Rearrangement of 2,4-dinitro-, and 2, 4, 6-trinitrobenzylidenemalonates in reactions with primary, secondary and tertiary amines, both in the presence and in the absence of alcohols to give 2-amino-4-nitro-, and 2-amino-4,6-dinitrobenzoic acid derivatives is described. Depending on the reaction conditions, various rearrangement products, e.g. ester, ether, amide, are obtained selectively.
在有或无醇的存在下,二硝基和三硝基苯亚甲基丙二酸酯与一级、二级和三级胺反应,生成2-氨基-4-硝基和2-氨基-4,6-二硝基苯甲酸衍生物的重排反应。根据反应条件,可以选择性地得到各种重排产物,例如酯、醚、酰胺等。
