Alkylation of 3,5-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,4-triazole with haloalkanes afforded N-CH2R derivatives, and nitration furnished the corresponding bis-N-nitramine isolated as a trisodium salt. Treatment of the latter with CH3I resulted in denitration. Diazotization and oxidation of 3,5-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,4- triazole, its N-methyl and N-carboxy derivatives gave rise to the corresponding azido and nitro derivatives. Salts of 3,5-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,4-triazol-5-acetic acid with nitrogen-containing bases were synthesized. It was established that the character of reaction products of 3,5-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,4-triazole with formaldehyde depended on the acid-base properties of the medium.
将3,5-bis(4-氨基-1,2,5-恶嗪-3-基)-1,2,4-三唑与卤烷进行烷基化反应,得到N-CH2R衍生物,硝化反应则生成相应的双-N-硝亚胺,并以三钠盐的形式分离。对后者进行CH3I处理导致去硝化。3,5-bis(4-氨基-1,2,5-恶嗪-3-基)-1,2,4-三唑及其N-甲基和N-羧基衍生物的偶氮化和氧化反应产生了相应的叠氮和硝基衍生物。合成了3,5-bis(4-氨基-1,2,5-恶嗪-3-基)-1,2,4-三唑-5-乙酸与含氮碱基的盐。研究表明,3,5-bis(4-氨基-1,2,5-恶嗪-3-基)-1,2,4-三唑与甲醛反应生成物的性质取决于反应介质的酸碱性质。
