Multi-substituted partially fluorinated aromatic compounds, such as naphthalene derivatives could be readily prepared by the reaction of 1,4-dilithio-1,3-dienes with hexafluorobenzene via double nucleophilic substitution. When these dilithium reagents were treated with hexachlorobenzene, chloropentafluorobenzene or bromopentafluorobenzene, chlorine–lithium or bromine–lithium exchange reactions, instead
多取代的部分氟化的芳族化合物,如萘衍生物,可以通过双亲核取代反应使1,4-二硫代-1,3-二烯与六氟苯反应而制得。当用六氯苯,氯五氟苯或溴五氟苯处理这些二锂试剂时,发生了氯-锂或溴-锂交换反应,而不是亲核取代。
