• Aromatic nucleophilic substitution. Part 3. Preparation of novel 9-oxo-9H-thioxanthene- and 9-oxo-9H-xanthenedicarboximides and -dicarboxylates
  作者：Walter Fischer

  日期：1991.8.7

  By aromatic nucleophilic substitution followed by intramolecular acylation, 9-oxo-9H-thioxanthene- and 9-oxo-9H-xanthene-dicarboximides were prepared from nitro- or chlorophthalimides and the dianions of thiosalicylic and salicylic acids (Scheme). The 9-oxo-9H-thioxanthene-3,4-dicarboximides were converted to 9-oxo-9H-thioxanthene-3,4-dicarboxylic-acid derivatives such as anhydride, esters, and further

  通过芳香亲核取代，接着通过分子内酰化，9-氧代-9- ħ -thioxanthene-和9-氧代-9- ħ呫吨二甲酰亚胺从硝基或chlorophthalimides和硫代水杨酸和水杨酸的二价阴离子（其制备方案）。将9-氧代-9 H-硫代氧杂蒽-3,4-二甲酰亚胺转化为9-氧代-9 H-硫代氧杂蒽-3,4-二羧酸衍生物，例如酸酐，酯和其他酰亚胺。这些衍生物中的一些被证明是具有特殊性质的优异光敏剂，例如液体聚集形式，H 2 O溶解度，在亲脂性有机溶剂和聚合物中的溶解度或吸收波长的红移。

• Aromatic Nucleophilic Substitution. Part 1. Regiospecific Substitution of the Nitro Groups in 3,5-Dinitrophthalic-Acid Derivatives
  作者：Walter Fischer、Vratislav Kvita

  日期：1985.6.26

  The regioselectivity of nucleophilic substitution of the nitro groups in 3,5-dinitrophthalic anhydrides and 3,5-dinitrophthalimides (Scheme) with a variety of nucleophiles (Nu−) was studied. In all cases, the 3-nitro group was selectively substituted. With excess of the same nucleophilic reagent or with other nucleophiles, the 5-nitro group could subsequently be replaced.
