A convenient procedure for the synthesis of N-nitroaminofurazans by nitration of primary 3-amino-4-R-furazans (R = Me, NO2, phenyl-, methyl-NNO-azoxy-, tert-butyl-NNO-azoxy-, tert-butyldiazenyl-, etc.) with 66–77% aqueous nitric acid was developed. Depending on the concentration of HNO3, the reaction is carried out at a temperature from 18 to 55 °C, the yield of the products is 80–99%. 3-Nitramino-4-phenylfurazan with unsubstituted benzene ring was obtained by nitration of 3-amino-4-phenylfurazan.
研究人员开发了一种简便的程序,通过用 66-77% 的硝酸水溶液硝化伯胺基 3-氨基-4-R-呋喃(R = Me、NO2、苯基、甲基-NNO-氮氧基、叔丁基-NNO-氮氧基、叔丁基二氮基等)来合成 N-硝基氨基呋喃。根据 HNO3 的浓度,反应在 18 至 55 ℃ 的温度下进行,产物的收率为 80-99%。通过对 3-氨基-4-苯基呋咱进行硝化,得到了具有未取代苯环的 3-硝氨基-4-苯基呋咱。
