6-trinitrostyrene derived from 2,4,6-trinitrotoluene adds nucleophiles (thiophenol, aniline, and aliphatic amines) at the vinyl fragment to form the corresponding β-X-ethyl-2,4,6- trinitrobenzenes (X = PhS, PhNH, or R2N). In the reactions with primary aromatic amines, the initially formed adducts undergo intramolecular replacement of the nitro group followed by aromatization of the indolines that formed
发现衍生自 2,4,6-三硝基甲苯的 2,4,6-三硝基苯乙烯在乙烯基片段处添加亲核试剂(苯硫酚、苯胺和脂肪胺)以形成相应的 β-X-乙基-2,4 的条件, 6- 三硝基苯(X = PhS、PhNH 或 R2N)。在与伯芳香胺的反应中,最初形成的加合物经历硝基的分子内置换,然后形成的二氢吲哚芳构化为相应的 N-取代的 4,6-二硝基吲哚。
