Nucleophilic substitution of 2,3,5,6-tetrachloronitrobenzene with secondary amines such as morpholine, piperidine, pyrrolidine, diethylamine, and ethylmethylamine, and primary amines such as aniline, benzylamine, butylamine, isobutylamine, s-butylamine, and t-butylamine, under high pressure of 0.6 GPa at 50 °C for 1—40 h in tetrahydrofuran gave nitro group substitution products together with ortho-mono-
2,3,5,6-四氯硝基苯与吗啉、哌啶、吡咯烷、二乙胺和乙基甲胺等仲胺和苯胺、苄胺、丁胺、异丁胺、仲丁胺和叔丁胺等伯胺的亲核取代,在 0.6 GPa 的高压下,在四氢呋喃中 1-40 小时,得到硝基取代产物以及邻-单-、间-单-、邻-邻-和邻-间-二氯取代产物。这些产物的比例取决于胺的体积和数量以及反应条件。硝基取代和氯取代的选择性主要取决于胺的体积。
