烷基)甲烷的形成竞争。在2,3,5,6-四氟苯硫醇与二氯甲烷的反应中,获得了双(2,3,5,6-四氟苯基硫烷基)甲烷。多氟芳硫醇与五氟苄基氯的反应主要发生在氯原子的取代,五氟苯甲酰氯和五氟苯并三氯化物的对位上的氟原子的取代。
