to give 3,4,5,6-tetrachloro-o-phenylenediamine (II; R = Cl) in good yield. The corresponding diamines (II; R = Me or F) were obtained similarly from 4,5,7-trichloro-6-methyl(or fluoro)benzotriazole. Alternative syntheses of the tetrachloro- and methyltrichloro-phenylenediamines are described. Benzimidazoles, quinoxalines, and other heterocyclesderived from the diamines, especially from tetrachloro-o-phenylenediamine
用锌和盐酸将4,5,6,7-四氯苯并三唑及其1-羟基衍生物还原,得到高收率的3,4,5,6-四氯-邻苯二胺(II; R = Cl)。类似地从4,5,7-三氯-6-甲基(或氟)苯并三唑获得相应的二胺(II; R = Me或F)。描述了四氯和甲基三氯-苯二胺的替代合成。据报道,苯并咪唑,喹喔啉和其他衍生自二胺,尤其是衍生自四氯-邻苯二胺的杂环。
