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.
在硝基基团的亲核取代的3,5- dinitrophthalic酸酐和3,5- dinitrophthalimides(区域选择性方案)与各种亲核试剂的(女- )进行了研究。在所有情况下,3-硝基均被选择性取代。在过量的相同亲核试剂或其他亲核试剂的情况下,随后可以取代5-硝基。
