1-Methyl-2,3,4,5-tetranitropyrrole, a potential high energy density material, first reported in 1979 in only 0.28% overall yield, has been synthesized efficiently (in more than 5% overall yield) by following two alternate routes from 1-(triisopropylsilyl)pyrrole and 1-methylpyrrole. Detailed characterization shows that it is stable up to 196 °C and possesses a density of 1.93 g cm−3. The corresponding
1-甲基-2,3,4,5-四硝基吡咯是一种潜在的高能量密度材料,于1979年首次报道,其总收率仅为0.28%,它是通过以下两种替代方法有效合成的(总收率超过5%)由1-(三异丙基甲硅烷基)吡咯和1-甲基吡咯制得。详细的表征表明,它在高达196°C的温度下稳定,密度为1.93 g cm -3。相应的爆震速度和爆震压力分别为8950 ms -1和36.9 GPa。这些值比RDX略好一些,而其对冲击和摩擦的敏感度则比RDX低得多。此外,其熔点为100°C,进一步彰显了其在高能配方中作为可熔融浇铸材料的潜力。
