Abstract

New 7-amino-6-nitro-substituted [1,2,4]triazolo- and pyrazolo[1,5-a]pyrimidines were synthesized by an alternative strategy based on amino azoles and 2-nitro-3-(p-tolylamino)acrylonitrile. Unexpectedly, 3,5-dinitro-N-(p-tolyl)pyridine-2,6-diamine was formed when the starting 5-amino-1,2,4-triazoles contained NO₂ or CF₃ substituents.

7-氨基-6-硝基取代偶氮并[1,5-a]嘧啶的另一种合成方法

通过基于氨基唑和 2-硝基-3-(对甲苯氨基)丙烯腈的替代策略，合成了新的 7-氨基-6-硝基取代的 [1,2,4]唑并吡唑并[1,5-a]嘧啶。当起始的 5-氨基-1,2,4-三唑含有 NO2 或 CF3 取代基时，会意外地生成 3,5-二硝基-N-（对甲苯基）吡啶-2,6-二胺。

Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
