摘要
对以2-甲基咪唑为反应底无制备1,1二氨基2,2二硝基乙烯(FOX7)的合成方法进行了改进,首次采用水或无机强酸实现中间体2(二硝基亚甲基)5,5二硝基4咪唑烷二酮的开环反应,稀硫酸为开环试剂时最优收率为196%;水开环法最优收率为358%,较氨水开环法有较大提高。经IR、MS、NMR和元素分析鉴定了产物结构。
A simple, convenient and efficient procedure for synthesis of 1,1 diamino 2,2 dinitroethylene(FOX 7) was described. Nitrations of 2 methylimidazole at ambient temperature affords 2 (dinitromethylene) 5,5 dinitro 4 imidazolidinone(compound 1), which reacts with water to give FOX 7. The key step was ring cleavage of compound 1 by addition of water to the reaction mixture or vice versa. By this means the synthetic pathway of 2 methylimidazole to FOX 7 could be achieved in a continuous process. The overall yield was 35 8%. The structure of FOX 7 was characterized by IR, MS, NMR and elemental analysis.
